Works
Late in the seventeenth century, he was charged with making a survey of the minerals of Saxony. He had a government position there.  He and his assistant, Johann Friedrich Böttger, discovered how to make porcelain. Schönfeld, Martin  (October, 1998) "Was There a Western Inventor of Porcelain?"

Before that, it had only been made in Asia.

Tschirnhaus's work in mathematics is remembered in the Tschirnhaus transformation. It removed some intermediate terms from a given algebraic equation.  He is also remembered in the Tschirnhausen cubic.

His work in physics included work in optics. Working  with Martin Knorr, he developed an improved polishing technique. This was used in the lenses and mirrors he made. He made burning glasses of high quality. He used these in experiments.Winderlich,Rudolf (1949) Winderlich"Brenngläser als Hilfsmittel chemischen Forschens," Chymia, 2:  37-43.
