Neolavendar and Rhubarb powder--color shift?

Postby crocglass » Tue Aug 10, 2010 6:30 pm

I researched the glasstips but could not find the answer to what is in the glass that makes it shift colors under different light conditions. Could someone please explain this? Thank you.

Hi Crocglass,

The colorant in Neolavender 1442 is neodymium, and the colorant in Rhubarb 1859 is praseodymium.
