Fire-King mark
Fire-King is Anchor Hocking’s trade name for heat-resistant glass ovenware, and later dinnerware, made from 1942. The mark on the base takes several forms, most often a script Fire King between the words Oven and Ware; Anchor Hocking still owns the name.

How to read it
Fire-King was the trade name of the Anchor Hocking Glass Corporation of Lancaster, Ohio, for glass that could go in the oven. Virginia Scott, writing in Glass Review in 1981, dated the first production to 1942 and found the earliest advertisement in Good Housekeeping for October 1942; the first pieces were pale transparent blue, pressed with scrolled medallions joined by ribbons. Scott found in the Trademark Register that the name Fire-King was registered on 24 June 1941. Anchor Hocking still owns it: Anchor Hocking LLC’s website lists Fire King among its trademarks, and the company sells Fire King bakeware.
Also searched as: fire king, fire-king, fire king oven glass, fire king oven ware.

The marks on the base
Scott described the variants. Some early transparent blue Fire-King was unmarked, as far as she could find; other blue pieces have FIRE-KING in block letters. The commonest marks have a script Fire King with OVEN above and WARE below, sometimes with MADE IN USA added and sometimes with GLASS in place of WARE; on table pieces the word can be DINNERWARE. Another version puts the words Anchor Hocking and the anchor-H in a circle, and some pieces have the anchor-H alone.
Colours and dates
Scott’s dates, partly from Earl Lifsey’s The Housewares Story: light blue from 1942 to 1945; Jade-ite, an opaque jade green, from 1945; Azur-ite, an opaque light blue, a little later; ivory from 1948; crystal and white from 1951. White Fire-King was decorated in many colours and designs, and complete dinner sets were made in Jade-ite, Azur-ite, ivory and white.
The F in a shield
The Anchor Hocking Glass Museum notes that an F in a shield is often taken for Fire-King. It is the mark of the Federal Glass Company of Columbus, Ohio.
