Understanding the Usage of Pewter in Drinking Vessels
What beverages should not be consumed from pewter vessels?
A. Alcoholic drinks and carbonated beverages
B. Water and fruit juices
C. Milk and tea
Answer:
Alcohol and other fizzy beverages should never be consumed from pewter. It should be noted that both expensive eastern pewter and ancient pewter may contain lead.
Pewter is a metal alloy composed primarily of tin, with the remainder typically consisting of copper, antimony, bismuth, and (occasionally) silver. Lead was used in the past, but it is no longer considered safe.
Over time, this turns a grey-blue colour. Over time, consuming liquids from a tankard made of leaded pewter or lesser pewter grades might be detrimental to your health.
