I'm spending two hours or more rotating marbles in the hottest flame I can get and using marble molds trying to get it smooth and round. I know a lot of the problem is my lack of experience but 2+ hours on each marble seems excessive. I was hoping to start doing production of these so this problem is really concerning me.
I'm attaching a link to a page showing an example of a marble that I had this problem with. For this marble, I wound yellow coloring around the clear, added two layers of dots, and spiraled some colors at the bottom.
Any advice or suggestions you have would be really appreciated!
I had the exact same problem. I was using a Wale Firebird and making inch and a half marbles - for eight months! It was taking me two hours to implode a flower and dot and twirl the back. So I just got a Carlile CC with a foot pedal for the outer flame. The same marble - 45 - 60 minutes now, and the more I get used to the additional heat the faster it will go. But if you are doing this as a hobby, what's the rush?
