Question about getting a clean break on a 24 inch tube
I was working on a big vase yesterday and needed to cut a 24 inch tube of cobalt blue glass. Figured I'd score it and tap it like normal, right? Wrong. Spent almost three hours trying to get a clean break without it running or chipping. Tried heating the score line with a small torch, cooling it, everything. Finally got it after my fifth try by using a really light touch on the initial score and warming the whole tube in the garage for an hour first. Anyone have a better method for thick color tubes?
