There' re some clear glasses and dichro that doesn't match. My experience is that round beads are the most forgiving when it comes to cooling. Every other shape is far more susceptible. You said they crack in many pieces. Maybe you can be some more specific.

What glass exactly, what dichro?
How big are the marbles?
How do you put them in the pot?
How do you melt off the last punty?

Sometimes it' s just one little thing and that must not be the kiln.
If the marbles are not that big, let' s say about 10 to 15 mm it' s doable without kiln.
Of course a kiln is required.
But cracking in many pieces makes me suspicious that it might be something else.
