Over the course of time I have seen and heard of Flow Blue. It’s a type of transferware that was very popular in the early and mid-1800s and is still highly collectible. According to Collectors Weekly, Flow Blue pottery began showing up in the 1820s in Staffordshire England. It was created when lime or ammonia was added to the kiln during the glazing process. The chemical caused the blue transferware to run and blur which many people found desirable.
I, personally, love many of the Flow Blue patterns; I find them very pretty and unique. I didn’t, however, realize there were other colors until I ran across these amazing saucers.
In researching them, I could see they are marked “Wedgwood” and “Pearl Stone Ware.” They are also marked “Washington Vase” which turns out to be the pattern name. But these are not Flow Blue, they are Flow Black! And gorgeous!
These date back to about 1860, so they are over 150 years old. There was a bit of yellowing on a couple of them but you can see one that I believe was the original color. It was a white glaze with a black transfer that was “blurred” in the creation of the Flow Black pattern. The earliest Flow Black Washington Vase was done by a company named Podmore, Walker & Company (PW & Co.) which then became Wedgwood around the 1860s when Enoch Wedgwood became the senior partner during the acquisition of PW & Co.
You will see the PW & Co. mark on Washington Vase from the early 1800s and then around 1860 you will see it marked Wedgwood using the same backstamp, an oval and ribbon. Pearl Stone Ware, which is the other mark on these saucers, was marketed by PW & Co. as a more durable earthenware, being fired at a higher temperature. Since these particular saucers managed to hang in there for 150 years, I guess that it is pretty strong!!
You will sometimes see Flow Black referred to as Mulberry. I saw black but perhaps others see a slightly maroon tinge.
I hope you have enjoyed learning about this beautiful transferware and will be able to identify it when you see it. It’s very collectible! If you have any stories about your Flow Black or Flow Blue, leave me a comment. Have a great week!
