Akro Agate
I have assumed for years that the bowls shown below were made by Akro Agate, based solely on "The Complete Line of Akro Agate Co.," written by Roger and Claudia Hardy. However, I visited with Roger Hardy in March 2010, and he told me then that he no longer believes Akro Agate made these bowls.
He said his original information came from one former employee and that he has since found recollections such as those to not always be accurate. He also bases his opinion on the fact that with their enamel-fired color over a translucent white base, they do not look like any other ware made by Akro Agate and that, in fact, they do much more closely resemble products made by Hazel-Atlas, a glass manufacturer also located in Clarksburg, WV.
Therefore, please consider that the manufacturer of these flips is unknown, with the possibility that they were made by Hazel-Atlas. I will leave this page here for now as an opportunity to try to undo some of the damage that this misunderstanding has caused. However, Akro Agate did make at least one ribbed flip from slag glass because it is on display in Hardy's museum of Akro Agate glass.
The following is the original text about Akro Agate flips. These flips do stand as a unit, in two sizes and made by the same manufacturer, but that manufacturer is now unknown. So disregard all references to Akro Agate:
Akro Agate flip-top containers were made in two sizes. It is a widely held belief that the company produced only three colors, plus clear: pink, yellow and a sky blue. In fact, we have found many, many more examples than that. Apparently the Akro-Agate Company stopped all production in 1949, but we do not know the years that these were made. Unlike most of the flip-tops, it is unusual for the lids on Akros to be pressed on; they can usually be twisted off for cleaning.
