Yeah and they knew that was bad too. Probably if they had a good way of testing for lead acetate, they&#x27;d probably have thrown the occasional wine merchant to the lions.<p>I have a copy of De re Metallica[1] it has a whole chapter on stuff like this and that&#x27;s 1500&#x27;s Europe. Lead is kinda tricky since it tends to get passivized most of the time by sulfate and phosphate. Except when it doesn&#x27;t and then it&#x27;s insidiously bad.<p>[1] Translated Herbert Hoover (yes that one).
