With plain aluminum the only a problem to use with hydrochloric acid or sodium hydroxide, etc. A lot of people just dislike aluminum cookware, I being one of them, so it gets written off even for use in everything that doesn't involve those two chemicals specifically.
Now porcelain is a different story, and can be eroded by a variety of weak and strong acids. However if you are using lemons or something in your Jurema brew, that is alright. Over time the coating with degrade if you continuously cook acidic things in the pot, but I figure it wouldn't be noticeable for a long time. Dunno, there is such a thing as being too particular about one's materials. You are going to yak it all up anyway so hey take a chance, :twisted:
