This item dates from the late Edo period to the early Meiji era. It is a Belgian cup plate (made around 1830-50), the same type as those imported during the late Edo period. It was made in Japan after the import of a press machine in the early Meiji era. Compared to the Belgian-made ones, the rim has been re-melted and is smooth, but the pattern is uneven and the glass has bubbles, so it cannot be called a high-quality item. However, its significance lies in the fact that it was made in Japan, and it is traded at a high price. The diameter is about 12cm and the thickness is about 1.5cm. There are no chips or cracks, and it is in a very beautiful condition. This is a famous pressed glass that is almost always featured when you look at books about glass. While many pressed glasses are colorless and transparent, the brown color is very rare. This is a piece that I would like to sell to someone who collects antique pressed glass. I purchased it 20 years ago from a famous antique dealer in Kyoto. Please feel free to contact me as if you were at an antique market. If you have any questions, I would be happy to answer them so that we can come to an agreement before the transaction. If you are satisfied with the photos and description, you can purchase it immediately. Thank you very much.
