Milk glass

First made in Venice in the 16th century, colors include blue, pink, yellow, brown, black, and white.

The size, distribution, and density of the particles controls the overall effect; which may range from mild opalization to opaque white.

[2] [3] Made into decorative dinnerware, lamps, vases, and costume jewellery, milk glass was highly popular during the fin de siècle.

[4] A famous use of milk glass is for the four faces of the information booth clock at Grand Central Terminal in New York City.

Barbetta, the New York Italian restaurant founded in 1906 and still in business as of 2022,[5] has what is said to be the last opal glass sign in the city.
