Making my own tank decorations?

[Winterose]

I actually just had the idea, could i possibly use sculpy clay to make decorations for my tank? if i could how would i go about doing so? would it basically be sculpt -> Paint -> seal -> add to tank? or am i missing a step or would the clay be toxic to the fish? and what paint would i use to paint it so it wouldn't kill the fish?

I don't know much about clay, but my ex mother in law own a pottery making business so i have seen it done. I think one step you are missing is the kiln. i believe it is what makes the clay solid. Could probably do some research pn it to verify what I am telling you, but i'm thinking if the decor you are making will fit in the oven, the oven will work.

Sculpy you would bake in an oven and ya most of the parts i'm making are small as they are only for a 20g tank

I think the clay you're referring to would dissolve over time unless it were completely sealed/painted with Krylon Fusion.

i don't think it would dissolve, i would seal it a bunch of times thought just to make sure it didn't cause thats the last thing I'd want to have happen. but if i seal it extra good it should be fine right?

*sigh* no... it will probably dissolve unless it is regular firing clay... to use this... you have to have a kiln or you can lock it in your BBQ at +1k temperatures

Foam works just as well and can be made to look like a variety of materials for a lower cost/volume as well. The "saltwater vivarium" build thread uses this method. DIYLR can also work, though you may be happier controlling the texture through carving vs. casting.

I would suggest runnig a small test batch of watever medium(s) you chose to use, and then comparing them for appearances and durability.

Good luck
