Because confetti needs to be so heavily saturated with colour, some of the opalescent colours tend to devitrify. The pink is particularly prone to devitrification. There are several ways to prevent this:
- cap (which can lead to bubbles),
- add a devitrification spray, or
- cover with clear powder or frit.
Covering completely with a fine layer of powder gives the most even result. Using frit can provide a speckled appearance that is useful in some circumstances.
This tendency of pink opal to devitrification applies to all formulations – Bullseye, Uroboros, S96 and float.
