Germany, 1812

To outfit a scientific glass laboratory at Jena, Goethe gave a summary of the supplies and purchases for the year 1812.  Item six on this list relates to platinum equipment costing a total of Rthlr 113.0626 ~ Fr. 412., which presumably included transport/handling costs.


1810/1: 1 Troy Oz. Platinum (Paris: Mfg, Ret.) ~ Rthlr 10.04 (Fr 36.6)

Finally he transferred the responsibility for the Dobereiner laboratory to his son Julius August Walter von Goethe (1789-1830), who had studied law at Heidelberg and Jena, and who became an indispensable assistant to his father. Part of the detailed instructions written to the son on 28th April, 1812, states:

“If the equipment arrives from Paris, the Court commissioner Ullmann has orders to send them to Prof. Dobereiner in Jena and hand the bill for them - which may be near 70 Rthlr [Reichsthaler] - to His Excellency der Geheime Rath von Voigt asking him to be so kind as to authorise it with the addition of the separate account.”
 
In a report to the main control agency dated November 22nd, Goethe gives a summary of the supplies and purchases for the year 1812. Item six on this list relates to platinum equipment costing a total of 113 Reichsthaler, 2 Groschen and 8 Denar, a Denar being equivalent to a Pfennig.

Herr Frick, Arkanift the Porcelain Manufactory in Berlin, has entered a new mode of proceeding to present the cleaned platinum in solid pieces. He says the same about the following:

If you have cleaned the crude platinum by dissolution in aqua regia and precipitating with ammonia, so it was difficult until now of the annealed Platinaniederschlag melted into a continuous whole or welded together to represent.
