Not Ysart

Here are some examples of glass that is not made by the Ysart family and mostly not by any of the related companies.
James Powell Czechoslovakia Czechoslovakia Czechoslovakia
James Powell Cloudy glass Czechoslovakian chrysophase glass - Monart glass lookalike Czechoslovakian chrysophase glass - Monart glass lookalike Czechoslovakian chrysophase glass - Monart glass lookalike
This piece is by James Powell & Sons (aka Whitefriars) and was known as ‘Cloudy’ glass. It was two examples of this glass, wrongly identified as Monart, that got me started on the Ysart family’s glass. This first is very much like Monart at first glance; also seen with a pink or pale blue ground. It was made in Czechoslovakia somewhere between 1930-1970. A very worn label from one example is shown. Can anyone identify the maker? It has been referred to as Chrysophase glass, which means with aventurine.

NEW INFORMATION May 2006
Harrachov glassworks introduced chrysoprase c 1827 a coloured glass that is a mixture of uranium glass with bone or alabaster glass.Obviously much earlier than this threads subject! But it does show the term was used by Harrachov.
If anyone has a piece of this glass can they check if it is Uranium glass?

Bohemia/Stourbridge?

This has been referred to as ‘Cellophane’ glass. It is probably Bohemian or Stourbridge. The glass is quite thick and the pontil ground and polished. Often mis-labelled as Monart. The most common colour is the Orange and Green (middle and detail). A red and blue combination is less common and the single coloured red piece (left) is the only one I have seen. The dark banding in the photographs is an optical effect. Actual colouring is regular. These are well made and to date no attribution of maker has been found. They are probably contemporary with Monart. More below.

More examples of ‘Cellophane’ glass.
Bohemia/Stourbridge? Bohemia/USA? Schneider - France
Monart glass lookalike - unknown maker Monart glass lookalike - Unknown US or Czech? Monart glass lookalike - Unknown US or Czech? Monart glass lookalike - Schneider
Another example of “Cellophane” glass. Same orangey-brown as before but dark reds and browns at top. Another piece of Bohemian glass, but it has also been attributed to the American “Union Glass Company” Can you add to this?. Typically lined decoration in two colours, usually lighter on top half. Often with silver flakes similar to Monart. Also attributed to American Union Glass or Bohemia; features Mica. An interesting glassware that deserves more recognition. Schneider. Signed and rarely confused with Monart. Polished pontil and high lead content. The orange in this example is identical to that used in Monart. 165mm high.
Isle of Wight Glass - UK
Ysart glass lookalike - IOW glass Ysart glass lookalike - IOW glass Ysart glass lookalike - IOW glass Ysart glass lookalike - IOW glass
Isle of Wight Glass is unlikely to be confused with Monart but it could get confused with later Strathearn. The main reason for confusion is that the ‘flame’ seal can get confused with the Strathearn ‘Leaping Salmon’ seal. The IOW seal was incorrectly linked to Strathearn in Anne Geffken Pullin’s book “Glass Signatures, Trademarks and Trade Names from the Seventeenth to the Twentieth Century”, Radnor, PA. Wallace-Homestead, 1986.
Isle of Wight Glass website		 Isle of Wight Glass with seal. Non standard shape in colouring from the Aurene Range produced between 1973 and 1981.
James Couper - Scotland Nazeing Glass - UK Steuben - USA
James Couper Clutha glass designed by Christopher Dresser Nazeing Glass 1930's not Monart Steuben Cluthra not Monart Glass Steuben Cluthra not Monart Glass
Clutha was produced by James Couper and Sons of Glasgow to designs of Christoper Dresser. The finest examples are very rare and even ordinary pieces like the one shown can fetch surprising prices. Glass by Nazeing Glass. Usually a much thinner glass than used for Monart. Closer to Gray Stan in style. More to come. This appeared on eBay attributed as Monart! It is Steuben Cluthra from the Carder period. Nearly an expensive mistake for the seller as it is a much more valuable glass than Monart.

I have seen these on a few occasions and were usually attributed to Stourbridge, but no specific glasswork so, I assume that is guessing. Example is 8" 205mm high, amber body of thick glass with no ‘ring’ when tapped, dark red and brown decoration with silver flakes and some bubbles. Lots of aventurine and stylistically close to the Czech chrysophase vases in the top row but this is a heavier glass. Not seen that often in UK which implies non-British origin... waiting for a labelled example!
