Introduction

In this module, you complete a supervised practical project that combines forge preparation, safe material handling, controlled heating, hand forging, quality checking and reflection. The recommended learning product is a simple forged hook or comparable small decorative component in identified low-carbon steel. Your instructor selects the exact stock size, project drawing, forge type, fuel, tooling and level of learner participation to suit local equipment, risk assessment and your demonstrated competence.

The professional aim is not merely to make a finished object. You are expected to show that you can plan the sequence, recognise hazards, select suitable tools and material, communicate around hot work, control the workpiece through repeated heats, measure progress, minimise waste and explain what you would improve next time.

The current Skills England Blacksmith occupational standard ST0378 version 1.1 describes the role as designing, shaping and joining metal components by hot forging and other metalworking processes for small-batch, bespoke and heritage work. Its knowledge and skills include health and safety, materials, tools, quality, safe fuel handling, lighting and operating a forge, identifying hazards, hot forging, maintaining equipment and evaluating work. The standard is Level 3 and is approved for delivery in England. The current version shown by Skills England was updated on 10 December 2025.

Learning Outcomes

By the end of this module, you should be able to explain the relationship between fuel, air, heat, material condition and workability; identify forgeable stock from reliable information rather than guesswork; prepare a supervised forging task using a drawing or sample; select and check tongs, hammer, anvil and measuring tools; describe and apply risk controls using the hierarchy of control; complete a simple hot-forging sequence under supervision; recognise common process faults before they become safety or quality failures; compare the finished work with agreed criteria; record resource use and waste; and reflect on decisions using evidence from the job.

Official UK Source Check and Scope

The following sources were checked for this course on 1 September 2026. They are included so that an instructor or expert reviewer can verify the current position.

Area	Official source and current point	Application in this module
Risk assessment	HSE: Managing risks and risk assessment at work states that employers must identify hazards, evaluate risk and eliminate or control risk under the Management of Health and Safety at Work Regulations 1999.	A practical project begins with the local risk assessment and agreed controls, not with lighting the forge.
Work equipment	HSE: PUWER overview requires work equipment to be suitable, maintained, inspected where necessary and used by people who have received adequate information, instruction and training.	Forges, blowers, power hammers, grinders and other work equipment are used only when the learner is authorised and trained for that task.
Fire and flammable substances	HSE: DSEAR requires employers to assess and control safety risks from dangerous substances, including flammable gases such as LPG.	Gas-forge fuels, fuel storage, ignition sources and emergency arrangements are controlled by the employer and site procedure.
Hazardous substances and fume	HSE: COSHH and HSE: COSHH risk assessment require harmful dust, fume, vapour and gas exposures to be identified and controlled.	Unknown, painted, plated, galvanised or contaminated stock is not heated unless it has been specifically assessed and controlled.
Ventilation and extraction	HSE: Ventilation in the workplace requires adequate fresh air in enclosed workplaces; HSE: Local exhaust ventilation covers extraction of harmful airborne contaminants.	Smoke or fume escaping into the breathing zone is a stop-and-report condition. General ventilation is not a substitute for task-specific extraction where it is required.
Noise	HSE: employers' responsibilities for noise gives lower and upper daily or weekly exposure action values of 80 dB(A) and 85 dB(A), with an exposure limit value of 87 dB(A) after hearing protection is taken into account.	Hammering and forging can create harmful impact noise. Control noise at source and by work organisation before relying on hearing protection.
Heat stress	HSE: heat stress identifies workload, radiant heat, humidity, clothing and individual factors as relevant to heat-stress risk.	Provide cool drinking water, suitable breaks and workload controls; report symptoms such as dizziness, nausea, confusion or excessive fatigue immediately.
Manual handling	HSE: Manual handling at work requires hazardous manual handling to be avoided where reasonably practicable, assessed where it cannot be avoided, and reduced so far as reasonably practicable.	Use stock racks, trolleys, hoists or team handling where the local assessment requires them; do not treat lifting technique as the only control.
PPE	HSE: PPE at work from 6 April 2022 states that engineering controls and safe systems should be considered before PPE and that suitable PPE must be provided, maintained and supported by information, instruction and training when required.	Wear only the PPE specified for the task and workplace. PPE is the final layer, not a substitute for a safe forge, ventilation or good work organisation.
PPE product standards	GOV.UK: Designated standards for PPE was updated on 8 August 2026. BSI lists BS EN ISO 16321-1:2022+A1:2025 as current for occupational eye and face protection and BS EN 407:2020 for protective gloves against thermal risks.	Standards help competent people specify suitable products; they do not tell a learner which PPE to choose without a task-specific risk assessment.
Vocational pathway	Skills England: Blacksmith ST0378 v1.1 is an England apprenticeship occupational standard at Level 3, with a typical duration of 48 months.	The course vocabulary and performance expectations are aligned to this England occupational context, but completing this aiMOOC does not award the apprenticeship.

