It is made of pewter, an alloy primarily composed of tin, often hardened with small amounts of other metals like copper, lead (in older pieces), zinc, or antimony.
Design:
This specific piece features intricate relief decorations depicting figures, possibly a scene from daily life or a historical/mythological theme, which was common in German pewterware.
Historical Context:
Pewter has been used for drinking vessels since antiquity, with significant use in Europe during medieval times and beyond.
Safety:
While modern pewter is lead-free and safe for drinking, older antique pieces like this one might contain lead, which can be identified by a grayish-black patina.
