Learning Objectives
What you need to know and understand
- Be able to prepare for the implementation of engraving processes., Be able to produce engraved surfaces.
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating correct selection, preparation, and secure mounting of gravers, scorpers, or other engraving tools appropriate to the metal and design.
- Assess the quality of surface preparation, including cleaning, layout transferring, and the application of a suitable background finish (e.g., matting, bright cut) prior to cutting.
- Evaluate the consistency of line depth, uniformity of pattern, and overall sharpness of the engraved image, ensuring no slips or unwanted marks.
- Check for evidence of controlled hand positioning and tool angles throughout the process, with final work free from burrs and requiring minimal remedial fettling.
Assessment Guidance
Guidance for achieving higher grades
- 💡For portfolio evidence, photograph key stages: tool sharpening setups, test cuts on practice plates, the in-progress engraving, and the final cleaned piece, annotated with reflective notes.
- 💡When producing engraved surfaces for assessment, use drawing or transfer methods to clearly define the design before cutting; this demonstrates planning and precision.
- 💡Explicitly reference health and safety measures in your write-up, including extraction for metal dust, eye protection, and safe handling of sharp tools, to align with City & Guilds assessment criteria.
- 💡Showcase versatility by including examples of different engraving styles (e.g., banknote, bright cut, or relief) and explain the tool modifications required for each.
- 💡Always use correct technical terminology in your answers, such as 'fineness', 'annealing', 'flux', and 'solder'. This shows the examiner you have a deep understanding.
- 💡For practical assessments, plan your work sequence before starting. This demonstrates organisational skills and helps avoid mistakes like using the wrong solder.
- 💡When answering questions about hallmarking, quote specific legal details, such as the weight thresholds and the marks required, to gain full marks.
Common Mistakes
Common errors to avoid in your coursework
- Students frequently fail to adequately secure the workpiece in an engraver's block or vice, causing movement that leads to misaligned cuts and potential damage to the piece.
- Incorrect sharpening of gravers, particularly the wrong facet angles or uneven heel, results in poor cutting action, skipping, or digging into the metal.
- Overlooking the need to anneal work-hardened precious metals before engraving, which can cause difficulty in cutting and increase the risk of tool breakage.
- Applying excessive force to compensate for dull tools or hard metal, leading to loss of control, inconsistent lines, and premature fatigue.
- Misconception: Hard solder is always better because it is stronger. Correction: Solder type is chosen based on melting point, not strength. Using hard solder for all joints can cause previous joints to fail when heated again.
- Misconception: Hallmarking is optional for small items. Correction: The UK Hallmarking Act 1973 requires hallmarking for items above certain weight thresholds (e.g., 1 gram for gold, 7.5 grams for silver), regardless of size.
- Misconception: Annealing is only for steel. Correction: All metals, including gold and silver, work-harden and need annealing to restore ductility during shaping.
Revision Plan
How to revise this topic in 1–2 weeks
- 1Week 1: Focus on theory – revise metal properties, soldering, and hallmarking. Create flashcards for key terms and fineness values.
- 2Week 2: Practice practical skills – set up a small project like a silver ring, focusing on soldering sequence and annealing. Record your process for portfolio evidence.
- 3Week 3: Attempt past exam questions under timed conditions. Review mark schemes to understand what examiners look for.
- 4Week 4: Consolidate – revisit weak areas, practice stone setting on a dummy piece, and memorise hallmarking marks.
Exam Question Types
How this topic typically appears in the exam
- 📋Multiple-choice questions on metal properties and hallmarking – read each option carefully, as some are designed to trick you.
- 📋Short-answer questions requiring definitions of terms like 'annealing' or 'flux' – be precise and use technical language.

Command Word Expectations (CITY & GUILDS LIMITED)
What examiners look for when using specific command words in this specification
Provide a detailed account of a process or concept, including reasons and mechanisms. For example, 'Explain why annealing is necessary' requires you to describe the process and the science behind it.
Show your working and give the final answer with units. For example, 'Calculate the mass of gold in an 18ct ring' – you must show the formula and substitution.
Weigh up pros and cons, or compare methods, and give a justified conclusion. For example, 'Evaluate the use of CAD/CAM in jewellery making' – discuss advantages and disadvantages and state your opinion.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A jeweller needs to make a ring from 18 carat gold. The ring weighs 12 grams. Calculate the mass of pure gold and the mass of other metals in the ring.
- 1.Step 1: Identify the fineness of 18 carat gold, which is 750 parts per thousand.
- 2.Step 2: Calculate the mass of pure gold: 12 g × (750/1000) = 9 g.
- 3.Step 3: Calculate the mass of other metals: 12 g - 9 g = 3 g.
Question: Explain the process of annealing silver and why it is necessary during the manufacturing of a silver bangle.
- 1.Step 1: Define annealing: heating the metal to a specific temperature and then cooling it slowly to soften it.
- 2.Step 2: Explain why it is necessary: working (e.g., bending, hammering) causes work-hardening, making the metal brittle and prone to cracking.
- 3.Step 3: Describe the process: heat the silver to a dull red colour (around 600°C) and then quench or allow to cool, which relieves internal stresses and restores ductility.
