English Explanation of Mishnah Kelim
Earthen vessels and vessels of sodium carbonate are equal in respect of impurity: they contract and convey impurity through their air-space; they convey impurity through the outside but they do not become impure through their backs; and when broken they become clean. The rules regarding earthenware and sodium carbonate vessels are different. As I explained in the introduction, they can be made impure only by something entering their air space, even if the defiling agent does not touch them. They also convey impurity to food or other vessels that enter their air space, even if they do not come into contact with them. This is derived from Leviticus 11:33. They also convey impurity through their outsides. So if they are impure, and a piece of food touches the outside of the vessel, the food is impure. But if something impure touches the outside of the vessel (their backs) they are not defiled. Earthenware vessels cannot be made pure by entering a mikveh. The only way they can become pure is by being broken (see Leviticus 6:21, 11:33, 15:12).
