I found my bowl on etsy while researching something else.
Haha!!
I learned this is Federal glass, and is the smallest bowl in a set of 3.
It measures 3.25" x 7.75"
It has no markings.
My question is...
Besides Federal and Anchor Hocking what other glass companies are there?
Too numerous to list?
I have many glass bowls of different shapes and sizes that have no markings.
Knowing where to start looking would be a tremendous help.
