I make a lot of soft glass marbles in the 30 to 40 mm range. They never get in touch with any metal tools just graphite. I shape the marble in a preheated mold and also melt off the punty this way. And the marble is still in the mold when I put it into the kiln.
And for me it's really important to know the brand of my clear glass and dichro.
As I said before there' re clear glasses that doesn' t match with some dichro.
To rule out certain mishaps you can start series of tests.
I would begin with a solely clear marble then clear and dichro, then clear and different colour glasses and so on.
I'm curious what will be the results.
Good luck!
