Title: Tall green opalescent vase - who, when?
Post by: KevinH on September 12, 2007, 12:07:08 AM

I have owned this vase (See here) (http://glassgallery.yobunny.org.uk/displayimage.php?pos=-8447) for over 15 years, but never found out where or when it was made. I have not seen another of the same size and shape. Any ideas on this are welcome.

It is 44 cm (15 7/8 inch) tall, diameter of base is 16.5 cm (6 1/2 inch) and the base section is 7 cm (2 3/4 inch) high. Weight is 2.27 Kg (5 lb).

Rim view (http://glassgallery.yobunny.org.uk/displayimage.php?pos=-8446)
Profile of base (http://glassgallery.yobunny.org.uk/displayimage.php?pos=-8445)
Finish of base (http://glassgallery.yobunny.org.uk/displayimage.php?pos=-8444)

As seen in the overall view, when lit from the back, it has a typical orange glow seen in most opaline glass. The base, however, being thicker than the neck does not show the glow except under very strong light. The opalescent rim is clearly visible in most lighting, including camera flash. Strangely (?) the ground out pontil area also shows the opalescent colour even though there is little light entering that part and the glass is quite thick in that area - in fact, at a casual glance, it appears to be a pastel blue glass overlaid with green!

If the item is made by 'striking' you might well be looking at zinc oxide glass - a Russian/ Ukrainian speciality made in many shades of colour plus opaque. In which case you are talking about a relatively heavy item.

Thanks Ivo, that's an interesting thought. The rim certainly looks to be made by striking and I guess the colour of that part could well be "zinc-influenced". But I'm still puzzled about the colour showing at the ground pontil area!

I noticed in your Glass Fact File a-z that you mentioned "zinc sulphide glass" and two of the folk connected with it. Would that be the same as the "zinc oxide glass" in your comment here?

I have the book Russian Glass of the 17th to 20th Centuries and it is clear that there were many Russain items that could easily be assumed to be European. I wish there was more literature on Russian glass. It's much the same as with paperweights, where some items have now been shown to be Russian but there is nothing on the general production (at least, not in English!).

1st of all, sorry i meant zinc sulphide glass.

In addition to the work you mentioned I have "Soviet Glass"and "Gus Krushtalny". The latter has none, but the Soviet glass book has many examples of this type of glass. Usually the items are a bit garish - your vase is a miracle of restraint by comparison. And it seems many Russian glass artists used this material.
