Fire-King Jadeite Flat Bottom [GLASS Logo] Mug #002. *This item was purchased in the USA. ⭕This is a rare early D-handle mug manufactured between 1946 and 1951. It is also called a flat-bottom (or shaving) mug due to its completely flat bottom design. Compared to later D-handle mugs, it uses more milk glass and has a stable weight, making it very comfortable to use. The color is Fire-King's signature "Jadeite." This is recommended for those who like older antique Fire-King items. By the way, flat bottoms were only made in ivory and jadeite in the early period. Turquoise and white made after that do not have a flat bottom. The condition is excellent, with a glossy surface and very few scratches or stains. The mark on the bottom of the mug is "OVEN Fire-King GLASS." We ask that those who understand and appreciate antiques consider this item. ◆Condition◆ No chips or cracks, glossy, and all in beautiful condition.
