Recently a collector contacted me to ask if I had ever noticed a difference in the color of the flourish above the birds closest to the handles on the 473 1 Qt. Round Casserole. I had not. She pointed out that the 473 casserole pictured in Pyrex Passion had a single red flourish above the bird, but hers had a double orange flourish. Everything else about the pattern was the same. This piqued my curiosity and led to digging through my Friendship casseroles as well as various reference documents. Sure enough, Corning produced two different Friendship 473 casseroles with this tiny design variation. |
Some digging through old catalogs and advertisements revealed a Mother’s Day ad which appeared in Woman’s Day magazine in May 1971, that shows the 473 casserole, as part of the 480 Set, with a clear lid and a double orange flourish. It’s tempting to conclude that the double orange flourish was produced with clear lids and the design was later changed to a single red flourish when opal lids were introduced. However, there’s currently no concrete evidence that the flourish design and lid changes took place at exactly the same time. What is certain is that the double orange flourish was being produced in 1971 and the single red flourish was being sold in 1973. |
