Amy’s notes: This frit was very versatile and worked great with the 104 COE backdrop. I did have some issues with it when trying to make too many spacers on one mandrel. I think it may be a bit on the sensitive side to thermal shock. I also don’t recommend using it with the K100 Leaded Clear, as the lead and red react to produce more of a brown colour (unless that’s what you are looking for!) I used Kugler K110 Unleaded Clear and Uroboros Clear (both in 96 COE) for encasing/otherwise embedding the frit in the glass (such as with my swirly spacers), and Effetre/Vetrofond 104 COE for many variations of frit on the surface. No issues with compatibility cracks or thermal cracks, except when I tried to make 12+ spacers on one mandrel! (bad habit of mine that I can usually get away with).
