1916 - Production of grinding wheels

After the outbreak of World War I in 1914, the demand for pottery and porcelain decreased slightly at first and then dramatically as the War continued. In 1916 the focus is placed on the new product segment of grinding wheels.

The industrial requirement is significant and the business grows rapidly. Recognising the signs of the time, Walter Guilleaume and his brother-in-law, Dr. Otto Goertz, set up a separate department for producing grinding wheels in the existing company. The vast experience gained in the production of ceramics stand the company in good stead for developing the grinding wheel sector.
