Here is the raw 18k ultra white gold weighed out and ready to be melted.
The wax is put in a flask and then a silica based plaster is poured into it that then hardens. The flask is put into the kiln to let the wax melt away leaving a perfect void of whatever you carved.
The 18k pieces are put into the crucible and a large torch is used to heat the metal.
It takes a couple of minutes but eventually the gold starts to melt together
When the metal is completely liquid the flask is placed in the centrifuge
The centrifuge is spring loaded and counter balanced so it can spin really fast and shoot the molten 18k into the void left by the wax in the silica
Once the centrifuge stops spinning the flask is quenched in water to remove the plaster and release the tree of rings
The finished casting is ready to be cut off and weighed for delivery. Thanks Bob for the amazing casting and Traven for the great pictures!
