426. To cleanse Vials and Pie Plates.
Bottles and vials that have had medicine in them, may be cleansed by putting ashes in each one, and immersing them in a pot of cold water, then heating the water gradually, until it boils. When they have boiled in it an hour, take it from the fire, and let them remain in it till cold; then wash them in soap-suds, and rinse them in fair water till clear. Pie plates that have been used much for baking, are apt to impart an unpleasant taste to the pies, which is owing to the lard and butter of the crust soaking into them, and becoming rancid. It may be removed by putting them in a brass kettle, with ashes and cool water, and boiling them in it an hour.
Earthen-ware that is used to bake in, will be less liable to crack from the heat if put, before they are used, into a vessel, with sufficient cold water to cover them, then heated in it gradually, till the water boils. When the vessel is taken from the fire, the ware should remain in until cold.
428. To temper New Ovens and Iron-ware.
New ovens, before they are baked in, should have a fire kept up in them half a day. As soon as the wood is removed, put up the lid of the oven. It should not be used for baking until it has been heated the second time. If not treated in this manner, it will never retain the heat well. New flat irons should be heated half a day before they are used, in order to retain heat well. Iron cooking utensils, when new, will be less liable to crack if heated gradually five or six hours, and then cooled slowly, before being used to cook in. Cold water should never be turned into hot iron utensils, as it will crack them by cooling the surface too suddenly.
429. To polish Brass, Britannia, and Silver Utensils.
Rotten stone, mixed with a little spirit, is the best thing to clean brass with: rotten stone and oil does very well. They should be polished with dry rotten stone, and a dry cloth. Hot vinegar and milk makes brass look nice—it should be rinsed off, wiped dry, and rubbed over with chalk, to kill the acid, and give the brass a polish. Brass looks very nice cleaned in this manner, and will keep clean a long time, provided all the acid is killed—if not, they will turn very soon. When brass utensils are not in use, they should be thoroughly cleaned with rotten stone and oil, and wrapped up tight to exclude the air. Whiting or chalk is good to polish silver. If the silver is spotted, wet the chalk, (which should be powdered,) rub it on the silver, and let it remain until dry; then rub it off with a clean dry cloth. When chalk will not remove spots, hot ashes will. Britannia-ware should be rubbed with a flannel rag dipped in sweet or linseed oil, if spotted, then washed in soap-suds, and wiped dry. To give it a polish, rub it over with dry powdered chalk or whiting, using a clean dry rag.
