Sparkle Gold Mica Powder.
To use, place powder in a frit trough, on a marvering pad or small metal bowl, or you can also use an enamel sifter. Heat the glass until the surface is molten. While the glass is still molten, dip it, roll it or sprinkle it with the Mica Powder. Put the glass back into a gentle flame to flame anneal it. Works on all glass except borosilicate (hard) glass.
Can also be fused between layers or applied on top like a fine-mesh enamel. Sift, brush or air brush. Fire to tack or full fuse.

Available in 3.5 oz (100 gm) bottles.
