Porcelain
Von Tschirnhaus and his assistant Johann Friedrich Böttger were employed by Augustus the Strong and worked at Dresden and Meissen in Saxony. A workshop note records that the first specimen of hard, white and vitrified European porcelain was produced in 1708. At the time, the research was still being supervised by Tschirnhaus, who died in October of that year. Böttger reported to Augustus in March 1709 that he could make porcelain. He usually gets the credit for the European discovery of porcelain.
