I have been trying to make sculptural pieces but have encountered several cracks even though I keep annealing as I go along. I thought that if I could take a piece after annealing directly out of the furnace at the high temperature and directly plunge it into the flame I could heal cracks more quickly and efficiently. For that I'd need to use heat resistant gloves.
So my questions are,
Will this method help in sculptural work, especially in healing cracks?
And what glove should I buy that can protect my fingers when working with boro glass at annealing temperature?
Hope someone out there can help!
