Westmoreland Speciality Partnership, Imperial Glass and Fenton Glass where some of the largest producers in the U.S. It is unusual to be able to pride an imprint of the manufacturer on any glass.


Production


Milk glass components hold changed over the years, but the process of making the glass remains relatively the same. Milk glass is made up of half silica, or sand, which is mixed with other chemicals and minerals to give it the milky color. The mixture is heated to a high temperature and melted to a liquid. This liquid is poured into metal molds and sealed until cool. When the molds are opened the glass pieces are shined and buffed, and some are hand painted.


Changes


Most of it is reproductions of past production. Plain glass is used along with white paint to receive an effect like milk glass. The patterns of the molds are not nearly as intricate as they were in the past. From 1840 through the 1870s flint glass was used to make milk glass. Flint contained lead and if a piece was lightly hit it would ring as if it were a bell. Fluorite was used to make the milk glass iridescent. Unfortunately, fluorite started to leach into the water system around the manufacturing plants and caused problems. Fluorite also caused molds to corrode very quickly and they could only be used a few times before they were useless.


Modern Milk Glass


Not many manufacturers make good quality milk glass today.Arsenic was used in the early days to make milk glass opalescent. Some of these pieces have a reddish glaze around the edges, and these are most prized by collectors. The use of arsenic was stopped when it was determined to be dangerous. Fluorite was used up until the 1960s. Pieces made up to this time are the most valuable.
