I've been checking waxes at a bronze casting foundry in North Wales today. I sculpt mainly in clay. The foundry makes an exact replica of my original in wax. This is known as the 'lost wax process' This wax is encased both inside and out with plaster. Molten bronze is poured into the plaster casting and the wax melts out through feeds and is 'lost', the bronze setting in its place. I then treat the sculpture with acids in a process called patination in order to colour the surface of the bronze. The whole casting process takes 3 to 6 weeks.
