Introduction
This project was part of a class that I took at Mass Art, Form to Fire. I decided to pursue an independent project in lost wax casting. For this project, I did training for the Hotshop, the forge, sheet metal bending, spot welding, silicone molding, wax casting, plaster mold making, and working with plaster blow molds in the hot shop.

The Mass Art Industrial Design Lab Tech, Zach, taught me how to cast silicone molds. We created sprews out of foam to screw into the bottom of the gourds. The gourds and sprews were attached to the wood at the bottom of the tube to stop them from floating while the silicone cured.
Once cured, the pumpkins and foam were removed and the silicone molds were used to cast hot wax into.
The resulting wax casts. I learned that I needed to make the sprews slightly wider. So I used excess wax to widen the sprews to the size of a film canister to make it possible to fit glass into the blow molds.

Olin shop professor, Dyllan, taught me how to make plaster sillica molds with the wax. I fastened the wax to wooden planks which were weighed down by stock metal so that the wax did not float. This was a process that needed a well ventilated space.
I used carpet steamers to melt the wax out of the 6 plaster silica molds. This was a slow process. I created a steaming tent out of think plastic bags that clay usually comes in. I now have 6 plaster blow molds, that glass can be blown into.
I added welded sheet metal to contain the plaster under pressure when we used the blow mold with glass.
