1color desired is to approach more or less closely to yellow, or is to assume more of a reddish tint.
3When time is an object, there is a way of making the ingredients in question dissolve more quickly, by placing the bottle containing them, loosely corked, on a warm stove, taking care to insert between bottle and stove a fourfold thickness of paper, in order to prevent the bottle from bursting in consequence of too great a development of heat.
5Orange Yellow.—Place 7/8 of a quart of spirits of wine, 2 ounces of arnotto and 1/3 of an ounce of potash in a bottle, and let them steep for three days, stirring the mixture at frequent intervals. After having allowed it to stand for three days more, that portion of the liquid which has clarified should be poured, with the greatest precaution, into another bottle, in order to be mixed with the varnish later.
7Ordinary Solid Varnish
9This varnish, like all the varnishes of the same kind which we are about to describe, might almost be said to make itself, since all that is necessary is to leave its component materials in a well-corked bottle. However, since it is well to know how any piece of work may be done quickly and well, we will indicate the process of fusion by means of a water bath which may be used for all the alcohol varnishes.
11This process consists in enclosing in a bottle all the ingredients required to make a varnish.
131. The bottle in question should be at least a third larger than necessary to hold the matter contained in it.
152. The bottle should be corked with a paper cover, and one must not forget to perforate this paper cover with a needle or pin, in order to supply a vent for the air in the interior of the bottle, which, if the vent did not exist, might burst.
17Once these precautions have been observed, one takes a vessel of any kind, a casserole, for instance, either made of earthenware or of tin, and places a strip of wood or some straw or sawdust at the bottom. The bottle is then placed in the casserole, or whichever one of the substances mentioned that may have been selected, in order that its bottom will not touch the bottom of the casserole itself, a contact which might result in the bursting of the glass. This done, water is poured into the casserole, care being taken that the water remains .117 inches below the liquid enclosed in the bottle. The casserole may then be placed on a coal fire which should be regulated in such manner that the bottle does not boil up too strongly. From time to time the bottle may be taken out of the water in order to see whether the ingredients it contains have entirely dissolved. When no undiscovered particles are to be seen, and the contents of the bottle have become completely merged, the casserole may be withdrawn from the fire, which then may be banked.
