Opinions on Excavator Clay?

[Tiny Boidae]

I've had a few bags of this Zoo Med Excavator Clay for a while now. I honestly don't even remember why or when I got it, but I want to use it as I progress towards more natural terrariums for my animals. I want to use it as a mixture for my sand boas and the baird's rat snake, but I guess I hadn't thought out the specifics until it was brought up lol.

Do I have to worry about moisture if I add it to the substrate? I don't mist down these enclosures, but at times someone will drag some moss out of the humid hide or spill some water and I know it has a tendency to harden into something like concrete. I also have some messy eaters, so I'm worried about them ingesting the excavator's clay and getting impacted. It's not even loose substrates, but just this one that I'm kinda concerned about. If anyone's used it in the past, I'd appreciate the commentary.
