 entweder sofort in Benutzung genommen oder lange Zeit hindurch in trockenem Zustand aufbewahrt worden, ohne dass die Flächen. angefressen werden. 



   Der molekulare Zustand des Materials erleidet durch diese Behandlung keinerlei Änderung, da die Säure nicht in die Poren eindringen kann und die Reste der Säure, die dem Gegenstande noch anhaften, durch Alkalien neutralisiert werden. 



   Zur   Durchführung   des Verfahrens wird in dem ersten elektrolytischen   Gefäss   eine

 Teilen der sehr energisch wirkenden Salpetersäure besteht. Als alkalisches Bad wird vorteilhaft eine Lösung von drei Teilen Ätznatron und einem Teil schwefelsaurem Natron

   This treatment does not change the molecular state of the material, since the acid cannot penetrate the pores and the residues of the acid that still adhere to the object are neutralized by alkalis.



   In order to carry out the method, one is in the first electrolytic vessel
