Scrape a little rotten-stone fine, and make into a paste with sweet oil. Rub on with a piece of flannel; let it dry, and polish with a chamois-skin. Copper is cleaned either with vinegar and salt mixed in equal parts, or with oxalic acid. The latter is a deadly poison, and must be treated accordingly.
WEIGHTS AND MEASURES.
As many families have no scales for weighing, a table of measures is given which can be used instead. Weighing is always best, but not always convenient. The cup used is the ordinary coffee or kitchen cup, holding half a pint. A set of tin measures, from a gill up to a quart, is very useful in all cooking operations.
One quart of sifted flour is one pound.
One pint of granulated sugar is one pound.
Two cups of butter packed are one pound.
Ten eggs are one pound.
Five cupfuls of sifted flour are one pound.
A wine-glassful is half a gill.
Eight even tablespoonfuls are a gill.
