I don't have time to search right now through more threads. I am so frustrated. Looking for sand without silica. I was told somewhere contractors sand. All say "may contain silica". The play sand packaging cannot be read, the lettering is so poorly printed. So I'm guessing not the QUICKRETE brand. What brand of sand do you use and where can I find it? I've been to Home Depot & Lowes.
Sand is pure silica, as is glass. The thing you are trying to avoid is the very fine particles that can become airborne and then inhaled. I would say play sand is the "safest", who would want to get sued for causing lung disease is children.
Are you using this for chicks in a brooder or a run for outdoor chickens?
