Bullseye frit powders are made from crushed, screened, and magnetically cleaned Bullseye compatible sheet glass. Use frit in frit tinting, kiln-casting and related techniques, or add decorative splashes of color in fusing projects. Frit comes in a durable 4 mil resealable bag. The hues of "shift" colors change depending on the thickness and/ or lighting of the piece. *This color will mature to target color when fired.*
