Brown Tulip and Gingham GlassBake Mugs

Today I went out antiquing and fell in love with these milk glass mugs with a brown tulip and gingham pattern on them. Since I had never seen anything with this pattern before, I had to research it!

A Little Background on Glassbake

At first I thought they were Pyrex, but they are actually Glassbake, a cousin of Pyrex. In 1917 The McKee Glass Company debuted their Glassbake ovenware as a competitor to Pyrex ovenware, a brand by Corning Glass Works. The name of the company comes from the founder, McKee Glasbak. Glasback was the original spelling for McKee's ovenware, but was changed to Glasbake sometime later.

They made this bakeware in a variety of fun and funky colors that aligned with popular kitchen design colors back in the day.  

While they do not make this kind of bakeware anymore, there are some very nice  options like the Pyrex Simply Store Pure Glass set. patterned bakeware by Pyrex, such as this Pyrex Simply Pure BPA-Free Glass Set. There are also some really nice vintage style bowl sets by Pyrex that are adorable!
