Kurze Beschreibung sämmtlicher, bey dem Churfürstl. Sächsischen Amalgamirwerke auf der Halsbrücke bey Freyberg vorkommenden Arbeiten
A German technical description from 1802 by Charpentier, published by Crusius, of the works at the Electoral Saxon amalgamation plant at Halsbrücke near Freiberg, written for mining and metallurgy readers. Its pictures are small seals and stamp-like emblems: a dark oval seal with faint lettering, a framed crest with a crowned figure and flanking statues, and a red wax seal of a standing figure, offering a designer compact emblem and seal motifs.
