Johann Friedrich Böttger

[Paul Ferguson]

'The arcanum for porcelain was deeply coveted by European nobility along with the ability to transmute ordinary metals into gold. The latter pursuit led Augustus the Strong to summon the alchemist Johann Friedrich Böttger to his palace in Dresden in 1702, in a bold attempt to discover the formula for the philosopher’s stone. Unfortunately for Böttger, the task was undeniably impossible, resulting in a series of failed experiments, unsuccessful attempts to flee, and his forceful recaptures.
Böttger’s luck turned around in 1708, when he was able to appease Augustus the Strong by successfully producing the first Continental European hard-paste porcelain, also referred to as white gold.'
