Then, is it safe to drink from pewter?
Note that antique pewter or, occasionally cheaper eastern pewter, may contain lead. This tends to discolor over time to a grey-blue color. Over time drinking a beverage from a tankard made of leaded pewter or lower grades of pewter can be very bad for your health, and we agree with the FDA that this is a bad idea.
Secondly, how can I tell if my pewter contains lead? The resulting mark clues you in to how much lead is in the pewter: If the mark is heavy and dark, there's lots of lead; if it's lighter, there's more tin in the mix; and if it's silvery, then it's the better quality pewter. Modern pewter mixes the tin with copper, antimony, and/or bismuth as opposed to lead.
In this manner, is it safe to put food on pewter?
Pewter is not recommended for use as a food container because even small amounts of the acids found naturally in some foods can cause pewter to pit or discolor.
When did they stop using lead in pewter?
However, lead was not banned from pewter for health reasons until the 1970s. It is more likely that pewterers gradually moved away from leaded alloys and towards antimony based pewters because they allowed for a new processing technique.
