Cynthia - I really liked your example of the mica powder powder on amber transparent capped with clear. How did you do it? Did you airbrush the mica or just sprinkle it and did you fire it before you capped it ? and at what temperature. I'd really like to give mica's a try but my first attempts seemed to disappear into the glass.
Best regards
Linda

No airbrushing on these pieces. I suspend the mica in alcohol and paint or pour it where I want it. For contained spaces or hard edges I would airbrush using stencils. Cap and fire to full fuse (no prefire) with a bubble squeeze firing to help reduce the amount of air you trap.

When I took a class with Roger Thomas he said to add a drop of liquid dishwashing detergent to the alcohol and mica to break the surface tension. As he is a former chemist by profession I assume this is significant.
