Consider the wear, tear, and tarnish. If it’s an authentic piece at a good price, embrace its worn patina―true evidence that no two pieces are alike. Some reproductions are also made to appear worn, so don’t assume all tarnished pieces are authentic antiques.
Weigh your options. Mercury glass reproductions can weigh up to four times more than the real thing. Although this method isn’t foolproof―some reproductions feel hollow throughout―it will often help you differentiate between the two.
Buy in the off-season. Genia displays her mercury glass year-round and loves mixing it with other holiday decorations, especially at Easter. Also known as “poor man’s silver,” mercury glass takes on many roles and maintains elegance throughout the year.
