I have a 50lb bag of black diamond blasting sand around. I think I bought it initially intending to use it as an aquarium substrate.
I was wondering if it would be safe to use in a cp potting mix? It is primarily coal slag.
Here is a link to the MSDS:

Other than material my only other concern would be whether the sand would damage roots. For its intended use I believe it is designed to be somewhat sharp?
