In my pursuit of vintage, I frequently come across a sister to Pyrex known as Glasbake or Glasbak, depending on the vintage. I thought I would do a little research on this lesser known sister of Pyrex.
The Glasbake bowl above I picked up a few months back. On the bottom it is embossed “Glasbake Made for Sunbeam.” It was part of a mixer set. Turns out Glasbake was created in 1917 by McKee Glass Company to compete with Pyrex.
The spelling was originally “Glasbak” for “Glasbak Ware” but was changed somewhere in the first few years putting the name change somewhere between 1918 and the early 1920’s.
According to a very informative blog on the subject, C. Dianne Zweig, she says that Glasbake went through a few incarnations. It started as “Glasbak Ware” from 1917 to somewhere in the early 1920’s, to “Glasbake” until 1953.
It was then changed to “Glasbake by McKee Division of Thatcher Glass Corp.” from 1951 to 1961 and finally “Glasbake by Jeannette Glass” from 1961 to 1983. As a side note, Jeannette was not a person’s name but the name of a town. Jeannette, Pennsylvania was where Jeannette Glass was located. You can tell the age of your Glasbake … if it has a “J” pre-fix to the numbers, the “J” denotes Jeannette Glass Co. and puts the age of the piece after 1961.
As I said, Glasbake was meant to compete with Pyrex so you are able to cook with it and put it in the refrigerator. I am not sure about the microwave as it stopped production before the wide-spread use of microwaves.
Glasbake came in lots of different, colorful patterns; florals, fruits and seasonal motifs. They also created more than bowls. There were Hottles which could hold hot things.
There were measuring cups…
Individual covered casserole dishes and lots more! They were very creative.
You can also find Glasbake items under Flamex and Range-Tec.
I hope you have enjoyed this look at a lesser known brand that created some pieces that have certainly stood the test of time. Along with Pyrex and JAJ, you can add Glasbake to your cool kitchen collectibles!
