As a River Flows, So Does Flow Blue

QUESTION: My mom loved collecting odd pieces of old china. She died recently and now I have her collection. Among the many pieces are some with designs that are all dark blue and blurry. Are these mistakes or are they some sort of china I’ve never heard of?

ANSWER: No, those blurry pieces are not mistakes. They’re what’s known as Flow Blue. And while many people call this type of ceramics “china,” it’s actually pottery not porcelain. Beginning in 1820, potters in Staffordshire, England, began making it as a way to provide a more affordable alternative for middle-class people who coveted the fine blue and white porcelains being imported from China. As dinnerware, it enjoyed its greatest popularity between the mid-19th century and the beginning of the 20th century. And as an antique, it has gained popularity in recent years.

Potters used cobalt oxide pigment to create the darker hue of flow blue. The porous earthenware absorbed it and blurred when the pottery glaze fired. Although it blurred by itself, potters discovered that it could be made to really flow by the addition of a cup of lime or chloride of ammonia during glaze firing. This had the additional advantage of covering over printing faults, bubbles, and other defects in the pottery. As a result, some flow blue is so blurred that all details are invisible.

Josiah Wedgwood first produced Flow Blue around 1820. But it wasn’t until 15 years later that mass production began. Since flow blue was a decidedly Victorian era phenomenon, its production fell into three time periods.—early Victorian from 1835 to 1850, mid-Victorian from   1860 to 1879, and late Victorian from 1880 to 1900. During the early Victorian period, the most popular styles imitated the Chinese porcelains. But they were largely inaccurate depictions of the Chinese designs, mixing Chinese, Arabic and Indian motifs. Scenics and florals were also  popular during this time.



The mid-Victorian period brought greater creativity to Flow Blue wares, as potters mixed styles and ornamentation became elaborate and varied. Also during the mid-Victorian period, styles began to mix and merge with one another. So, there were things like Oriental-style plates with floral, Gothic, or scenic borders. Other elaborate motifs, like scrolls, pillars, columns, urns and wreaths became quite common. The pieces themselves included toilet wares and teapots, plates and platters, vases and garden seats, and even dog bowls.

Flow blue designs of the late Victorian period exhibited a marked Art Nouveau influence, with stylized florals and beautiful symmetry.

By the end of the Victorian Era, there were thousands of Flow Blue patterns. Though most Flow Blue wares came from English potteries, those in Germany, France, Belgium, the Netherlands, and the United States all made it as well. The most noted English potteries included such names as  Wedgwood, Grindley, Davenport and the Johnson Brothers, while in the United States, Wheeling, Mercer, and Warwick. 
By World War I, U.S. potteries were producing most of the flow blue for the domestic market, causing English potters to close up shop since these wares had never been popular in England. The desirability of the ware waned in both countries between the wars, but interest picked up again in the U.S. in the 1960s.

Antique dealers determine the price of Flow Blue wares mostly based on their pattern, color, and rarity. Patterns range from Blue Danube to Iris and Classic Willow. Especially sought after ones include Amoy, Cashmere, Scinde, Shell, and The Temple, as well as the La Belle pattern by American maker, Wheeling Pottery Company.

Collectors are always on the hunt for the early patterns from the 1840s. Unusual items such as rare shapes, egg baskets and egg cups, large sized platters and early tea and coffeepots command high prices. Egg baskets with eggcups will fetch over $1,000. A single eggcup in a rare pattern can fetch over $400, whereas a not so rare one would fetch maybe $65. Rare coffeepots could he worth over $2,000, and large turkey platters from the 1890s, $600 to $800 if the pattern is right.
