Abrasive for sandblasting

^^ that's exactly what I did.

If you're going to crush your own glass aim for about 3-4 times the size of sugar - and get some good gloves

That sounds a bit coarse for the DIY type pots. Once crushed it's perfectly safe to handle

I've got a YouTube video somewhere, I'll see if I can find it.
