I was trying some glass projects and they came in handy..and quick.Occasionally I have to replace glass panes in older sashes..and also when I was building my own cameras I found a need to grind my own glass for viewing screens and cut them to fit large format camera..from 2-1/4'" square up to 11x14".When I looked on ebay and saw the ground glass pieces I needed were going to cost $10 to 40 EACH..plus shipping.. :o ..I figured I better learn to make my own..and did..Used glass is dirt cheap compared to that.I was buying nice picture frames with glass in them in the size and thickness I needed for $1 on sale days. :DB:
I'd buy 11x14 and up and grind my own with carborendum grit between two panes(a 5x7 or so under my hand over a larger piece).The grit was from a cheap rock polishing set from a thrift store..and a lot of elbow grease... :roll:

The secret for cutting and breaking glass is to break it quickly right after scoring. The scored line actually continues to fracture for a few seconds after the score. You can actually see the chips/slivers of glass popping up from the score. Try it, illuminate the glass well from the side and get up close to see the action. I was shown that by the experts. :D


did the expert tell, or show, you that you need to wear safety glasses? ;) :o

Yes they did and gave me a pair when I entered their plant. They gave me a tour and showed me the process of plating glass with silver to produce mirrors(so cool) and showed me cutting, sanding(edging), etching and handling of all kinds of glass related functions.

Thanks for the reminder, I should have said wear safety glasses when watching the glass after scoring.
