Bullseye Petal Pink Frit (style 000421) is 90 COE fusible frit, crushed glass in graded grain sizes for casting, layering, shading, and decorative surface work.
Cold characteristics Bullseye writes these notes for the sheet form of this color; the same glass is used to make this product.
Uniform color.
Working notes No color shift. May not be suitable for kilncasting when using a plaster/silica mold, or similar refractory, combined with high temperatures for an extended period. This combination may result in a glass object with a heavily devitrified and sometimes crazed surface. Testing recommended. We have observed successful kilncastings with 000421 in open-faced, ceramic molds with separators ZYP/boron nitride or Bullseye Shelf Primer. We have also observed success using 000421 in processes where heatwork exceeds the test for compatibility without the use of a plaster/silica refractory mold. Bullseye Compatible.
Reactions This color is not reactive. It can sit next to any color without forming a reaction line, so it works well as a dependable base or background. See the Reactive Potential of Bullseye Glass chart to find the colors that do react.
Using the frit Bullseye frit is sold in grain sizes from powder to coarse. Powder gives soft, even color and shading, fine and medium build controlled texture and coverage, and coarse gives bold flecks of color and fills for casting and pattern bars. Choose the grain by the effect you want and the fired thickness of your piece.
Fusing and compatibility Tested compatible with other Bullseye glass. When you combine it with glass from other makers, matching COE alone does not guarantee compatibility, so fire a small test tile first.