Core Concepts

The Forge System: Fuel, Air, Heat and Workpiece

A traditional forge is a controlled heating system. In a solid-fuel forge, the smith manages a hearth or firepot containing coal or coke, air entering through a tuyere, and the position of the workpiece within the active fire. A blower or bellows supplies air. Too little effective air can leave the fire sluggish; excessive blast or poor fire management can waste fuel, increase oxidation and contribute to overheating. The goal is not the largest possible fire but a stable, suitable hot zone for the stock and operation.

A gas forge uses a different control system: fuel gas, air mixing, burners, refractory lining and a hot chamber. Because LPG or other fuel gas is a dangerous substance, gas-forge operation must follow the employer's DSEAR assessment, manufacturer instructions and site procedures. Learners must never improvise burner settings, leak tests, ignition or shut-down procedures.

Forgeable Materials and Material Identity

Forgeable means that a material can be plastically deformed by forging within a suitable processing range without unacceptable cracking, burning or loss of required properties. For vocational work, material identity matters as much as heat.

Low-carbon or mild steel is widely used for introductory and general artistic blacksmithing because it normally has a forgiving hot-working range and good formability. Medium-carbon and high-carbon steels need more careful heat control and may require specific heat-treatment knowledge. Alloy steels can have narrower processing windows or special requirements. Wrought iron, where genuinely identified, behaves differently from modern mild steel because of its slag-fibre structure. Stainless steels and non-ferrous alloys require material-specific procedures and are outside this introductory project unless the training provider has a separate approved method.

Do not identify steel only by appearance, sparks or where scrap came from. Use supplier markings, stock records, certificates, drawings or other approved traceability. If the material is unknown, coated, plated, painted, contaminated or possibly galvanised, quarantine it and ask a competent person before any heating. HSE notes that hot work on galvanised material can be associated with metal fume fever, and heating old leaded paint can release hazardous lead fume.

The visible colour of hot steel is a useful workshop cue, but it is not a calibrated thermometer. Ambient lighting, surface scale, alloy composition and the observer affect what you see. Follow the material specification, approved process and instructor's judgement rather than memorising one colour as a universal forging temperature.

Heat, Workability and Metal Flow

When steel is heated into its suitable forging range, less force is needed to change its shape. The smith uses compressive blows and support from the anvil or tooling to direct metal flow. Basic hand-forging actions include drawing out, upsetting, bending, punching, fullering and swaging. In this project, the emphasis is on drawing a taper, controlling section and bending to a drawing or sample.

Working too cold increases effort and can produce poor transitions or cracks in unsuitable materials. Working too hot can cause excessive scale, decarburisation and, in severe cases, burning. A good workflow alternates controlled heating, forging, measuring and reheating instead of trying to complete the shape in one heat.

Observation resource: “Lesson #1 – Drawing out”, linked by the Northwest Ohio Blacksmiths association as a beginner resource. Compare the demonstrated metal flow with your instructor's method and your local project criteria.

