Title: Sklo Union glass question - were any ever produced in
Post by: flying free on May 06, 2021, 07:47:55 PM

red?

I love all the colours but on re-arranging my display this evening a question that's played on my mind forever came up again - no reds?
To be honest, the display has most of the colours and I have a red vase in it from elsewhere  but it looks odd - it doesn't work with the other colours.  I'm sure that's not the reason why I've never seen a red Sklo Union vase though.

Interesting, never noticed before. A case in point? - https://www.clutterfingers.com/listing/636366919/rosice-sklo-glass-lens-or-bullet-vases

It's been on my mind since I started my collection about 8 years ago  ::) but for some reason I've never asked.
I'm musing here - I guess contemporary/20th century red is maybe either gold ruby (e.g Whitefriars), copper ruby, or selenium?
There seems to be some mid century Scandinavian mold blown glass in red.  I have a couple- think  Aseda - and  think Riihimaaki used a red - I've kept them because I quite like the shapes but can't afford the real Scandinavian mid century avant garde shapes so never made a collection.  I don't think it's gold ruby but I suppose maybe copper ruby.
I think some Scandinavian makers used selenium and also I think there is some Russian and Ukrainian glass which used selenium?

So I'm assuming red is difficult to work with ( I think ?) but it's really strange none are in the Sklo Union sets. Is it difficult to produce consistent colour and also expensive maybe?

Perhaps cost or prevailing fashion would be the biggest factors, I suspect workability might be less of a reason in this case.

mm, been thinking.  I think red needs to be cased because of the depth of the colour. That wouldn't be possible with Sklo Union pressed pieces would it?

Pressed glass doesn't mean it can't be red. Davidson made it but it may have been a cost thing as there was apparently a shortage of selenium post War http://www.cloudglass.com/davidsonpostwar.htm

Thanks for the link and info Christine.  Very interesting. 
There's an interesting timeline of Sklo Union glass production here (I think?)
https://www.sklo-union.eu/history
It seems the Sklo Union pieces were produced for a long period.

Quite possibly cost of and shortage of selenium then as using gold ruby or copper ruby may have necessitated it being cased which wasn't possible on mass production glass?
