Breaking quartz

[oldbrundogg]

Ok I know I should be able to think this one through myself, but just got off work and I'm tired. I've watched everybody use their rock smashers. I have my post driver almost ready to go but some of the rocks I want to start with are fairly large 10 to 12 inchs and maybe 5 inches wide or thick should I wrap them up in something to break them down into more manageable size??

Yup, just get some old towels or blankets, wrap them up and smash em.
Towels wont last long like this, you could put a 2x4 over them to help from ripping up the blanket or towel with every smash.

I found that putting them in a hot fire makes even the toughest rock crumble in your hand, be careful of fumes though. Not sure how safe this method is.
