 Pairpoint Manufacturing Co. - New Bedford, MA - c. 1880 - Present

The Pairpoint Manufacturing Company was established in 1880 in New Bedford, Massachusetts. The factory began as a metalwork's.   Near the Pairpoint factory was the Mt. Washington Glassworks which made fine glassware, the two companies merged in 1894 and became known as the Pairpoint Corporation. From the late 1890s until the 1930s, lamps and lamp accessories were an important part of Pairpoint's production.

Perthuis - Paris - c. 1900

This is a real mystery mark, a gold gilded medieval dragon touting a banner with the words 'Perthuis Paris' on it.  See the Daum Nancy perfume flacon below.  I have the identical perfume flacon bearing this Perthuis Paris mark.  Identical pieces with two different marks leads me to believe these may have been done for a Paris Salon.   If anyone has any info on the Perthuis Paris mark, please drop me a note at bsevern@Glasscollector.net.

Here's the perfume flacon bearing the Daum Nancy mark.  It's definitely a traditional Daum Nancy perfume flacon design.



Peynaud - Bordeaux, France - c. 1910 - 1945

Glassworks produced enameled glass works, often resembling Legras cameo glass.



Phoenix Glass - Phillipsburg, PA - c. 1880 - 1970

The Phoenix Glass Company was founded in 1880 in Phillipsburg, PA.  Initially they made leaded glass chimneys and shades for lamps, and formed alliances with a number of glassworks and individuals who could bring glass-making skills to Phoenix. During the 1880's and 1890's, under the direction of Joseph Webb, they produced a large quantity of cut glass, etched glass, hand decorated glass, and Victorian colored art glass, such as mother-of-pearl satin glass which they patented in 1885.

This continued until 1894, when Phoenix decided to focus exclusively on lighting products. (Webb left the company at the same time, and went on to work for several other glass making companies until his death in 1905.)

Amazingly the Phoenix Glass Company continued in business until 1970, making glassware for the lighting industry.  It was taken over by Anchor Hocking, who made for special occasions very limited productions of some of the old Phoenix sculpted glass. 

For more information on Phoenix Art Glass, I highly recommend Leland Marple's book "Phoenix Art Glass" published by Schiffer Publishing.

This 'Patent' mark tends to be found on their highest quality MOP glass, done when Webb was designing their colored glass.

Pittsburgh Lamp Brass and Glass Co - Pittsburgh, PA - c. 1901 - 1926

Pittsburgh Lamp, Brass and Glass Company was founded by renowned chemist, Nicolas Kopp in 1901.  He used his knowledge to make beautiful lamps and tableware in many colors, as well as fine etched crystal.  Kopp had developed Selenium Red earlier that met the railroad’s signaling light standards, and it was very profitable as the railroad industry flourished. 

 In 1903 the Pittsburgh Lamp, Brass and Glass Company (commonly called “Pilabrasgo”) absorbed Dithridge & Company.  

The prosperity didn't last forever, and in 1926 Pilabrasgo went bankrupt.

Poschinger - Frauenau, Germany - c. 1568 - Present

RK Dresden Germany - I have no info on this glass mark, if anyone does, please let me know.

It's highly possible this mark was also used for porcelain.

Roccoco Art Glass - Bohemia - c. 1880-1900's
The so called "faux cameo" or "pseudo-cameo" was made by the Bohemians to capitalize on the highly successful English cameo glass of the time. They are typically marked "Florentine Art Cameo," "Cameo Art," "ROCCO ART GLASS" etc.  These ware's from a distance resemble English cameo but upon close examination are not very high quality. The cameo part is actually white raised enamel, and many of the blanks were done in similar colors and shapes as Webb and Stevens & Williams. The inexpensive Bohemian copies were so successful, that the market for authentic English cameo glass plummeted, and it was discontinued due to it no longer being profitable.


Rosenthal - Amberg, Germany - c. 1954 - Present

Although founded in 1879 by Philipp Rosenthal as a porcelain decorator and manufacturer, it's not until 1954 they change direction and start producing high end glass products. 


Sabino - Paris, France - 1919 - Present

Marius Ernest Sabino. Best known for their opalescent glass, but they also produced limited quantities of clear, colored, frosted, stained, and enameled glass.  The entire operation (including molds) was sold to a firm in Texas in 1978, although the manufacturing today continues in France.

Smith Brothers - New Bedford, MA. - c. 1855 - 1900

Smith Brothers, founded by Harry and Alfred Smith was originally a decorating shop decorating high quality glass blanks from many local glass makers, including Sandwich Glass and Mt Washington Glass Works.  For a brief period they worked for Mt Washington, but left in 1871 to pursue their own business.  They decorated local and imported opal glass blanks with decorative motifs including flowers, birds, landscapes, and orientalia.

