Jadeite, “Jadite” or “Jade-ite” is a type of jade green opaque milk glass, originally popular in the United States in the early to mid-20th century. A blue milk glass called “Delphite” (Delfite, Jeannette Glass) and "Azur-ite" (Anchor Hocking) was also produced for several years.
McKee Glass introduced their jade green (trade name “Skokie” green) colored kitchen and table wear in 1930.[citation needed] Shortly after in 1932, Jeannette Glass began their production of this color glass, in doing so coining the term Jadite.[citation needed] In the mid-1940's, Jade-ite was produced by Anchor Hocking.[citation needed] Early versions produced by McKee Glass Company and Jeannette Glass Company (both of Jeannette, PA) are a type of uranium glass that will glow under UV light.[citation needed]
While McKee Glass was the first to produce tableware in this jadeite color glass, the history of this color dates back into the 19th century.[citation needed] Other U.S. and European glassmakers produced items in this color. Examples can be seen from various makers such as Tarentum Glass, Challinor Taylor, and Portieux Vallerysthal of France.[citation needed]
Jadeite glass experienced a resurgence of popularity in the late 20th century, initially in the 1970s through the “heritage” revival of U.S. glassmakers like Fenton and Westmoreland Glass.[citation needed] Westmoreland produced new glassware made in historical and current molds to cater to the color trends at the time.
But the true increase in popularity was largely due to the influence of Martha Stewart,[citation needed] who began showcasing her collection of vintage glass on her television show. Interest continued to intensify during the release of her own line of jadeite - sold initially through the Martha by Mail catalogs in the late 1990s.[citation needed] Domestic glassmakers L.E. Smith, Fenton, and more recently Mosser Glass have contributed to the Martha Stewart lines with heritage molded pieces in jadeite glass.[citation needed] The molds for these pieces were both original and reproduction patterns of glassware made by their own companies, as well as molds previously owned by companies such as Portieaux Vallerysthal of France.[citation needed] This glassware was made in the same old-world method that these companies had been producing with throughout the 20th century.[citation needed]
The release of the Martha by Mail jadeite line in the late 1990s renewed interest in this glass color, and spurred a surge in collecting of this color of glass.[citation needed] Today, companies both domestically and internationally produce jadeite glass. You can find imported jadeite items from brands such as Pioneer Woman, Gibson, Grace Mitchell, Tablecraft, and others. Mosser Glass currently produces hand-made jadeite glass pieces in their factory in Cambridge, Ohio.[citation needed]
Today collectors are able to procure a variety of original, original reproduction, and new/fantasy jadeite glass pieces.
