Title: Czechoslavakian Chrysophase glass. AND Cellophane
Post by: Frank on December 08, 2004, 07:39:00 PM
Marcus could you have a look at the Czech vases on the first row of THIS PAGE (http://www.ysartglass.com/Ysart/NotYsart.htm) please. I would love to ID the glassworks and have been trying for only 20 years so far, ditto the second row which might not be Czech/Bohemian etc.

Hi Frank, With my less than perfect knowledge, the most obvious candidate amongst Czech/Slovak/Bohemian glassworks for this glass may well be Ceskomoravske Sklarny, at Krasno nad Becvou, not to be confused with Krosno, Poland. They appear to have had some similar glass, though not necessarily the forms. Examples that spring to mind are those one-offs, designed by L. Smrckova, @ 1940, Bohemian Glass, Drahatova and Langhamer for Crystalex, Novy Bor, 1985?, and Modernes Glas Von Ludvika Smrckova, M Holubova, Artia, Prague, 1961.
I do not currently have examples of their labels. Ivo?

The one labelled exampled, shown, included the word Chrysoprase and part of Czechoslovakia, the rest was illegible. The label was either embossed on silver coated paper or printed with a thermographic silver ink. That places it betweem the thirties to late sixties. I cannot see it being later. It also occurs in a pastel blue ground and a pastel pink ground. I feel it is 50's. It is certainly not a one off design as it occurs in so many shapes and is often styled with the fifties version of Art Deco as well as more traditional shapes.

Ivo has thought about it in the past, I never let anyone who shows some interest in this area get away without their thoughts. :twisted:

We will get there in the end. Thanks.

Sorry Frank, was pointing in the direction of the type of glass as used for a series of one offs, not that the forms themselves were one-offs.

Hi Frank,
Having gone back and looked at several images this morning, the glassworks above may be a good candidate as possible producers of cellophane glass as seen in line 2, the green/brown colourway.

I googled Ceskomoravske Sklarny but did not get very far as everything was in Czech, one was an auction listing but no image.

The 'Cellophane' glass is quite unusual being a very thick glass, typically 3x-4x the thickness of Monart. Quality is high and I wonder at how such heavy pieces were made. Pontils are ground and polished. Colour most commonly found is the Green/Orangey-Brown as shown, Blue/Red appears less frequently and other colourings from time to time.  The colour has an unusual quality, fully translucent, that I have not seen elsewhere. It is the similarity of the colouring to old cellophane sweet wrappers that lead to my term for the glass. Very difficult to get across in a photograph. There appears to be many designs and I have several more still to include on the site. Generally they exhibit sufficient wear that suggests a date as early as the 1920's being possible and most surface in the UK, usually described as Monart. Some years ago a collector reported seeing an example at the Passau Glass museum but did not take any notes. When I went there could find nothing even close and at the time of my visit there was no one available to give advice.

I have added some images and improved all of the other images on the page now. LINK (http://www.ysartglass.com/NotYsart.htm)

One of the major difficulties with Czechoslovakian glassworks is the difficulty in establishing the post-war histories of glassworks during the years of communist control. The expulsion of Sudeten Germans, with the changing of placenames, Carlsbad to Karlovy Vary etc did not help.
Following the nationalisation of the major industries in 1945, things got even more uncertain. For example Borocrystal based in Novy Bor, consisted of 55 glass workshops (1948) but according to some sources, by 1951, the Borocrystal Narodni Podnik had closed 30 workshops, with another nine devolved???? (Closed/Making different product???Transferred to other national corporations???) Nor is it easy to find out which workshops were involved, which closed, etc.

Centralised planning and organisation linked companies together, and few factories kept original names. Moser and Egermann just hung on to their names,  as pragmatists realised the importance of quality brand-names.In 1951, the first re-organisation of the glass industry, towards the end of the First Five-Year Plan, created eight Narodni Podniks, covering 43 factories. Changes, re-structuring, renaming happened on a regular basis.

