I've made soap a couple times with my sister in law, but I have yet to make a batch totally on my own yet. I'm still in the process of rounding up all the necessary supplies before I really dive into this. I'm looking around trying to buy a pot, but I'm not exactly sure what I'm supposed to buy. I think it's supposed to be stainless steel, right? Other than that, what other requirements/features should I be looking for? Are there certain brands/suppliers that are better than others? What price range should i be looking in?
