Frosted Tin
A frosted appearevaporation. If there be a residuum, and bichloride of tin. dilution with water occasions a heavy white 3322. Το Make a Tin Tree. Dissolve precipitate, the tin contained bismuth. If, 3 drachms muriate (chloride) of tin in 1 pint after dilution, the addition of a solution of distilled water, adding 10 or 15 drops nitric sulphate of ammonia or of soda produces a acid; and suspend a small rod of clean zino in white precipitate, the tin contained lead. If a phial containing the above solution. red prussiate of potash gives a blue precipitate, it contained iron; and if the clear liquid leaves a residuum on evaporation, it contained copper.
