Steider Studios offers kiln rentals and retails mica and Bullseye Tested Compatible glass as well as tools and other supplies (below) for working with glass. Linda is an Authorized Dealer of Kemper Tools.
We've chosen to offer the following colored micas because we've had good, consistent results in fusing them to glass. After testing hundreds, we found the majority of colored micas lost color or left unpleasant residue instead of color. We use dry mica, sifted directly onto sheet glass, or mix it with powdered glass in varying ratios and sift directly onto sheet glass.
Mica offers different results on different colored backgrounds. Choosing to clear cap is another option as the color can drastically change when clear capped.
We suggest you make a small test when you receive your colored micas to see how they react with your glass, firing conditions and other variables at your studio.
Mica will fuse to glass it's actually touching, but not to itself, so after fusing, you'll brush off the excess mica that wasn't clear capped.
Please note the following mica color shifts we've observed:
Variations of color can be achieved by mixing mica with a variety of glass powder (frit size 08) colors, including clear. Try mixing in ratios of 2 glass powder to 1 mica, then 4 glass powder to 1 mica, then 6 glass powder to 1 mica, etc. Many interesting effects are possible.
