Hi i look afte many tanks, myself i have a ten half moon but am upgrading to a 47 colum (hopefully soon). My question is as follows, i am able to make clay and kiln fire it, i was wondering if i can leave it un finished or whether it has to be glazed. It should be alright but what i am wondering is will it throw off any of the chemicals? It technically wont be unfinished but the finished result is much like hardened fired clay. I want to make a back ground as well as some very tall ornaments with a smaller footprint. as well as some caves that can be seen from the side of the glass. I know fired is alright but i am unsure as to raw fired clay.
also if there is any other way to make bacgrounds with a smooth finish i am open to ideas.

The Ph could dissolve Chemicals and Elements out of your fired decor. I would research the Chemicals used in firing your pottery, then list them here. On the Raw stuff, you could test it like a rock and use some vinegar (I believe) or some PH down to see if it fizzes (any dissolves).

Fired clay will certainly dissolve slowly and that may or may not be an issue for the fish. Why not glaze the pieces?

There are several products that people use as substrates, that I believe are baked clay. Turface, Soil Master Select, plain kitty litter, Oil-Dri, aquariumplants.com substrate, etc.

To add to that list: Flourite, Eco-complete

I believe ceramics need to be glazed to seal them.

ok, i will glaze them. i have had fired peices in the tank before with out a problem. What i mean with the unfinished clay is a sort of red then you use a second clay when that's fired to give it a burnt /blackened look and fire it again.
