Working Notes

Hues of shift colours change depending on the light source (natural, incandescent, LED, or fluorescent) and sometimes thickness, regardless of whether they have been fired or not. 

Finished work will have the same colour shift properties found in the cold glass. When used in small amounts, the shift between green and pink in this rare-earth glass is subtle. The colour shift becomes more dramatic in thicker applications and depends on the light source. In mixed types of light, it appears to be brown. Not a striking glass.

Fusible / Bullseye-compatible.
