[QUICK STUFFS.]
We have endeavored to guard against giving useless receipts, thereby saving our Daguerreotypes a tax which would prove in most instances of no benefit. As many have requested us to publish a variety of receipts for Quicks. We give them with but little comment. We will number each combination:
No. 1. Take pure rain or distilled water, one quart filtered through paper into a bottle having a ground glass stopper, and add one and a half ounces of chloride of iodine for warm weather, or little less for cold weather. The reason of this is obvious, from the fact that during the warm summer day, the bromine is far more volatile than in a winter day. To the above add one ounce of best American bromine, and shake well. Now, with care, to prevent, as far as possible, the escape of gas, add, drop by drop, thirty drops of aqua ammonia, shaking well the mixture at each drop.
It is necessary that caution be observed, and not add more at a time than three drops of the aqua ammonia, as otherwise it evolves too much heat.
Use. Put in the box one part quick to eight parts water. Coat to dark yellow over dry iodine, and change to a deep rosed color over the Quick; recoat over iodine one-tenth.
No. 2. Lime water, one quart; chloride iodine, one ounce; add three-fourths of an ounce of bromine—shake well.
Use. Put in box one part quick to six water; coat to bright yellow over iodine; to rose over the quick, and recoat one-fourth.
No. 3. Take rain or distilled 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.
Use. One part quick to six parts water; coat over iodine to a soft yellow, nearly, but not quite bordering on a rose; over the quick to a dark purple or steel; recoat from one-sixth to one-tenth.
The above works slow, but with a good light and proper management it can be made to produce as good impression as any combination known, yet it is not so easily managed as No. 1.
