Brass is an alloy of copper and zinc (according to Encarta Encyclopedia).
Pewter was often made with lead - but tableware, at least today, has tin
instead of lead.
It turns out that crystal is the worst common source of lead in food
products. If you keep wine in a lead crystal decanter, throw it out!
Copper is also poisonous. My family were coppersmiths, and I have a copper
tea set that my gr grandfather made. The teapot was lined with another
metal (tin as I remember, but I could be wrong-but a white metal). It is
not usable today unless I had it relined.
