Raku Ware and Staffordshire Pottery
Uploaded by donovanglass on Sep 12, 1999
Raku Ware was originally from Japan in the town of Kyoto and was named after the Raku family during the 16th Century. At this time, the Emperor Hideyoshi had conquered Korea and the native potters immigrated to Japan bringing with them pottery techniques and knowledge.
The pots were produced for the Zan Buddhist tea ceremony and the decorating and firing of the pots were part of the tea ceremony. Bernard Leach introduced Raku into the west after living in Japan and China setting up pottery in St. Ives, England in 1920. It is still popular today, and made almost worldwide. Raku Ware is still produced today by the 14th generation, of the same Japanese family.
Staffordshire was a large and important part of Britain for earthenware production. The first known examples of Staffordshire slipware date back to early Seventeenth Century. Even though lead-glazed earthenware seemed to be established before this time, the market generally went beyond Staffordshire. Butter pots made in Staffordshire were well known for their quality by dairy farmers in England and surrounding areas. Slipwares are named for their decoration with liquid clays, usually poured or trailed onto the pot. Although this was a highly developed technique in Staffordshire it was used in other surrounding areas such as London and Wrotham.
Staffordshire slipware usually has three categories flatware which are plates, dishes and bowls, jugs and lidded pots are classified as hollow ware, and miscellaneous ware includes money boxes, cradles and candle sticks.
Just as tea was important in the development of Raku Ware in Japan, so the Elers brothers who studied salt glazes in Europe and moved to Staffordshire in the 1690s, produced small tea pots, tea canisters, teacups and jugs. They used finely prepared red clay which was thrown on the wheel, and then lathed when leather hard. (Common salt is thrown into the kiln during firing 1200oc to produce a salt glaze)
In Raku any clay that copes with the firing technique must be able to withstand heat shock without warping, distorting or cracking. The clay needs to have particles in it to allow water to escape quickly so calcinated China clay or clay with temper (grog, flint or shell) added to it, is successful. This clay occurred naturally in Japan. Many contemporary potters have favourite clay recipes for their clay bodies when making Raku Ware.