Steuben / Frederick Carder era - Corning, NY - c. 1903 - 1932


Aurene was registered in 1904, and ceased production in 1932.  As amazing as Carders glass is, the Aurene  signatures are not, as they were apparently signed with a rather crude engraving tool.  Not all Aurene glass is marked, and marked pieces can be marked in a variety of ways, such as 'Aurene', 'Steuben Aurene', 'Steuben Aurene with a catalog #' or any combination.

Steuben acid banner mark was both acid etched and also applied to shade fitters with a silver material that was easily wiped off.

Stevens & Williams - Brierley Hill / Stourbridge, England - c. 1847 - 1933

Started by Joseph Silvers, whose daughters married William Stevens & Samuel Cox Williams, at which time the name was changed to Stevens & Williams.  Stevens & Williams was an innovative and ingenious glass factory that drew some of the most talented glass designers such as - Frederick Carder (1880-1903), John Northwood (1882), John Northwood II, William Northwood, Joshua Hodgetts, etc.  Many of the designers from Stevens & Williams went on to found their own prominent glass works elsewhere.

Tiffany, Louis Comfort - Long Island, NY - c. 1881 - 1928 (Favrile blown glass)

Initially Tiffany sourced glass produced by outside firms, but this did not give him control and subsequently lacked the quality that Tiffany demanded.  As his fascination with glass grew, he experimented with lustering techniques, largely inspired by the natural iridescence of ancient Roman glass that he saw in his previous travels to Europe. He patented his first glass-lustering technique in 1881.  Favrile glass, the trademark for Tiffany handmade glass, resulted from these experiments,  and  with the exception his lamps, it's his blown glass that he's best known for.

Tiffany set up his own glassworks at Corona, Long Island and put a brilliant Englishman, Arthur J. Nash, in charge. His previous companies had all been concerned with interior decoration; this one, Tiffany Furnaces, concentrated on decorative blown glassware.  Tiffany Glass was highly successful initially, but Tiffany refused to change with the times, and as Art Nouveau glass grew out of favor, he funded the continuing operations of his glass works with his own funds.  In 1928 Arthur Nash purchased and continued to operate the glass works producing Tiffany style glass until 1931.

Villeroy & Boch - Wadgassen, Germany - c. 1842 - Present

WMF (Württembergische Metallwarenfabrik) - Geisslingen, Germany - c. 1883 - 1984

Although WMF produced glass for more then 100 years, their height of glass production was between 1926 to 1936.  A young glass designer, Karl Wiedmann, perfected the technique of iridescent glass  resulting with "Myra" crystal, which started production in 1926.  Also in 1926 they started making their famous "Ikora" glass.  Both types of art glass were produced until 1936, when they ceased producing art glass.

Walsh (John Walsh Walsh) - Birmingham, England - c. 1850 - 1951

Mainly noted for their production of cut and engraved clear crystal.  They also were highly innovative during the Victorian era producing many fine Victorian colored glass designs, such as Mother-of-pearl air trap glass (called Sateen Glass by JWW), opalescent patterned glass, colored cased and plated glass.

Webb - Thomas Webb and Sons - Stourbridge, England - c. 1840 - 1990

The founder of Thomas Webb & Sons entered the glass industry in 1829 and became a partner in the Wordsley glassworks of Webb and Richardsons. In 1833, his father, John Webb, also entered the glass industry in partnership with John Shepherd at the neighboring White House glassworks, but in 1835 John Webb died and Thomas succeeded to his fathers share in the Shepherd and Webb business. In 1840 Thomas Webb moved to the Platts, Amblecote, very near to the Dennis estate and started “Thomas Webb’s glassworks”.

In 1855 he moved to the present site, Dennis Hall.  Dennis Glassworks became a hub of the industry in which at least four of his sons eventually became involved. Thomas Webb died in 1869 at the age of 65 and was succeeded by his son, Thomas Wilkes Webb, under whose leadership the company’s fortunes prospered to such an extent that the name of Thomas Webb became known amongst connoisseurs of glassware throughout the world.

In 1878 and again in 1889, the exquisite products of Thomas Webb & Sons were displayed at the great Paris international. In both Exhibitions the Grand Prix was awarded to Dennis Glassworks.  Thomas Wilkes Webb must have been a proud man indeed to read in the 1878 exhibition’s illustrated catalogue that “Messrs. Thomas Webb & Co. of Stourbridge are the best makers of glass in the world”.  In recognition of his contribution to these exhibitions, Thomas Webb was made a Chevalier of the Legion of Honor, an award which the French seldom give to a foreigner. He died in 1891 at the early age of 54.

Dennis Hall closed it's doors in 1990.
