Could I use Clay to make rock formations?

[TheWaterBoy]

I was wondering if I could use clay to sculpt rock formations. I would plan on fireing it. ( I think thats what you call it ) I was just wondering cause it seemed like a cheap way to get my own designs for rock formations. I was thinking it would be ok cause people use clay pots. But I dunno.

if its been fiered it should be fine, as long as you dont paint it or die it

no un-natrual chemical! if your not sure, ask, or don't do it!

Sounds safe, if you want to paint it, use pond-friendly paint found at most home renovation or gardening stores. Also, do you guys know how to make a newly bought clay pot safe for a fish tank.

Do a vinegar test I think. put a few drops on it and if it doesnt bubble there fine.

I hope someone will confirm this cause I am not sure if I am right.

clay would be fine in a tank as long as its fired, you can use proper paints and dyes on it as long as it has been glaze fired aswell (second firing.. i dont know the ins and outs of it)

Thats good. Thanks for the info. I knew there was more reason for taking ceramics in high school than just a easy A.
