Take three ounces of pearl-ash, and put it into a clean black bottle with a pint and a half (not more) of soft water. The proportion is an ounce of pearl-ash to half a pint of water. Cork it very tightly, shake it, and it will be fit for use as soon as all the pearl-ash is dissolved. A table-spoonful of this liquid is equal to a small tea-spoonful of pearl-ash in the lump or powder. Keeping it ready dissolved will be found very convenient.
