READ THE INSTRUCTIONS!!! Or go online and get some, when trying something new. I’ve been making mirrors this past month. After breaking too many, I finally went online to see how I was supposed to be doing it. Just about everything I was doing was wrong.
To do it right, check http://www.abacaglass.com/how_to_cut_glass.htm. And, you can watch this video http://www.youtube.com/watch?v=6SYDudIujRM. I’m sure I’ll never be snapping the mirror pieces apart quite like this guy, but I can, after a half hour of practice, cut and break a straight line.
I’d like to have other artists send me their tips to post. M
