The Use of Float Glass Frits vs. Powders

I originally started out using float glass compatible powders (vs. larger sized frit) in the bottom of my plaster/silica molds. Even though I allow my molds to dry out before firing, the powders seemed to stick more to the glass and created a film I did not like. The white powder (non-lead) created most of the problems. It required a lot of sanding to even out the finish. I switched to using small colored frit instead and the results are much better. This compatible frit can be purchased from companies like CRLOO and Sundance Art Center.

I also have been adding a secret "ingredient" to my castings that will be revealed nearer to the time of the final park installation.

I will be sandblasting a lot of the castings in the next several weeks and will post photos of that process.
