Brown earthen pans are said to be best for milk and for cooking. Tin pans are lighter, and more convenient, but are too cold for many purposes. Tall earthen jars, with covers, are good to hold butter, salt, lard, etc. Acids should never be put into the red earthen ware, as there is a poisonous ingredient in the glazing which the acid takes off. Stone ware is better and stronger, and safer every way than any other kind.
