This is a Fire King white swirl milk glass cup with gold trim. Fire King is a brand of heat-resistant glass products manufactured by the Anchor Hocking Company. Especially the milk glass tableware gained popularity for its unique texture and durability. "White Swirl" is characterized by the swirling pattern on the side of the cup. The design with gold trim (gold paint) gives an elegant impression. Although it is made of heat-resistant glass, care should be taken with sudden temperature changes and strong impacts. The use of microwave ovens and dishwashers, which were not anticipated at the time of manufacture, is not recommended. I purchased it at an antique shop in the United States and have kept it in storage without using it. There are no noticeable scratches, and it is shiny and beautiful, but please understand that it is a used item.
