Original wax positive - ready for molding.
The first layer of plaster/silica/water mix is applied reasonably thin and a collar is created around the base.
A fibreglass 'skin' is placed around the first layer. It needs to be rough, so that the next layer can adhere properly.
This is the 3rd layer. A 4th layer was then created using a combination of plaster, silica, water and ludo to make the mold as strong as possible.
Final layer includes grog instead of ludo. It's important to ensure the top is level, so that the mold will sit evenly in the kiln.
The wax is now being steamed out of the mold in preparation for the kiln. Almost 7 kilos of glass will be melted into the cavity to make this piece.
Mold is in the kiln (pictured left), with glass positioned above in a terracotta crucible and ready to melt into the cavity..
