Black Beauty... Is what we used, actually a lot of places don't even allow you to use sand anymore. Geez....That brings up bad memories of choking on that crap! Coughing like crazy! Worked for a place that we blasted and painted heavy equipment with nothing more than a paper mask and a face shield. The pot had to be moved with a backhoe or big fork lift,had a tag along diesel compressor we would have pallets of silica sand siting there lined up dumping it by the bags when it was empty, sand in places on your body you had no idea how it got there, arms and any exposed skin tore up from it bouncing back or bad hoses or connections!

I was young and dumb and didn't know any better to tell them to pound sand! It took a toll on my lungs for sure! I'll pay for that in a few more years!

At one point towards the end of me working there they switched to slag! That was a huge difference, still got the rust clouds though! But the blasting abrasive wasn't as dusty.
TNmountains...That makes me laugh! Every time my dad gets new coal for his forge he cooks it(or whatever he does, I thought he was making coke to use) the last time I was up there, he had the area full of this choking smoke! But.....He's also one of these "we are going to be under water if we don't stop pollution guys" Go figure!

Argue with me about how we have to do our part to stop global warming....But choke the place for a half mile to pound out a nail or curly thing to hang a plant on?
