When perfectly dry, pulverize, and it is ready for use. With a little trouble you will obtain in this way a much better article than can generally be bought of dealers. For the last washing, alcohol, or a mixture of alcohol and water, is preferable."英文原著 · 《American Hand Book of the Daguerreotype》
Bromide of Starch.--This preparation is much used, but not alone. It is combined with lime by putting about one part in measure of starch to four of lime. It is prepared by adding bromine to finely pulverized starch, in the same manner as bromide of lime. (See Accelerators.)英文原著 · 《American Hand Book of the Daguerreotype》
Experiment.--On projecting dry pulverized iodide of potassium into fused anhydrous phosphoric acid, a violent disengagement of iodine takes place, attended by a transient ignition; fused hydrate of phosphoric acid liberates iodine abundantly from iodide of potassium; this reaction is accompanied by the phenomenon of flame and formation of a considerable quantity of hydriodic acid.英文原著 · 《American Hand Book of the Daguerreotype》
Lime Water Quick.--This mixture is more used at present than all the other liquids ever introduced. It produced the most uniform results, giving the fine soft tone so characteristic in pictures produces from accelerators containing chlorine. To one quart of lime water (this can be had of any druggist) add one and a half ounce of pulverized alum. This should be shook at intervals for twenty--four hours; then add one ounce of chloride of iodine and three fourths ounce of bromine.英文原著 · 《American Hand Book of the Daguerreotype》
Take rain water one quart, add pulverized alum until it is a little sour to the taste, and a small piece, say one half inch square, of magnesia. Filter through paper, and add chloride of iodine one half ounce, bromine sufficient to take it up, which is a little less than half an ounce.英文原著 · 《American Hand Book of the Daguerreotype》
You write your sins on a clay pigeon, They fire 'em up in the air, And you pulverize them with a 12-gauge shotgun Full of our Lord's forgiveness.美剧 · 《The Big Bang Theory》
