Soldering

 Neat Mode of Soldering

Cut out a piece of tinfoil the size of the surfaces to be soldered. Then dip a feather in a solution of sal ammoniac, and wet over the surfaces of the metal, then place them in their proper position with the tinfoil between. Put the metals thus arranged on a piece of iron hot enough to melt the foil. When cold the surfaces will be found firmly soldered together.
