Play sand safe for quail?

[GrimApatheia]

Hi,
I have some adult button quail that are currently indoors, as well as some coturnix outdoors. I've recently purchased a 50lb bag of plain play sand for one of my aquariums and have some leftover. It's a bit dusty and fine. Will this be safe to use as bedding or in dust baths for either species? I've read multiple statements both saying it's not safe and it's fine.

Play sand has a tendency to clump and sometimes has chemicals in it. Plain construction sand or garden dirt is better, in my opinion. They will eat some of it, and it might be fine, but there is some risk.