Scale, Clinker and Other Process Residues

Scale is iron oxide that forms on the hot steel surface. Some scale is expected in open-forge work, but heavy scale can indicate excessive heating time, oxidising conditions or inefficient workflow. Brush or clear scale only with the approved tool and direction so that hot particles do not endanger others.

Clinker is fused mineral residue that can accumulate in a coal fire. Clinker can disturb airflow and the shape of the fire. Its removal is a supervised fire-management task because both the tool and clinker may be extremely hot. Place removed clinker only in the designated fire-resistant container.

Other waste can include cut-offs, grinding dust, spent abrasives, contaminated water, refractory debris and used consumables. Keep waste streams separated according to the workshop's environmental and hazardous-waste procedures.

Materials for the Supervised Project

The default material is identified low-carbon steel supplied through the training provider. The instructor sets the section and starting length from the drawing, allowances and learner level. You may also use approved chalk or soapstone for cold marking, a metal rule, square and callipers for inspection, and the workshop's approved finishing consumables.

Do not bring unknown scrap into the forge. Reused steel can be environmentally sensible only when its grade, coatings, previous contamination and suitability are known well enough for the process risk assessment and quality requirement.

Risk Controls for Forge Work

A competent workshop controls risk using the hierarchy of control: eliminate hazards where possible, substitute safer materials or methods where appropriate, use engineering controls, organise safe systems of work, and use PPE as the final layer. This is particularly important in a forge because heat, fire, moving tools, fume and impact noise are present at the same time.

Hazard	Example	Preferred controls before or with PPE
Fire or explosion	LPG leak, fuel stored badly, ignition of combustibles	DSEAR assessment, suitable forge installation, controlled fuel storage, clear hot-work area, emergency arrangements, trained and authorised operators
Combustion products and fume	Coal smoke, carbon monoxide, heated coatings or contamination	Identified clean stock, suitable source control or extraction, adequate fresh air, maintained LEV where required, stop work if fume control is ineffective
Burns and radiant heat	Hot stock, hot tongs, clinker, forge opening	Defined hot zone, correct work holding, safe resting places, barriers or spacing, workload and break planning, task-specific protective clothing and PPE
Flying scale and fragments	Hammering oxidised steel or chipped tooling	Dressed tools, controlled striking area, screens where appropriate, eye and face protection selected from the risk assessment
Noise	Repetitive hand hammering, power hammer impact	Quieter methods or tooling where practicable, equipment maintenance, separation and exposure-time control, hearing protection where required
Manual handling	Long bar stock, heavy anvil tooling, awkward workpiece	Avoid unnecessary moves, use racks and handling aids, shorten carrying distances, team handling where assessed, task planning
Work equipment failure	Loose hammer head, damaged cable, unguarded blower	Pre-use checks, maintenance, inspection, isolation and reporting, PUWER-compliant training and authorisation
Slips, trips and struck-by risk	Stock on the floor, trailing leads, crowded anvil zone	Clear gangways, designated stock positions, cable management, one-person striking zone unless a planned team-forging method is being used
Hot metal mistaken for cold	A darkened workpiece left on a bench	Treat recently heated metal as hot, use the designated hot-metal area and local warning system, communicate clearly
Heat stress	Sustained forging near radiant heat	Suitable ventilation, breaks, drinking water, workload control, monitoring and prompt reporting of symptoms

Stop-Work Triggers

Stop the task, make the work area safe within your training and report to the instructor or supervisor if stock identity is uncertain; a coating or contamination is discovered; tongs do not grip securely; a hammer head or handle is defective; extraction or ventilation appears ineffective; smoke or fume enters the breathing zone; a gas smell, suspected leak or abnormal flame is noticed; a guard or control is damaged; a person enters the striking or hot-metal zone unexpectedly; you become dizzy, confused, nauseous, excessively fatigued or unwell; a fire, burn, equipment fault or near miss occurs; or the process moves outside the agreed method.

