Take of the best linseed oil one quart, to which add half a pint of the best spirits of turpentine, and a piece of lime about the size of a cricket-ball, broke in pieces; let it simmer on a stove or near the fire, covered over for two or three hours, then strain it through a coarse cloth and keep it for use.

It must be put on with a brush, and when it has lain on the work about twenty-four hours rub it off with a woollen cloth, and some oak saw-dust, and finish with a clean linen rag.

Another Oil To Heighten The Colour

Linseed oil one quart; litharge half an ounce; let them simmer together for an hour or two; then strain it off; take now about half-a-pint of spirits of turpentine, and put to it as much as you will of pounded turmeric, till a sufficiency of the colour is extracted: strain it off, and add it to the oil; it will be found excellent, as it heightens the colour of the wood, and is to be used the same as the foregoing.

N. B. - The process may be repeated two or three times, letting a day or two intervene; it will materially add to the beauty of the work.
