"Westerwald Pottery or Stoneware is a distinctive type of salt glazed grey pottery from the Höhr-Grenzhausen and Ransbach-Baumbach area of Westerwaldkreis in Rheinland-Pfalz, Germany.
It is known as Kannenbäckerland Stoneware. Typically it is decorated with cobalt blue painted designs, though the collectable items are more multicoloured.
There is a pottery museum at Höhr-Grenzhausen that displays the construction techniques and the history of salt glaze." - (en.wikipedia.org 11.08.2021)
