Title: Art-Deco style footed bowl with "glue-chip" surface
Post by: rocco on May 25, 2015, 02:25:29 PM

Bought this one out of curiosity: pressed glass (I think), the base is ground and highly polished. Diameter is 18.5 cm, height 9 cm.

The slightly iridescent champagne colour is definately applied to the outside -- the glass is colourless when looking through the base, and quite obvious at areas where the colour has flaked off; I am still unsure how the "glue chip" surface was made -- even at areas where the colour has flaked off there is still the surface structure left, so it should be the glass itself and not another layer of coating (but I cannot guaranty that).

I guess it was produced this way to mimic better French acid treated glass from the 1920s/30s. But by whom and when?

Thanks,
Michael

Glue chip is done by coating the piece in hot horse hoof glue. When it cools it contracts and takes some of the surface with it. It was popular in Belgium n the 1930s, but has also been used in France and the US. No clue who else tried it...

Great, thanks a lot!
It is Inwald, "Orlow" range.
I found this interesting issue of Pressglas-Korrespondenz, showing the matching vase with the same decor: http://www.pressglas-korrespondenz.de/aktuelles/pdf/pk-2009-3w-stopfer-inwald-vase-orlow.pdf (http://www.pressglas-korrespondenz.de/aktuelles/pdf/pk-2009-3w-stopfer-inwald-vase-orlow.pdf)

It seems to be made using "Wasserglas" (no idea how that is called in English).

Wasserglass is fish glue.

Thanks :)

As far as I have understood, the text in PK only says that "most probably" the decor was made using water glass; so Ivo may well be right...
Anyway, interesting finish I haven't seen before. Funny that all these items seem to appear in Vienna.
