J - O


           Josephinenhütte - Silesia - c. 1842 - Present (currently called Huta Szkla Julia)

          Early stamped mark on overlay vase

Kelsey Pilgrim Cameo - Ceredo, West Virginia - c. 1980's - 2001

Under the direction of Kelsey Murphy, Pilgrim Glass introduced a line of cameo glass in the 1980's. Cased glass is carved through a sandblasting process, to reveal the desired color and design. The designs are Murphy’s own pictorial scenes. All pieces are signed by Kelsey. Most are issued in limited editions and numbered.

Kimball Glass Co. - Vineland, N.J. - c. 1931-1932

After Victor Durand died in 1931, his partner Col. Evan Kimball took over the business and began exclusively producing cluthra type glass similar to what Frederick Carder had produced at Steuben. This venture only lasted a year and then the business shut down. Because of the short production period, Kimball glass is very hard to come by. Kimball used the same shapes as Durand used.

Kralik - Bohemia - c.1877 - 1944

Original paper label from 1920's art deco covered bowl.

This signature is contemporary.  I've seen enough of these contemporary art nouveau inspired pieces to believe their legit, but have been unable to find any data on them.  It may or may not be the same Kralik that closed prior to WWII.  If you have current data on this, please contact me.


Rene Lalique - France - 1909 - Present

René Jules Lalique. Initially designed jewelry and then went on to design pressed, mould-blown & engraved glass.  Lalique continued to operate within the family by Marc Lalique (René's son), and Marie-Claude Lalique (Marc's daughter).  They’re still in operation today.

Legras - France - c. 1864 - 1930's

Auguste Legras was a glass worker who bought the factory at Saint-Denis, near Paris, in 1864. He knew a great success with his famous enameled colored and  acid engraved glass. In 1897, he bought two others big factories.  His son, Charles Legras, succeed in 1909 and the production was stopped during the WWI.  He reopened in 1919 until 1931 and produced many original new Art Deco works.

Legras Mont Joye

Legras Art Deco Cameo Glass c. 1931

Libbey Glass Co - Toledo, OH - 1880's - Present

Acid etched mark on Libbey Amberina  

Used on Mt Washington shakers, Smith Bros 1893 Worlds Fair pieces, and other Mt Washington items that were apparently contracted to Libbey when Mt Washington was unable to keep up with production requirements.

Loetz (original name: Glasfabrik Johann Loetz Witwe) -  Klostermühle, Bohemia - c. 1852 - 1947


Authentic Loetz Austria signatures were engraved in such a way that the engraving is easy to discern after seeing an authentic engraving in which the engraving tool oscillated vertically (rapidly moved up and down while engraving).

Marie Kirschner (Berlin) designed 277 unique patterns for her own personal sales, of which the Loetz factory produced signing them with her MK monogram as seen above.  Marie funded these designs, by in return designing glass for the Loetz factory's normal production, and some of the glass pieces from her own series were also adopted by the factory for its normal production range.  These pieces do not carry the artist's signature as the Loetz factory didn't have the rights to use her MK monogram.

Originally known for his wonderful furniture designs, he also designed for Daum, typically Art Deco metal mounts for glass.

M A R I E ???  Mark unknown, please email if you have info on this one.


Moda (sometimes signed Moda Nancy) - Nancy, France - c. 1918 - 1925

Daum Brothers & Co, Glassmakings of Nancy.  Seems to be an enameled line, made to appear to be similiar to Daum Nancy's earlier enameled cameo work, but these are typically not cameo work.  They can have an acid etched finish, which is then enameled over.

Monart Glass - Perth, Scotland - c. 1924 - 1961

Moser - Karlsbad, Bohemia - c. 1857 - Present


Moser - Alexandrit


Moser or not? - Pieces in this decor have traditionally be attributed to Moser in various books and other references, however, after seeing this pair of vases with this PK mark, maybe it's time to reconsider this.  Most of the glassware bearing this mark are typically poor quality fireglow Victorian era glass, with low quality enameling (usually worn) certainly not done by Moser.

Moser Hussmann c.1927 - Mark from an Art Deco Cameo and engraved box

Moser Etched - Commonly found on Moser Intaglio work

Moser Wiener Werkstatte

Mt Washington Glass Company - Bedford, MA - c. 1869 - 1900

Orient and Flume - Chico, CA - c. 1972 - Present

Founded by Douglas and Carol Boyd, and David Hopper the glass studio directed their efforts towards recreating the silver-luster of iridescent glass of such turn-of-the-century studios as Tiffany, Steuben, and Loetz. They continually experimented with glass formulas, glass melting, and innovative decorating techniques.  In time, this led to the creation of their intricate, three-dimensional design's encased in clear glass.
