A cup, the majority of [whose circumference] chipped away, is tahor. If it became chipped [with] three [chips] around the majority [of its circumference], it is [also] tahor. R’ Shimon says: If [the cup] leaks a majority of its water, it is tahor. If [the cup] developed a hole, and one repaired it whether with tin [or] with pitch, it is tahor. R’ Yose says: [If he plugs it] with tin, it is tamei. But [if] with pitch, it is tahor.
