I recently bought 7 tubes of this frit hoping that I could do a project that I had in mind. I've had lots of problems with it even though I patiently turned each piece so that the majority of the dichro was on the bottom. It balled up (dichro on dichro I guess) and I haven't been able to do anything with it except to grind off the mounds and humps on the top of the glass. I went to 1550 and held for 20 mins but I couldn't get it to smooth out. Any suggestions? Linda
it has to be capped.
i didnt like working with it, and wont buy it again.
for my purposes, i could cut up a bunch of tiny pieces and get a better result, without grinding and capping.
