    vocational

    Chasing is a metalworking technique where the front surface of a precious metal object is worked with punches and hammers to create low-relief designs. This unit focuses on interpreting technical drawings and specifications to produce complex chased items, such as decorative panels, hollowware, or jewellery components. Learners must master precise tool control, material properties of precious metals, and surface finishing to meet professional standards.

    AIM Qualifications Level 3 Diploma in Precious Metal Engraving (QCF)
    AIM Awards Level 3 Diploma in Silversmithing (QCF)

    Topic Overview

    The AIM Awards Level 3 Diploma in Silversmithing (QCF) is a comprehensive qualification designed for individuals seeking to develop advanced skills in the design, fabrication, and finishing of silver objects. This diploma covers a wide range of techniques including sawing, soldering, raising, forging, and surface decoration, enabling students to create intricate and high-quality silverware. The course emphasizes both traditional craftsmanship and contemporary design, preparing students for careers as professional silversmiths, jewellery makers, or for further study in higher education.

    Within the Manufacturing & Engineering sector, silversmithing represents a specialized area of metalworking that combines artistic creativity with technical precision. Students learn to work with sterling silver and other precious metals, understanding their properties and how to manipulate them through various processes. The qualification also covers essential business and professional practices, such as costing, marketing, and health and safety, ensuring graduates are well-rounded practitioners capable of working in workshops, studios, or running their own businesses.

    This diploma is structured to build competence progressively, starting with fundamental skills and advancing to complex projects. Assessment is through practical assignments and a portfolio of work, demonstrating the student's ability to plan, execute, and evaluate their creations. By the end of the course, students will have developed a strong foundation in silversmithing techniques, a keen eye for design, and the confidence to produce finished pieces that meet industry standards.

    Key Concepts

    Core ideas you must understand for this topic

    • →Annealing and work hardening: Understanding how to heat silver to soften it for shaping, and how to control work hardening to achieve desired strength and form.
    • →Soldering techniques: Mastery of hard and soft soldering, including flux application, heat control, and joint preparation for seamless joins.
    • →Raising and sinking: Forming three-dimensional shapes from flat sheet metal through systematic hammering and planishing.
    • →Surface decoration: Techniques such as chasing, repoussé, engraving, and patination to add texture and visual interest.
    • →Design and development: The process of sketching, modeling, and prototyping to translate ideas into finished pieces, considering ergonomics and aesthetics.

    Learning Objectives

    What you need to know and understand

    • Understand how drawings and specifications are used to produce chased work, Understand how to use tools and materials correctly to produce chased work, Be able to produce complex chased items
    • Understand how drawings and specifications are used to produce chased work, Understand how to use tools and materials correctly to produce chased work, Be able to produce complex chased items

    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for demonstrating accurate transfer of design specifications from working drawings onto the precious metal surface, ensuring correct scaling, placement, and proportion.
    • Expect clear evidence of correct tool selection and handling; for example, using a lining punch for outlines and a matting punch for background textures, with consistent impression depth.
    • Require evidence of effective use of a pitch bowl or lead block to support the workpiece, preventing distortion and allowing clean, crisp chasing results.
    • Award credit for accurately translating 2D design specifications into a planned chasing sequence, evidenced by clear tool progression marks on a test piece.
    • Credit for demonstrating appropriate selection and safe handling of chasing punches, hammers, and supporting materials (e.g., pitch consistency) to suit metal gauge and design intricacy.
    • Award credit for producing a complex chased item that exhibits uniform depth, smooth contouring, and crisp detail without surface damage or distortion to the host object.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Carefully study the supplied technical drawings and specifications before starting any practical work; highlight critical dimensions and note any tolerance requirements.
    • 💡Practice smooth, rhythmic hammer blows to achieve uniform punch marks; inconsistent striking leads to a visible, unprofessional finish.
    • 💡Document your annealing cycles and tool choices in a log to demonstrate understanding of material behaviour and process control, which can be valuable evidence for assessment.
    • 💡Always create a chased test strip to calibrate your hammer force and punch selection before working on the final piece; submit this as supporting evidence of planning and refinement.
    • 💡Use resist markers or layout fluid to clearly transfer your design and periodically check alignment against the original drawing to avoid cumulative error in complex patterns.
    • 💡Document your working process with annotated photographs or a witness statement to substantiate your decision-making, tool choices, and troubleshooting for the assessor's evaluation.
    • 💡Pay close attention to health and safety documentation. Examiners look for evidence that you can identify hazards and implement control measures, such as proper ventilation when soldering and safe storage of tools.
    • 💡In your portfolio, include clear photographs of each stage of your work, with annotations explaining your decisions and techniques. This demonstrates your understanding and reflective practice.
    • 💡When presenting finished pieces, ensure they are thoroughly cleaned and polished. First impressions matter, and a well-finished piece shows attention to detail and professional standards.

    Common Mistakes

    Common errors to avoid in your coursework

    • Misreading drawing dimensions, leading to asymmetrical or disproportionate chased designs that fail to match the intended specification.
    • Incorrect annealing frequency: either failing to anneal sufficiently, resulting in metal cracking, or over-annealing, causing grain growth and surface blistering.
    • Using a chasing hammer with excessive force, which can cause the punch to slip and mar the surface or create unwanted deep indentations.
    • Over-working the metal by repeatedly re-chasing the same line, leading to thinning, work-hardening, and potential cracking, especially in fine silver.
    • Failing to secure the workpiece adequately in the pitch, resulting in movement, inaccurate chasing, and uneven impression depth.
    • Neglecting to regularly re-anneal the metal during extensive chasing, causing it to become brittle and resistant to further deformation, risking tool slippage or breakage.
    • Misconception: Silversmithing is only about hammering metal. Correction: While hammering is key, silversmithing also involves sawing, soldering, filing, polishing, and many other precision techniques that require a broad skill set.
    • Misconception: Silver is too expensive to practice with. Correction: Students often start with copper or brass to develop skills before moving to silver, reducing costs while learning essential techniques.
    • Misconception: Soldering is just melting metal together. Correction: Successful soldering requires careful cleaning, proper flux application, and precise heat control to avoid melting the workpiece or creating weak joints.
