Glatz Majolikafabrik
Mönchweilerstraße 1, Villingen, Baden. (now Villingen-Schwenningen, Baden-Württemberg.)
Kunst-Töpferei / Art Pottery.
He produced luxury goods, in earthenware of all kinds, Old German exhibition pieces and Old German and modern earthenware ovens fully decorated.
Villingen & Schwenningen were two separate towns until 1972, when they joined with several outlying villages to form the city of Villingen-Schwenningen.
The area was notable for the number of clock factories.
Johann Glatz commenced manufacturing in 1870. Situated in the Black Forest, he produced "Hafnerware" a type of Majolica. This he exhibited in 1893 in Chicago. Throughout the active life of the pottery he employed just ten people. Production continued through to his death in 1915. The company was wound up in 1916. Much of his Majolica range was designed by Professor Keller-Leuzinger, who brought the methods of production from Switzerland. `