I am working my way through this morass, to work out a chronology of post-war Czechoslovakian glassworks, but it is slow going. Once I have more on Cesko-moravske, will post it for you.

Frank, Ivo,
What info do you have on a company called S. Reich and Co? It would appear that Reich had some 14 factories around the Krasno nad Becvou area, pre-war and that at least some of these became part of Ceskomoravske Sklarny.

Ivo is away. In his book he mentions:

S Reich & Co. Glasfabriek, Krasno CZ 1855-1939 - Lighting and shades.

Hi guys I'm back from a most interesting romp around Vienna, Bratislava and Budapest.
The complete catalogues of S. Reich were published 2003 by Geiselberger (PK2003-2-2); they are reprints from the originals which are in Okresniho vlastivedn√©ho muzea Vsetin and Valasske Mezirici.  The first available one is from the 1860s, then there are catalogues from 1873, 1880, 1925, 1930, 1934, 1935, 1936.  With a bit of luck you can get them from Geiselberger in PDF format. How's your German, Marcus?

"How's your German, Marcus?"
Ivo,
Worse than my Czech or French, so will access the Czech versions.
Thanks for the pointer, seems an extremely interesting site.
Regards,
Marcus

For research purposes you should contact him, his database of CZ glassworks and publications is fabulous. As luck will have it most of the glass brochures are in German - the trade language of the time - not in czech.

New information.

Harrachov glassworks introduced chrysoprase c 1827 a coloured glass that is a mixture of uranium glass with bone or alabaster glass.

Spelling of chrysoprase corrected here and in other threads.

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?

I don't know whether this adds anything to this discussion or just confuses things, but according to Langhamer's The Legend of Bohemian Glass, "the 1830s brought the first glass colored with uranium oxide" and Harrach "made uranium glass containing some alabaster under the name 'chrysopras' (1831), and later perfected a uranium yellow glass."
Title: Re: Czechoslavakian Chrysophase glass. AND Cellophane
Post by: Ivo on July 04, 2008, 06:47:36 AM
Correction, please. The first uranium glass dates from 1830 (not circa) and was made by Franz-Anton Riedel.

"Chrysopras(e)" is an opaque apple-green banded chalcedony.

What Langhamer refers to is in the range of imitation semi-precious stones which was pioneered by Harrach'sche, Egermann and Bucquoy -  but Chrysoprase was not perfected as a solid colour until 1843 when it was launched by Baccarat.

Uranium oxide as a colorant was used for imitation precious stones before it was developed for colouring glass.

Thanks Ivo, I am fairly certain that the Chrysophase I seek was a product name used 1920s-50's or 60's latest and probably not uranium, just marvered and cased glass with aventurine found in apple green, pastel blue and pastel pink.

Somewhere there must be one with a complete label. But at least we have gotten a lot further in the last 4 years than in the last 20 of hunting.

Cellophane vase for sale here with an acid etched mark on the base.
In case the sale disappears, the vase is orange splotches with a black?(v.dark brown?) splotched (smaller splotches than the orange effect on the body) effect around the rim.
The shape curves down from the rim into a small bottom that has an applied clear glass foot.
The base has a fairly large pontil mark (but not wide like a French pontil mark or a Stevens and Williams pontil mark) with an acid etched mark on it. 
The acid etched mark is a circle with what appears to be two letters inside it (bad photo or bad mark and difficult to photograph).  The letters appear to be IU or nI - very difficult to tell.
Described by seller as:
'This is very heavy and solid measuring about 7 1/4" tall and 5 5/8" diameter. Very thick glass that has layers of deep orange/red and black, over a clear end of day orange spotted layer.  ...'

Nicely spotted, have asked seller for clearer picture with advice on doing that.

I'm not sure where this fits in really but this evening I just suddenly wondered whether the 'cellophane' vases we see were made by Reich Krasno
http://www.pressglas-korrespondenz.de/aktuelles/pdf/pk-2014-1w-menay-reich-vase-1934.pdf

see page 5 on the link (seite 5/7) and 2nd photo down on the right hand side of the page

So adding that here just in case I forget :)