PPE: Selection, Not Guesswork

Typical forge PPE may include occupational eye protection, hearing protection where required, safety footwear, task-specific workwear and other protective equipment selected from the local risk assessment. Depending on the task, thermal hand protection may be specified, but gloves are not automatically suitable for every forge or machine task. A glove can reduce one risk while creating another, such as poorer grip or entanglement near rotating machinery. Follow the employer's instruction for each operation.

BSI's current occupational eye and face protection standard BS EN ISO 16321-1:2022+A1:2025 covers hazards including impact, hot solids, molten metal, heat and flame. BS EN 407:2020 covers protective gloves and hand-protection equipment against thermal risks. These standards describe product performance; they do not replace competent PPE selection or user training.

Practical Project

Project Brief: Supervised Forged Hook or Comparable Small Component

Produce one small forged component from identified low-carbon steel to an instructor-issued drawing, sample or template. The object should require at least one controlled taper or drawn section and one bend or curve. The work must be completed using the workshop's approved forge and hand tools, with the instructor deciding which forge-management actions you may perform.

Required evidence is a planning note, material identification record, completed risk-control check, at least one in-process measurement, the finished component, a quality inspection, a short resource-use note and a structured reflection. Photographs may be used where the workplace permits them.

Step-by-Step Demonstration

This sequence is written for a competent instructor demonstration followed by supervised learner practice. It deliberately does not provide a standalone ignition recipe. The local method statement, forge manufacturer instructions and trainer directions control all operational details.

Read the job information. Confirm the drawing or sample, target features, allowed tolerances, finish expectation and stopping point for the exercise.
Confirm the material. Read the stock label or record, check the section and starting allowance, and reject or quarantine unidentified or coated material.
Review the risk controls. Confirm the authorised forge type, extraction or ventilation, hot-metal area, fire arrangements, noise controls, emergency route, drinking water and required PPE.
Inspect hand tools and work holding. Choose tongs that grip the stock securely, inspect the hammer and confirm that the anvil and any tooling are stable.
Prepare the workspace. Remove trip hazards, position measuring tools where they will remain cool, keep combustibles out of the hot-work zone and make sure other people understand the striking area.
Observe or assist with forge establishment only as authorised. The instructor lights and stabilises the forge or supervises the authorised learner procedure. Do not improvise fuel, burner or airflow settings.
Heat the workpiece under supervision. Position the identified stock as directed and monitor the material condition. Keep attention on both the fire and the people around the work area.
Transfer with control. Grip the stock securely with suitable tongs, communicate “hot metal” according to local practice and move directly to the anvil without crossing another person's working zone.
Forge the first feature. Use controlled blows to begin the taper or drawn section, rotate the stock as needed for even section and stop before the material becomes unsuitable to continue forging.
Reheat instead of forcing the work. Return the workpiece to the forge when instructed rather than compensating for lost workability with harder blows.
Measure between heats. Check length, section, straightness or the project-specific dimension while the work is in a safe measuring condition and adjust the next forging step from evidence.
Form the bend or curve. Use the approved anvil feature, jig or bending tool, keeping your hands and body clear of pinch, strike and rebound zones.
Correct only while there is safe process margin. If alignment, profile or dimensions drift, discuss the correction with the instructor. Do not keep reheating a damaged or suspect workpiece simply to save it.
Finish the hot work safely. Place the workpiece in the designated hot-metal location and cool it only by the specified method. Do not quench automatically; cooling method can affect material condition and create steam or splash hazards.
Inspect quality when safe to handle. Compare the work with the drawing, sample or template; check dimensions, symmetry or alignment, surface condition and evidence of cracks, folds or burning.
Close the job. Follow the supervised forge shut-down or fire-safe procedure, return tools, segregate scrap and waste, record any defect or near miss and complete the reflection while decisions are fresh.

The diagram shows a repeating craft cycle rather than a one-way recipe. Good smithing depends on feedback: each heat gives information about material movement, tool choice, fire condition and the next decision.

