This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
This unit standard will be useful for persons who are required to demonstrate theoretical and practical knowledge to manufacture jewellery.

Learners credited with this unit standard are able to:
  • Understand and describe re-crystallization after melting and annealing.
  • Understand and describe the physical and mechanical properties of cast and cold worked metal.
  • Understand and calculate precious metal alloys.
  • Understand the theory and practice of rolling, hammering, fluxing, soldering and polishing.
  • Understand the causes and prevention of porosity.
  • Demonstrate knowledge of annealing, hardening and tempering of carbon steel.

    The skills, knowledge and understanding demonstrated within this unit standard are essential for social and economic transformation and contribute to the upliftment and economic growth of the mining and minerals sector.

    This unit standard is intended to promote general skills, knowledge, description and understanding metallurgical principles for jewellery manufacture in the mining and minerals sector in order to ensure knowledgeable and informed workers.
