Until the late 19th century iron oxide pigments were obtained wholly from natural materials, generally with little alteration other than physical purification. In some cases roasting or calcination was also carried out. However, beginning in the first part of the 20th century, chemical methods were developed for synthetic production of commercial …

Waldenstein ore contains a natural iron oxide (Fe2O3) which distinguishes it from other iron ores a.o. with its metallic grey luster. Its lamellar structure – resembling that of mica – has also given it its name. Through a process of drying, grinding, screening and cleaning, the rock, which is also known as hematite, is turned into a soft ...
