Is the traditional earthen casserole poisonous and lead-containing?
Traditional earthen casserole generally does not contain poison and lead.

According to the composition characteristics of lead, because it is silvery white and soft, we can scrape the casserole with our nails to see if there are any scratches. If so, this casserole contains lead.

Wipe white paper on the pot. If the white paper turns black, it also means that the casserole contains lead.
