Hi Guys
Last night I attended a Jewellery Design School open house. I was surprised that casting precious metals such as silver or gold no longer a trend. Instead, the precious metal comes in white clay form, a combination of water element, combining agents and precious metal molecules.
It’s handled just like any dough with water to soften then roll, cut and form to any shape. Almost like kids playing plastercine. Then it’s bake in a normal toaster oven for an hour to harden, to evaporate the water and binding agent.
The last stage, simply brush away the white powdery surfaces to see the pure silver finish. At this stage, it’s pure metal and nothing else.
Wonder this metal clay comes in cast iron type in the market? So next time, anyone in need for casting small replacement parts can approach this way!
Then the harden piece is machined to size.
Need not go through the foundary method, troublesome and costly for those making only a few pieces.
