Is it safe to use old ceramic crocks for food uses? My husband has been collecting them and I'm really hoping to make some sauerkraut and do some other fermented veggies this year, and am wondering about safety particularly in regards to lead leaching out of them. Of course, I'd only use the ones where there are no cracks/chips in the glazes.
What do you think? Are those old crocks just for looking at, or would you trust them to use?
If not, where can I get food safe crocks?
