I have a question regarding the Pyrex bottom stamps. I saw a mixing bowl at a thrift store that looked identical to a Cinderella gooseberry pattern, white on pink, except the pink seemed a bit dark, and the bottom stamp was a crown. I didn't buy it, but I'm still wondering if it is Pyrex or Fire-King. I couldn't find any info on the web regarding a crown Fire-King bottom stamp or for any other brand for that matter.
Any thoughts? Did Fire-King or any other glass companies make a gooseberry-like pattern? Thanks!
