These colors are leaded and not recommended for food surfaces.
- Kiln needs to be well vented up to 900-1100 degrees.
- If using a kiln that has had other things in it besides glass, such as copper-based glazes and materials it could affect the outcome of the colors. They may turn grey or smoky looking.
- Apply for even coverage.
- If applied too thin it will be grey in color.
- Allow to completely dry before firing.
What types of glass can I use with “G”, “BA”, “GS” “GO” and “GT”s Series colors?
The colors can be used on most types of glass including:
- COE 90
- COE 96
- Float (window) glass.
- They also can be used as an overglaze on glazed ceramic pieces. When planning to use with fired ceramic glaze surface, testing is recommended.
- If the color is chalky or dull then it is probably underfired.
- If color crawls or pulls away from outline then it is probably too heavy.
- Some glass cleaners or not enough ventilation will leave a residue on the glass that can cause colors to be grey.
