It couldn’t unify Italy during the 16th century, but the genesis of milk glass in Venice around the same time would ultimately unite glass collectors throughout centuries. Milk glass, originally called opal glass, is a milky colored, or opaque glass, that was blown or pressed into decorative moulds to form cups, dishes and figurines—an ideal collectible as it is as useful as it is beautiful.

Historically, milk glass came in myriad colors: brown, pink, blue and even black. Despite the hue, the signature thick milky color remained intact. Milk glass exists in these colors today; yet the opaque white of milk glass wins most popularity contests among collectors.

Early milk glass was created with fluoride, an element that added fluorescence in certain light. However, fluoride quickly corroded the moulds used to manufacture the items, making the molds costly. Presently, plain glass and paint are used to mimic the appearance of milk glass. A few of the many manufacturers of milk glass include Fenton, Westmoreland, Anchor Hocking, Imperial, and Fostoria. Many of these manufacturers will have markings or specific patterns on their milk glass; counterfeit milk glass generally has neither.

Knowing the distinct styles of these and other manufacturers is paramount to keeping authenticity to your milk glass collection. The most valuable items you will find on the milk-glass market are those that were made in the 1800s. Pieces from the 1700s are even more valuable but they might be out of the price range for the casual collector.

Milk glass often came in bowls, glasses, vases, toothpick holders and pedestals. Less commonly they can be found as lamps, dinner sets and even costume jewelry. Objects outside of this group may signal a phony, so investigate further for authentication.milk glass

The 1840s through ’70s saw the combination of fluoride with flint glass to produce a mild white milk glass that when flicked rang like a bell—an easy and fun way to date a piece.

In the 1960s, the growing presence of fluoride runoff in the United States’ streams and rivers meant that the old process of manufacturing the glass had to be halted in favor of more environmentally friendly processes. This led to a decline in production as manufacturing process were reinvented.

Hobnail, named for its likeness to the thick-headed nails that once secured and protected boots, is a style in milk glass that is highly recognizable and very beautiful.
