Ever wondered how some jewellery has the most amazing intricate details? And think to yourself how have they cut out all of that detail? And how have they made that object 3D?

Well the answer most probably is ‘Lost wax casting’.

is making a wax model, molding it in plaster investment, burning out the wax in a kiln, and then filling the void with molten metal. The wax model is lost, but transformed into metal, like sterling, gold, etc. This video shows attaching the models to sprues, investing them in steel flasks, starting the burnout, centrifugal casting, cutting off and grinding off the sprues, and polishing with a tumbler, I hope you like it.
