Or, to make Glass Jars look like China.
After painting the figures, cut them out, so that none of the white of the paper remains, then take some thick gum Arabic water, pass it over all the figures, and place them on the inside of the glass to taste; let them stand to dry for 24 hours, then clean them well with a wet cloth betwixt the prints, and let them stand a few hours longer lest the water should move any of the edges, then take white wax and flake white, ground very fine, and melt them together; with a japanning-brush go over all the glass above the prints; done in this manner they will hold water; or, boil isinglass to a strong jelly, and mix it up with white lead, ground fine, and lay it on in the same manner; or use nut-oil and flake-white. For a blue ground, do it with white wax and Prussian blue, ground fine; for red, wax and vermilion, or carmine; for green, wax and verdigris; for a chocolate color, wax and burnt umber.
To make Grindstones without Moulds.
Take of river sand, 3 parts; of seed-lac, washed, 1 part. Mix them over a fire in a pot, and form the mass into the shape of a grindstone, having a square hole in the centre; fix it on an axis with liquefied lac, heat the stone moderately, and by turning the axis it may easily be formed into an exact circular shape. Polishing grindstones are made only of such sand as will pass easily through fine muslin in the proportion of 2 parts of sand to 1 of lac. This sand is found at Ragimaul. It is dering the dwellings of the poor clean and whole-composed of small angular crystalline particles some.
First. For rough outside walls - those exposed to the weather-the best mixture is clear lime and water. Any animal or vegetable substance added diminishes the adhesion and durability of the wash.
Second. But if the wall is hard and smooth, the tinged red with iron; 2 parts to 1 of black magnetic sand. The stone-cutters, instead of sand, use the powder of a very hard granite called corune. These grindstones cut very fast. When they want to increase their power they throw sand upon them, or let them occasionally touch the edge of a vitri
