Found by accident
A few weeks ago when my mom was visiting, we scoured the internet for the pattern of a saucer that I like that I picked up at the thrift store several months ago. It's become my favorite from my saucer collection; the raised pattern and the opaque glass-like texture really piqued my curiosity.
Our only leads were the Anchor-Hocking mark on the bottom and my mom's opinion that it probably pre-dated her. Alas, though, we didn't find the name of the pattern.
I'd forgotten about our search today when, on a whim, I looked on eBay for jadeite. One of the first results that came up was this beautiful green saucer, which I immediately recognized to be the same as my little saucer, just in a different color.
Finally armed with the pattern name, I was able to find a full set immediately, and some information about the pattern. My mom was right, it does pre-date her: it was made in the 1940s. I'm glad to have finally satisfied my curiosity.