Common Errors and Recovery

Common error	Likely consequence	Professional response
Heating unknown or coated stock	Uncontrolled fume exposure, unsuitable material response	Stop, quarantine, identify and reassess before any hot work
Trying to make the largest possible fire	Fuel waste, excessive scale, poor control	Re-establish only the fire size needed for the stock and operation under the approved method
Excessive blast or leaving stock unattended	Oxidation, overheating or burning	Reduce exposure time and correct fire management under instructor direction
Continuing to hammer when the workpiece has lost useful forging heat	More effort, poor finish, greater risk of cracking in some steels	Reheat at the correct time instead of striking harder
Loose or poorly matched tongs	Workpiece rotation or drop	Stop and change or adjust work holding before continuing
Heavy blows before alignment is established	Dents, fish-mouthing, twist or loss of section control	Use controlled initial blows and check geometry early
Measuring only at the end	Dimension drift and unnecessary rework	Measure at planned checkpoints between heats
Putting dark hot metal on a normal bench	Serious contact-burn risk to another person	Use the designated hot-metal area and local warning system
Automatic quenching	Unwanted hardness, distortion, steam or splash hazard	Cool only by the method specified for the material and task
Treating PPE as the main safety control	Hazard remains uncontrolled at source	Revisit elimination, engineering and safe-system controls first
Failing to record a near miss	Lost learning and repeated risk	Report according to workplace procedure and include the learning point in reflection

Quality Criteria

A vocational-quality result is assessed against the job specification and the process used to make it. Speed alone is not a quality measure.

Criterion	Evidence of acceptable work	Evidence that further development is needed
Safe process	Controls followed, hot work communicated, tools used within authorisation	Bypassed control, poor hot-metal communication, unauthorised improvisation
Material control	Stock identity and starting section recorded	Unknown or assumed material
Forge management	Appropriate heat achieved with controlled fuel and reheating	Unnecessary idling, excessive scale, overheated or burnt material
Tool control	Tongs grip securely; hammer blows are controlled and appropriately placed	Slipping stock, repeated edge strikes, unstable tooling
Dimensions	Critical dimensions fall within the instructor's stated tolerance	No measurement plan or avoidable dimension drift
Geometry	Taper, bend and alignment match the drawing, sample or template	Twist, kink, uneven section or asymmetry beyond the allowed criterion
Surface	No unacceptable cracks, cold shuts, deep hammer marks or evidence of burning	Defects compromise function, appearance or safety
Resource efficiency	Stock allowance, fuel use and number of heats are reasonable for learner level	Excessive offcuts, idle heating or repeated corrective heats without a plan
Reflection	Specific evidence is used to explain what worked, what changed and what happens next	General comments without evidence or a next action

Sustainability in the Forge

Sustainable blacksmithing combines material efficiency, energy awareness, durable work and responsible waste control. It must never mean reducing ventilation, extraction, PPE, cooling breaks or other safety controls.

Material efficiency begins with accurate stock calculation. Choose a starting section and allowance that provide enough metal for the form without creating unnecessary offcuts. Keep labelled reusable offcuts separate from unknown scrap so traceability is not lost.

Energy efficiency means heating only when the job and operator are ready, maintaining a fire or furnace appropriate to the stock, reducing unnecessary reheats through better sequencing, and shutting down equipment according to the site plan when it is no longer required. A well-maintained forge, blower, refractory lining and extraction system usually supports both safety and energy performance.

Waste control includes segregating steel scrap, clinker, spent abrasives, coatings, oils and other wastes according to the workshop procedure. Do not wash contaminated residues into drains. Recycle clean ferrous scrap through an approved route.

Product longevity is also sustainability. A well-proportioned hook, fitting or architectural detail that works correctly, resists corrosion appropriately and can be repaired has lower material impact than a poorly made item that is discarded early.

Procurement can consider recycled content, verified grades, local supply, durable tooling and supplier environmental data where these do not compromise the technical specification.

