One danger of firing marbles, powder and chunks of glass (I've
experimented a lot with all three) is that when they pool in the bottom
of a pot, and interesting cracks appear (usually), there are often
microscopic shards of glass along those cracks. Run a finger along one
and you get a painful wound and a piece of tiny, almost invisible glass
jammed into your finger. Eeeeoooowwww!
I've never had the glass melt through clay anywhere, at all, and I've
fired glass at both cone 6 and 10 inside of pots, powdered and
sprinkled, here and there. Mostly it just melts and flows and usually
doesn't look very attractive.

And isn't there a danger using glass in chunks, like marbles..in that, if it
isn't properly annealed, it may, one day, just blow up? ...just asking...

Not blow up, generally - it's seldom laid
in that thickly. More like, crazes like crazy!
