This is a beautiful round plate, approximately 21cm in diameter. It's an elegant piece by the Imperial Glass Company, featuring open lace edges and a diamond pattern on blue opalescent glass. The plate reflects light at different angles, creating a milky white gradation that truly embodies art glass. #yupi123's Listing When exposed to a blacklight, it softly fluoresces, allowing you to enjoy a fantastic glow similar to uranium glass or vaseline glass. *Note: Even among similar items, not all fluoresce, so I've confirmed this with a 365nm blacklight.* This is Depression glass, popular in the United States in the 1930s, and is also recommended for those who appreciate the texture of milk glass or opalescent glass. There are no noticeable scratches, cracks, or chips, and it's in quite good condition considering its age. You can see characteristics from the manufacturing process, such as press lines, slight distortions, unevenness, and air bubbles, which are part of the charm of old glass. Due to the delicate design, there may be minor scratches, chips, or dirt that I haven't noticed, but I hope you can enjoy it as a vintage item. Photos were taken with an Android device.
