hi, there is a fairly large explanation in the book about uranium glass. Unfortunately my French is not good enough to read and translate. It does appear to say that uranium glass came about in France by Bontemps for Choisy:
'En France, le ouraline fut redecouverte en 1838 par Bontemps dans sa cristallerie de Choisy-Le-Roi' pp12 BAGUIERS et VERRE A BOITE, L. Darnis
There are a number of transparent (not opaline) uranium glass pieces in the book, both footed bowl and also goblets. They date to 1838 - c. 1840s as far as I can see, but they are all very 'refined' and very symmetrical. None are like your glasses. None are a honeycomb molded bowl.
Sorry not to be more helpful.
