Lost-wax casting explained — how jewellery is multiplied
One wax, many metals — casting is how designs scale beyond the bench.
Lost-wax casting has worked for six thousand years and still runs the
jewellery industry: carve wax, encase in plaster, burn the wax out, pour
metal into the void.
The sequence
- Model — carved or printed wax, sprued to a tree.
- Invest — plaster flask around the tree.
- Burnout — the wax leaves (lost) in a kiln, leaving channels.
- Cast — vacuum or centrifugal pulls molten metal into every detail.
- Devest, cut off the tree, finish — the casting starts the REAL work:
filing, sanding, polishing.
Why makers care
Casting turns one good design into consistent multiples — the bridge between
craft and production. It also recycles: old silver scrap becomes new pieces.
Where it sits in learning: after bench basics — the
casting course
assumes the foundation ladder
skills. Path: from hobby to certificate.
What students say
“I will use the skills acquired to make pieces for family, friends and of course, myself! If I could get to a point of eventually selling pieces, even better!”
