Sno White, 9995
White is a necessary and ironically very difficult color to make in glass. Tin based whites have been made in the past but have not been very successful. We wanted the rich deep white associated with tin so we spent many years drilling down on the final formula. Today's Sno White, 9995 is the highest saturated white on the borosilicate market.
Working Tip: Heat slowly to raise the core temperature. Once the heat base is established, this color can be worked very hot and any air bubbles that popped during the preheat will smooth out. Getting this color white hot will cause excessive gas release that can not be repaired and should therefore be avoided.
