A lovely Glasbake casserole dish with a blue flower pattern (I have seen this pattern called Blue Snowflake, Blue Daisy, Blue Flower Dot) & oval shape! Glasbake was introduced as an alternative to Pyrex & has the same ‘fridge to oven’ idea! Great condition with minimal wear. The history of Glasbake is more complicated. According to the Florences, this brand was introduced as Glasbak Ware by McKee in 1917, then in 1951, it became Glasbake, by the McKee Division of Thatcher Glass Corporation & continued until 1961. From 1961 to 1983, it was Glasbake by Jeannette. Glasbake made by Jeanette after 1961 usually have a J prefix followed by a number on the bottom of each piece.
