Using mica powder in glass fusing makes it possible to create a wide range of metallic effects.
Mica powder and flakes are a mineral that is used commercially, particularly in the cosmetic industry to create products with a glittery appearance.
Mica that is produced for the cosmetic industry is not suitable for glass fusing due to the high temperatures found in glass kilns. The high heat generated will burn the powder away.
Suitable mica powder can be found in glass fusing supply stores.
Glass jewelry as well as more general glass fusing projects can have mica added to produce many metallic design styles. It has been extensively used for glass bowls amd dishes.
