Sculpey Clay for Aquarium Decor

[Aynia]

Hey all! I'm back with another question.

So I'm a pretty artsy type and I have a few pounds of sculpey clay that I haven't used yet. I was just wondering your thoughts on whether this is safe for aquariums, or would it be safe if I painted it with aquarium sealant after baking and cooling to be safe? I'd love to be able to make some custom decorations for our tank, but I don't want to run the possibility of killing our fish. I've read conflicting opinions, ranging from a hard no, to an it's fine because they've change their polymerization chemicals in the past few years, to people who actively have it in their tanks with no issues. But better safe than sorry. What are you guys' thoughts?

I would say it is quite safe. I have used it in tanks in the past. Made a rather good size cave for a crayfish and he had no issues with it. But to be on the safe side after i baked it i let it soak in water for a week. that way if something is gonna leech it should clear it up.
