Semidiaphanam Tremuli Narcissuli Ideam Lacteam1: Ehrenfried Walther von Tschirnhaus (1651–1708) and His Determined Search for the Porcelain Principle

Archaeometry, Volume 68, Issue 1, Page 120-131, February 2026.
ABSTRACT With this contribution, an attempt is being made to chart the timeline of the invention of the European hard‐paste porcelain based on historical documents. They were evaluated to trace the development lines from Tschirnhaus's early experiments with burning mirrors and lenses in the 1680s to finding ‘wax porcelain’ around 1694 to the ...
