October Podicle

Transforming raw metal into a finished piece of jewellery is a complex process that calls for exceptional skill, artistry, and patience. Whether it is a meticulously handcrafted ring or a carefully produced design, the craftsmanship involved goes far beyond what meets the eye.

In GT Podicle #24, David and Jane discuss the various jewellery manufacturing techniques, focusing on wax carving, the lost wax casting process, and methods for mass-producing jewellery using rubber and silicone moulds. They also explore the history, and essential tools required for wax carving, the step-by-step process for converting a wax model into a precious metal piece, and the steps needed to prepare a metal model for moulding.
