Blasting grit Q - nickel slag?

Pretty sure I know the answer to this, but nickel slag-based blasting grit won't work for tanks, right?

I believe the Black Diamond is coal-based, and therefore okay for life in general. This bag is prominently decorated with 'BAD FOR HUMANS' warning labels. The dust is bad, anyway, doesn't mention the material itself.

Very unfortunate, because all the shops that sell grit only have this stuff. Even the ones claiming to sell 'Black Beauty/Black Diamond' actually sell the local brand.

Fairly informative Industrial site. Technical Specifications and MSDS for each product are included in linked tabs.

Way more heavy metal in the nickle blend

Nice link, and thanks for the confirmation. I ordered some Flourite Black gravel last night instead. Shame that it's so expensive comparatively (10x).

Hopefully this will help someone else not waste a lot of time driving to places claiming to sell Black Diamond.
