1315. Coloring for Cheese.—The coloring for cheese is, or at least should be, Spanish arnotto; but as soon as coloring became general in this country, a color of an adulterated kind was exposed for sale in almost every shop; the weight of a guinea and a half of real Spanish arnotto is sufficient for a cheese of fifty pounds' weight. If a considerable part of the cream of the night's milk be taken for butter, more coloring will be requisite. The leaner the cheese is, the more coloring it requires. The manner of using arnotto is to tie up, in a linen rag, the quantity deemed sufficient, and put it into half a pint of warm water over night. This infusion is put into the tub of milk, in the morning, with the rennet infusion; dipping the rag into the milk, and rubbing it against the palm of the hand as long as any color runs out.
1316. To make Cement for Bottles or Preserve Jars.—Take one-third bees'-wax and two-thirds rosin, according to the quantity of cement required. Pound the rosin fine, and put it with the wax to melt in any old vessel fit for the purpose. When it is melted, take it off the fire, and add powdered brick-dust till it is as thick as melted sealing-wax. Then dip the bottle necks into the cement, and in a few minutes the mixture will be dry.
1317. Blue Wash for Walls.—Take one pound of lump blue vitriol; pound it in a stone mortar as fine as possible; dissolve it in a quart or two of hot water. Slake about a quarter of a peck, or perhaps a little more of lime, and when cold pour in the blue water by degrees, and make it whatever shade you desire.
The lime must be slaked and the vitriol dissolved in earthen or stone ware, and the whole mixture stirred with a metal spoon. If wood is used for any of the above purposes, the color will be changed. A new brush should also be used to put it on the walls, and they must first have a coat or two of whitewash, to destroy all smoke and other impurities.
1318. Yellow Wash for Walls.—One quarter of a pound of chrome yellow, one quarter of a pound of gum senegal, two pounds of whiting.
