I'm not the best glass cutter in the world, and I tend to break more than I make, so I really wanted to find out the best way to cut the thin glass.
I've cut the 1mm glass before with a handtool cutter with the little wheel on the end but I started by pressing a bit hard and getting big starburst messes. I also made the mistake of going back over the line but often you get 2 lines then and the break is just wrong.
Apparently, using a scriber with a tungsten-carbide tip is the best option for thin glass. Somebody suggested dipping the tip in light oil before scoring, to get a nice clean line.
Unfortunately, the hardware guy here has never heard of a 'scriber' (I don't know what they call it in Irish!), so I've just thrown my hands in the air yet again and ordered one from ebay. I never needed to leave the house after all!
I'm going to try this on some cheap framing glass first and maybe I'll try the hot water trick, Francios.
