    I'd guess the heavy teal is causing the problems.

    I've had pretty good luck with tag heavy teal. it could be the opaque purple also. Id switch up both colors and see if your still having the problem, also on second thought that white is questionable also.

    heavy teal i've also had decent luck with, but much like indigo adventurine (Northstar) and Blue Stardust (TAG) it seems to need to be heavily oxidizing flame, any amount of reduction at all seems to cause checking.

    i say "seems to" because i honestly have no idea if a slightly reducing atmosphere was the culprit when i did have checking issues, or to put it the other way, idk if it was the heavily oxidizing flame that kept it from checking.

    good luck!

    I believe heavy teal is a chromium color so if you encased it I would blame that. But the striking white also has a history of being somewhat incompatible with other colors and random cracking, I've heard this from a few people already. I've had pendants backed in striking white go pop for what seemed like no reason. It's probably the last white I would grab for these days, except for maybe jade white.

    don't forget about the trusty stringer test/compatibility test...

    color on one side, clear on the other, pull stringer, see if it bends. the more it bends the more likely it will be to crack.

    if you had issues with certain colors, try the test with those, instead of clear...or maybe multiple tests...

    although i believe an actual "check" would or could happen within a single color, ie chromium colors

    just don't forget this place.

    the melting pot is a boat load of info and tips.

    You may have to wade through the BS but it's worth it. and if you ask questions usually people will answer.

    Don't forget about the lampworking books. they have marble tutorials in there and guidelines on how things could or can be done. Vortex marbles are one of them.

    Hands on practice will beat the pants off almost any other teacher, or lessons with someone telling you the ins and outs
