Hello all im new to lampworking and boro Ive made a couple of items and i prob know the answer to this but i had different expertations of boro.
Ive made 2 items with boro and cooled them with vermulicite so i could batch anneal them. I made a implosion pendant and a marble. Both items when lifted from the verm. had cracks in them. Now im not sure if i can fix them the pendant exploded when i tried to very slowly reheat it. The marble i havent tried yet.
Here is a picture of the marble.

I am unsure why these are cracking. If you have any ideas please help. I do know that the pieces should be annealed right away but i do fusing projects also and sometimes my kiln is in use. and while im waiting for the kiln my pieces crack.
