My studio has been a project in the making for over 5 years. When I decided to pursue glass art full-time, I made many purchases and outfitted my place with all the essential tools and equipment that would allow me to produce professional quality art.
I use both COE90 and COE96 glass and frit in my studio, but am very careful to make sure that they reside in separate locations. If they were to get mixed together in a project, the incompatibilities could result in pieces shattering once out of the kiln.
