Vintage salt pottery (c. 1970s) mixing bowl: 6,059 ppm lead.
A mama asked me to test this because she had made a batch of Kombucha in it and the Kombucha was making her feel sick/ light headed/ dizzy.
Note: I am not saying this particular bowl will poison the people using it. I am saying that there is no reason for one of the most potent neurotoxins known to man to be in our cookware. Period.
