subterraneous production* brilliant, reflective, sweetly sonorous, not affected by common acids.
1. " Malleable." Silver can be reduced to a thinness nearly equal to that of which gold is capable.
152 FIFTH SERIES.
2. " Ductile." It can also be drawn out to the finest wire.
3. " Tenacious." A wire one-tenth of an inch in thickness will support 277 pounds without breaking.
4.... " Weight." It is about eleven times heavier than water.
Uses of Silver.
Silver is combined with copper for coin, to render it harder and better adapted to receive a fine and sharp impression on being cast. The same alloy is employed for ornamental purposes.
Silver is used much as a casing to copper uten- sils, to prevent the injurious eflects of acids, or to render them more pleasing to the sight. The most permanent plating is effected by taking two thin plates of silver and copper, the former in the pro- portion of one to twelve of the latter ; a little pow- dered borax is placed between them to promote the fusion of the two metals, which after being exposed to a white heat, will be found firmly united; this is passed between rollers till the whole is of the proper thickness for the intended manufacture.
