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:

• Amethyst fused directly onto glass remains amethyst; fades to light pink when clear capped.
• Blue fused directly onto glass remains blue atop; strikes to a pale strawberry when clear capped.
• Blue Violet fused directly onto glass remains blue violet; strikes to a very pale flesh tone pink when clear capped.
• Bordeaux fused directly onto glass stays bordeaux; is slightly brighter when clear capped.
• Gleaming Gold fused directly onto glass gleams, but is brighter when clear capped.
• Green fused directly onto glass is dark green and a lighter green when clear capped.
• Mermaid Gold fused directly onto glass strikes to green; remains gold when clear capped.
• Raspberry fused directly onto glass remains raspberry but almost all color burns out to a beige when clear capped.
• Red Violet fused directly onto glass is a pinkish lavender and is a bit darker when clear capped.
• Pewter fused directly onto glass is a pewter silver but almost all color burns out to a pale petal pink when clear capped.
• Verdigris Gold fused directly onto glass remains as is, and when clear capped is brighter.
• Mica Flakes should be clear capped, as they easily flake off and leave a rough texture when fused directly onto glass.

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.
