Uroboros produces crushed Frit in four grain sizes ranging from Powder (.13mm to .25mm) to Coarse (2.5mm to 7.6mm). All System 96 Frit is made from glass tested compatible to System 96 expansion standards. System 96 is the better expansion fit to most glassblowers' batches, such as "Spruce Pine 87" or "East Bay Special".
Typical uses of the powder range from pate de verre to shading on flat or blown forms. Mixtures of large sizes with dark colors in fine or powder provide particularly dramatic effects. In general, larger sizes tend to fill cavities with less bubble entrapment; smaller sizes blend colors with smoother transitions.
8.5 oz (241 g) jar in your choice of four grain sizes: Powder ($1 extra), Fine, Medium or Coarse.
