Improved Electric Amalgam

It is well known that a deposit of moisture greatly interferes with the action of electrical Substances formed machines, experiments often wholly failing by mixing quicksilver with another from this cause, especially in the winter metal. Alloys containing quicksilver. Mer- season. Mr. F. Dietlen, of Klagenfurt, has cury unites with most of the metals by mere devised a method by which he obviates this contact, forming amalgams. These are em- difficulty, consisting simply in a modification ployed for various purposes in the arts, as of the amalgamation of the rubber cushion. silvering , gilding, coating mirrors, &c.

For this purpose he pours petroleum over 3533. Amalgam of Gold for Gilding zinc filings, and adds an equal quantity of Brass, Copper, &c. Place one part grain mercury (though an excess of mercury facilior leaf gold in a small iron saucepan or ladle, tates the process). The mixture is then perfectly clean, then add 8 parts mercury, and brought, by working together in a mortar, to apply a gentle heat, when the gold will dis- the condition of a homogeneous paste, and solve; agitate the mixture for one minute pressed between a double cloth. A soft mass with a smooth iron stirrer, and pour it out on is thus obtained, which, however, soon harda clean plate or stone slab. When cold it is ready for use.
