"Opalescent glass is a generalized term for clear and semi-opaque pressed glass, cloudy, marbled, and sometimes accented with subtle coloring all combining for form a milky opalescence in the glass. While Rene Lalique may be recognized by most as the pinnacle of opalescent glassmaking, stained glass first evolved in the late 1800's and early 1900's during hte Art Nouveau period when American glassmakers transformed European stained glass used in cathedrals into the translucent milky glass we now refer to as opalescent. John LaFarge and Louis Comfort Tiffany were two American artists who first experimented with opalescent effects, driven by their desire to use glass in creating beautiful visual scenes in art without painting. Opalescent glass was first developed and patented by John LaFarge in 1879, but it was Tiffany who created the masterworks in glass for which he is still so well known today. Tiffany created totally new colors in glass and used glass in new forms that evoked the forms of nature.

The opalescent effect is a glassmaking technique used by many manufacturers to greater or lesser degrees of artistry, produced in the cooling process, which creates the milky opalescent effect, which illuminates any coloration when light shines on it. Sometimes the opalescent effect was created along the edge of a piece, often coupled with wavy effects and making for an elegant yet subtle look. This opalescence is also created in the glassmaking by alternating heating and cooling of the glass and with the addition of chemical additives to create the desired effect. Many U.S. manufacturers made this type of opalescent glass, most notably Fenton, Northwood, Hobbs, and American Glass."
