Hello,
I thought I would write back to say I resolved the "nut cup" question. I was on a board for glass collectors from the UK. I figured if I couldn't find any information then I need to try a shot across the pond! It appears these little pretties are simply souvenir cups and still made today. Basically what I have learned is this:
They are probably Bohemian made, with a technique used called "raised enamel and gold" (if they were Italian made they would be turbo furoco), the gold is probably 24k (she said almost always gold building is 24k), each layer would have required an annealing round (to heat up and cool slowly process), the producer over the years has been Egermann and the responder to my question said he would not be surprised if it was Egermann manufactured. Similar items have been around since 1880's. Unfortunately, in collectors terms they are not considered valuable.
That last part he did not expound on so I have no idea on a price point. Anyone have any thoughts on a price? I have one on my website, RefreshedForYou. They are very lovely when they are all polished and displayed.
Thanks for your help.
