Eisenporzellan

Eisenporzellan, or "iron porcelain," is a type of stoneware developed in Meissen, Germany, around 1710. It is known for being exceptionally hard, typically ranging in color from red to dark brown. A nearly black variety was referred to as Eisenporzellan, and a black glaze was created to cover pieces with color defects. Decoration was often applied in relief, and the black-glazed items were sometimes embellished with lacquer colors, gold, and silver.1

While Germany is renowned for its porcelain, its stoneware from the Rhineland is also significant. The earliest distinct German pottery style, dating back to around 1350, was Hafnergeschirr, or "stove maker vessel," which initially referred to decorative tiles for stoves. German stoneware, particularly from the Rhineland, was popular and even exported to Japan during the 17th century.1
