Milk glass is a relatively recent name for opaque, milky white or colored glass, that is blown or pressed into a wide variety of shapes. Animal-shaped covered dishes are popular collectibles. First made in Venice in the 16th century, the white color is achieved through the addition of tin oxide. 19th-century glassmakers called milky white opaque glass "Opal". Other milk glass colors include blue, pink, yellow, brown, and black.
Made into decorative dinner-ware, lamps, vases, and costume jewelry, milk glass was highly popular during the fin de siecle. Pieces made for the wealthy of the Gilded Age are known for their delicacy and beauty in color and design, while Depression glass pieces of the 1930s and '40s are less so.
Milk glass has a considerable following of collectors, and many examples can be found on eBay. Some glass makers continue to produce it, including reproductions of popular collectible pieces and patterns.
