Here is an elegant glass Bow Handle Bon Bon by Fostoria in beautiful Mother of Pearl Iridescence on the Fairfax blank. Fairfax is blank No. 2375 which was used for many Fostoria etchings, but the Mother of Pearl color on clear glass is pretty enough on its own. The decagon shape is formed by subtle ribs coming to a small point creating ten panels. A pair of bow-shaped handles draw up the sides and extend down the panels with three ribs that form a triangle.
Fostoria Stemware, Second Edition, by Milbra Long and Emily Seate places The Mother of Pearl color in production possibly as early as 1916, and not later than 1928. If this information is correct, it could explain why this iridescent color is not often seen. However, numerous other sources offer dates into the early 1940s. It is unclear whether this information may be based on the Fairfax pattern, rather than color, since Fairfax was in production from the late 20s into the 40s. So, we know this dish was made sometime between 1927 and 1943. There is no mark.
This lovely candy dish measures 6-7/8 inches long by 5-1/ 2 inches wide. The handles curve up to a height of 2-3/8 inches.
There are numerous surface scratches, seen mainly when held up to the light, but no chips or cracks.
