    Picked up an old used siphon sandblaster off Craigslist for relatively cheap. It came with 2 buckets of sand.

    The seller is a garage sale/auction reseller and claimed no knowledge of the blaster or media.

    I believe this is silica sand and if so won't use it except maybe outside in a strong wind and a respirator but if it's not sand I'll still use a respirator but try to reclaim it and re-use it.

    I'm not a sandblasting expert by any stretch of the imagination.

    Can any of you tell for sure if this is sand and not something safer?

    Thanks. 20191203_085701.jpg

    It could be sand, it could be pulverized glass, but whatever you use, body and eye protection is mandatory. If you have it, do you think you're obligated to use it?

    Looks like glass media to me.

    It's easily 100#'s worth. If it's glass that's a little chunk of change I will use.

    I blasted a bit of it for maybe 3 seconds outside and it worked well. I also tried some cheap coarse slag from TSC and it plugged the gun up almost instantly. That's the only media I have on hand. Need to start blasting the underside of the 69 Ranchero soon but it sure ain't worth getting silicosis. I'll make another trip into town and buy some fine slag or get expensive media if what I have is sand and not glass.

    Where respiratory protection regardless of the media that you use. And use a full suite of PPE (Personal Protective Equipment) - that stuff gets everywhere, (take my word for it, just push the "I believe" button on it).

    Way back when, I used a product called "Star Blast", manufactured by DuPont and recommended for sheet metal of the gauges used in auto bodies of our era. And it could be swept up and reused several times.

    Yup, any dust you breathe in, it'll fook up your lungs. Remember, glass is also silica.

    Been blasting enough to ready for paint to let me get the new gas tank installed and new rear brake lines and brakes. Again, tackling small projects over time rather than tearing it completely down and getting overwhelmed.
