Hi, I bought this bowl today, it's in what I think is its original box. It's nine cms tall, it's heavy and quite thick. Beveled round the outside top edge, and a very smooth bottom. 😃 It glows yellow under UV light. It has a round gold foil label that says "foreign", I don't know where to start looking for an ID. I thought maybe Czech but I really don't have a clue. Any thought. Appreciated. Thanks Cheryl.
