PROCESS
Original clay positive
This is a photo of the Gauze Pouch from the 7 Pouch series. It is made from plasteline clay which won't stick to the mold that will be built around it.
Multi-part investment molds
A three-part mold was created using an investment mold mixture. This mixture allows the mold to be placed in a kiln where it is heated to temperatures up to 1700 degrees Fahrenheit. The original clay positive form was removed, leaving a negative impression that will receive the molten glass.
Re-connecting mold parts
All three mold parts are carefully re-aligned and bound with stainless steel wire. Not visible in this image, is the reservoir or opening that is on the underside of this mold. The reservoir is a hole that allows the molten glass a way to get in during casting.
Heavy outer coat
A heavy outer coating of investment mold is placed around the parts to help secure their position during casting. Once again the underside of the mold is where the reservoir is located.
Ready to Fire
This is the mold sitting in the bottom of the kiln, ready to fire. The mold is turned so the reservoir is easily seen on top. Glass will be able to enter into the mold during casting through the opening on top.
The Firing Process
Working with a hot kiln, 1700 degrees Fahrenheit, requires a special suit for protection. Glass is added to a terra cotta pot that sits on top of the mold. The glass becomes molten and passes through a hole in to bottom of the pot, into the mold.
The Finished Piece
This is the finished pouch, cast in a white glass with a wooden inclusion added after. The pouch is called Gauze Pouch and is part of the 7 Pouches collection.
