water jugs old that were made of sandstone and outside is metal?
Within these pinic stoneware jugs were the same as Redwing pots were made.
Tin glaze reached England via the Netherlands to 1550. At first it was called gallyware, but with the rise of the manufacturing center of Dutch Delft pottery came to be called Delft. Its popularity was due to the fact that it could be painted in bright colors. The first examples have survived are the Malling jugs, so called because a early specimen of nature has been preserved in the church of West Malling, Kent. They were almost certainly made in London. The color varies from turquoise to black, a variety with a blue background speckled with Orange was probably suggested by the tigerware of the Rhine. The pitchers are usually silver and pewter frames. Similar fixtures, often made in England, are seen in Rhenish jugs imported into England and occasionally Turkish pitchers on approximately the same period.
