I noticed the brand mark on the bottom of the casserole is backwards. Is that how it's supposed to be??? Apparently so. I found this online on SPGlass's Fire King FAQ page-
Q: I have a pie plate with the Fire-King logo written backwards. Is this unusual or rare?
A: Unusual? A little. Rare? Definitely not. Some logos were intended to be read looking down, through the glass. When such a mold was used with an opaque slag, such as white, ivory or jade-ite, the backwards logo made less sense.
Stella from Our Vintage Life has a great collection of this pattern.wonderful little article on the Primrose Pattern. I learned from her blog that this pattern was only produced from 1960 to 1962.
Even though this pattern was only made for a few years, you can still find them and they aren't all that pricey. Click here to see primrose pieces on Ebay.
