Cadmium compounds are utilized in coloring [[borosilicate glass]]<ref>{{cite web|url=http://www.adamschittenden.com/Borosilicate_Glass_Material_Properties.php |title= Borosilicate glass material properties |publisher= Adams & Chittenden Scientific Glass |access-date= 12 April 2019}}</ref> used by artists in [[lampworking]]. The palette is often referred to as "cadmium colors" or "cadmium-based colors" and is marked by uniquely bright and saturated tones not found in other colored glass. Cadmium pigments used in borosilicate have a relatively short history, with the first commercial formulations hitting the market in 2000 under the name Crayon Colors by Henry Grimmett of Glass Alchemy.<ref>{{Cite web|url=https://glassalchemy.com/pages/about-us|title=About Us|publisher=Glass Alchemy|access-date=2018-11-05}}</ref>

Cadmium-compound-containing glass exhibits a characteristically low heat tolerance when melted, and therefore must be treated with caution when lampworking to avoid boiling off of the [[cadmium sulfide]]. CdS has a boiling point of 980 °C (1,796 °F), putting its maximum temperature tolerance as a pigment not far above the working temperature range for borosilicate, which has a softening point of approximately 850 °C (1,562 °F).<ref>{{Cite book|title=Vacuum Physics and Technology|date=1980|edition=1st|publisher=Academic Press|editor1-last=Weissler |editor1-first=G.
