Sv: Cob: Glass Blocks/Bricks

[kajchr]

I know an easier way of cutting bottles: You take a piece of yarn and tie
it around the bottle in the place where you want to cut it. Then you wet
the yarn in spirit or alkohol, light it, and is soon as it burns out you
put the bottle in cold water. Voila! Now all you may have to do is tap the
bottle slightly to make it come apart, and sand the sharp edge if you want
to. I don´t know if there is a max. size to the bottles that this method
works on but it works fine on wine bottles.
