The first part of the glass casting workshop looked at moulding wax and creating a mould for the glass. The second part of the glass casting workshop worked with the cast class and hand grinding it. First step was to soak the plaster mould to weaken it and get the glass out. We were then able to break off some of the unwanted glass in a safe and controlled environment. To get rid of the larger, rougher edges, we used the technique of glass grinding with silicon carbide by hand (YouTube link). This was an intensive and very noisy process using grit and water on top of a thick piece of glass, and then grinding the object against this surface. Not only did I flatten off the bottom, but I also curved the grinding round so that some more of the bits that stuck out were smooth and in line with the bottom and the side of the design. The final product was a flat bottomed platypus/duck in a canoe.
