[img][/img]I had an idea for a source of coloured glass a while ago, Stained glass! I found a supplies shop locally and was stunned by the variety of colours, even swirls of different colours. The only problem was it was all too thin! 3mm thick to be precise, but there was this one pane which was cast a little too thick and was reduced to £5 for a 12" x 12" x 5mm. yay!
After several tries to make a long Ishi/wintu/desert side notch arrowhead I have managed to make this one! the material is a little thin still, but it will work.
The folk at the stained glass shop said that you can have thicker glass cast to order (any colour) but it will cost about £20 per sheet.Hmmm....I'm tempted, that's a lot of arrowheads....

I'd just get the superglue out and not tell anyone about it Embarassed
That is just too nice a point to waste.

The amount I've dropped and broken recently since leaving the UK and a carpeted floor, to an apartment with a tiled floor.

You're going to have to fling an old towel down onto the tiles. It will give you something soft to aim at.

It also makes collecting up all the shards a bit easier.

[img][/img]This crazy Cahokia arrowhead was from the same piece of stained glass as the long Ishi arrowhead, I think it would make a nice neaklace but it would be a bit spikey.

He he! It would be good to knap a big one. There's an Egyptian flint boomerang in the Ashmolean museum in Oxford, now that would be awesome to make...

Always worth looking at glass first through polarizing lenses. This should reveal whether it will be amenable to knapping or not.

I've not heard of this technique. On a camera a polarising filter make the glass appear transparent, but I wonder how would it help determine knappability?

You whet my interest, could you explain the idea behind it working.
