Aventurine Clutha Glass Vase


130E  Allaire Collection

Date: 1890           Height: 10 cm

Description: This mainly greenish concaved Clutha glass vase with embedded air bubbles, streaks of brown, white and speckles of aventurine. Its type was patented in the 1890s by James Couper and Sons, Glasgow.  It may have been designed by Christopher Dresser or George Walton.




Remarks & History:


Christopher Dresser in the 1880’s created a new “art glass” series for the manufacturer James Couper & Sons, located in Glasgow. Sold under the trade name “Clutha,” the ancient name of Glasgow’s river Clyde., Clutha was Dresser’s only experiment in glass design. Dresser worked in many design fields, including metalwork, furniture, ceramics, and textiles. He was one of the most important designers associated with the Arts and Crafts movement in Great Britain. His interpretation of glass was radical in his time. Longnecked, bulbous vases in bubbly yellows, browns, and greens heralded the organic shapes that would become characteristic of the Art Nouveau style, but his designs also exhibited a pioneering modernism. These designs are identified by the initials “C.D.” which are incorporated with the manufacturers’ mark for their Clutha glass. (See illustration.) Most of Dresser’s designs were registered at the Patent Office in London. Another designer, George Walton of Glasgow, also produced several of the designs for Clutha glassware, and his initials will probably be found on pieces of this ware in connection with the maker’s mark and the name “Clutha” etched lightly in the base of the article.

About 1925, the Steuben Glass Works, under the direction of their master craftsman, Fred Carder, produced a very similar ware which Mr. Carder named Cluthra (clutha with an r).  Kimball and Durand Art Glass Company NJ also made Clutha glass usually in a bubbly yellow, orange, and pink color. Some of their pieces are marked with the letter “K” and, occasionally, a number or series of numbers which designated a particular design.


To produce Clutha glassware, a worker took up a light gather of pale ruby or pale-yellow or other colored glass and rolled it over a marver lightly sprinkled with bits of colored glass, mica or aventurine. The gather was reheated at the glory-hole and blown and tooled into the finished product. Couper & Sons’ Clutha glassware is full of character and quaintness, with little specks of color, and bubbles, and a general contour which tends to render the shape visible.


Aventurine is a form of quartz, characterized by its translucency and the presence of platy mineral inclusions that give a shimmering or glistening effect termed aventurescence. The most common color of aventurine is green, but it may also be orange, brown, yellow, blue, or grey.
