Glass Message Board

From the ground rim finish and the yellow enamel under the gilding, I would say Bohemian/Czech. No idea on date though but probably pre WW2

Additionally, the actual dressing table set which is the main topic of the thread is now identified as Sowerby Pattern 2707;

also I think from reading the reports,that it seems unlikely there would have been much American glass over here in the UK in that late 19th century period.
The report seems to ask how they can increase their exports to the various countries and the answer seems to be ... produce the products people want in that country,  produce them on time, ship them on time and with packing rates that are comparable to competitors in Europe and have sales people over in the countries to sell the items. 
The few I've read don't seem to indicate there are any insurmountable trade barriers in comparison to other countries so trade agreements/import tax doesn't seem to be the problem.  It does appear that they were trying to find a way of increasing their trade with European countries.

Therefore, along with the design indicators, I'd say the opaline vases in this thread are more likely to be French than American?

They did register patents but I don't know about designs.

Baccarat was marked from ? maybe late 19th?
Saint-Louis is marked as well.

I remember a thread on here years ago where Bernard commented on it.  The fact that glass factories didn't mark their items and how astonishing it was that someone would produce some fabulous art glass vase and it would then go out without makers mark on. By comparison to pottery/china and silver it is actually quite shocking.