Authentic Vocational Examples

A blacksmith making a set of architectural hooks may first forge one approved sample, then use a template and callipers to keep a batch consistent. If the sample needs three heats but later pieces regularly need six, the smith does not simply work faster; they investigate stock allowance, fire condition, hammer choice, sequence and measuring points.

In heritage ironwork conservation, existing material may be historically significant and its composition uncertain. The correct response is not to apply a modern forging routine automatically. The blacksmith works to the conservation specification, records interventions and seeks specialist advice where material identity or historical significance affects the process.

In artistic metalwork, controlled variation can be intentional. A hand-forged texture may be part of the design, but cracks, unplanned sharp edges, poor fixings or inconsistent dimensions at a mating joint are still quality defects. Craft quality means knowing which differences are designed and which are process errors.

Process photo essay: With workplace permission, produce six annotated photographs showing planning, tool selection, supervised heating, forging, measuring and final inspection; no photograph should require you to step into another person's hot-work zone.
Blacksmith interview: Interview a practising blacksmith, forge technician or vocational instructor about how they manage material identity, reheating decisions, hot-metal communication and quality checks, then compare the answers with this module.
Fuel and waste audit: Observe one approved training session and record idle heating time, clean steel offcuts, mixed waste and avoidable reheats, then recommend two resource improvements that do not weaken safety controls.

Advanced

Repeatability study: Under supervision, produce or analyse a short batch of comparable components, measure agreed dimensions, identify the largest source of variation and propose one process change to improve consistency.
Forge risk-control review: Using the local risk assessment as the primary source, map each significant forge hazard to elimination, engineering, organisational and PPE controls, then identify one control whose effectiveness should be checked more closely.
Design-to-make project: Develop a small artistic or architectural forged component from sketch to drawing, stock allowance, supervised manufacture, inspection and resource review, with the instructor approving the material and process before hot work begins.
Expert-review video: With workplace permission and a competent supervisor present, create a short video explaining a completed practical project; focus on decisions, controls, quality evidence and reflection rather than presenting the film as a standalone forge-operating tutorial.

Learning Assessment

Risk-control reasoning: Given a scenario involving smoke escaping from a forge hood, explain which work should stop, which people should be informed and why PPE alone would not be an adequate response.
Material decision: Compare identified low-carbon steel with an unknown plated scrap bar for the practical project and justify the technically and legally defensible choice.
Process diagnosis: A learner needs twice as many reheats as expected and the work carries heavy scale; propose three possible process causes and the observations needed before changing the method.
Quality transfer: Explain how the quality criteria for one hook would change when making a batch of twenty components for architectural use where repeatability and fit become critical.
Sustainability judgement: Evaluate two ways to reduce fuel use and distinguish a genuine process improvement from a change that would compromise ventilation, supervision or material quality.
Communication under risk: Write a short response to a near miss in which a dark hot bar was left on a normal bench, including immediate control, reporting and a prevention measure.
Reflective improvement: Use measured dimensions, a photo or tutor feedback from your project to identify one technical strength and one next-step practice goal that can be checked on the next piece.

Evidence of Learning

Evidence area	Strong evidence may include
Knowledge	Correct explanation of forge system, workability, scale, material identity, risk hierarchy, current UK authority roles and quality criteria
Practical skill	Safe supervised work holding, controlled hammering, planned reheating, measuring between heats, correct hot-metal placement and orderly close-down
Product	Finished component meeting the instructor's drawing, sample or template within stated quality criteria
Documentation	Material record, risk-control check, measurement notes, photos where permitted, waste or fuel observations and final inspection
Professional behaviour	Clear communication, stop-work judgement, respect for authorisation limits, care of tools, constructive use of feedback
Reflection	Evidence-based explanation of what happened, why decisions were made and what will change next time
Transfer	Ability to apply the same plan-control-make-check-reflect cycle to a different forgeable component without assuming that material, tooling or safety arrangements are identical
