This sweet little Jade-ite Demitasse Cup by Fire King is in the vertically ribbed Jane Ray pattern. Jane Ray is recognizable by its vertical ribs that encircle the cup and stop just 3/8 of inch from the top forming a smooth band.
This charming little Demitasse Cup measures just 1-5/8 inches tall and 2-5/8 inches in diameter at the rim. The foot is 1-3/8 inches in diameter and the handle adds another 3/4 inch.
The embossed mark reads "Fire King" between the words "Oven Ware" followed by the number "14 Made in USA." Jane Ray was made by Anchor Hocking from 1946 to 1965.
There is a manufacturing flaw that looks and feels like a scratch in the center bottom. The brown spot in the photo has been removed.
