To those of you whom include them in your practices:
Is there one hard set "rule" about what they should be made of? I have been looking it seems like forever (just a few years, not exactly forever but I'm impatient sometimes) for one and the other day while digging aroud in a flea markety type place I found a small "cauldron" looking pot, standing on three feet and at $1 it seemed like a find. Except it's made of brass. I'm not sure I'd be doing a lot of work with one but I do want one to sit on my altar, once I get it together and this one seemed to want to come home with me so...any rule saying brass is a no no?
Just curious in general and happy to have all opinions.

Thankies much in advance!

Daphne,
Way back when I was looking into Wicca, I found one on eBay. It's cast iron and I found it under "bean pot" search. I suspect that I would have been happy with any fireproof material, but cast iron is what I found.
