Working Notes

Frit size relates to bubble population: In general, when kilncasting with frit in open faced molds and containment systems, larger grain sizes trap larger bubbles. With smaller grain sizes, the bubble size decreases while the frequency increases, creating a hazy or opaque effect from otherwise transparent material. This effect can also be observed when kilnforming with heavier applications of frit and powder.

Clear Iridescent Frit is made of crushed rainbow iridized sheet glass (001101-0031), which has a thin, metallic coating on one side. As frit, the coating is more evident in larger grain sizes (-05, -03), where it has greater surface area. With smaller grains (-02, -01, -08) the coating is not present on each piece of frit due to the nature of the crushing process and the resulting grain sizes.

Irid frit may be used as a design element on sheet glass to create subtle glints of rainbow iridescence; here shown on the surface of a 6mm clear sheet, taken to a full fuse (1490°F, 810°C). The color effects from the pieces of iridescent coating are more noticeable with reflected light paired with a dark background.

Usage suggestions: Use the Extra Large or Coarse Frit in cast tiles or thick cast bowls for subtle, metallic effects. Apply Medium and Fine Frit to sheet glass for a hint of glint. In comparison, effects with powder are even more subtle. When working on sheet glass, iridescence generally has more contrast with darker-valued styles.
