In 1968 a new ceramic translucent china body began to be used for Character jugs, something that continued until 1973 when there was a return to the traditional earthenware body. The new ceramic body necessitated some existing jugs to be re-modelled to ensure that the level of detail remained. Earthenware is decorated underglaze thus more depth is achieved upon the much finer-detailed, cast piece, whereas the detail is somewhat subdued once the glaze is applied for on-glaze painting. In general the new body produced jugs that were 1″ smaller overall with 19% shrinkage as opposed to just 12.6% with earthenware. Collectors search out these now rare editions of their favourite jugs as the overall effect creates a higher quality product in their eyes.
