I have a water pitcher and basin that I find rather ugly, other than the nice skin color “crackling” on the bottom. A “trader” apparently brought it back from Indonesia when we lived in Australia (about 1966). It seems to be made in a popular pottery town of Burslem, England, based on the mark on the bottom that says: “The Burslem Pottery Co” (England, Spectis). I’m not sure what “Spectis” means.

Apparently this company made pottery from 1894-1933.
