Comentário sobre Kelim 3:3

חבת שניקבה – when it releases olive [oil]. And it is pure, and when it was repaired with pitch, it becomes susceptible to receive defilement from here onwards.

A jar that had a hole and was mended with pitch and then was broken again: If the fragment that was mended with the pitch can hold a quarter of a log it is unclean, since the designation of a vessel has never ceased to be applied to it. A jar had a hole in it and thereby became pure, as we learned in mishnah two. When someone fixed it, it again became susceptible to impurity. Then it was broken yet again, leaving a fragment that had been fixed with the pitch. As long as this fragment can still hold a quarter of a log, it is susceptible to impurity. The reason is that although the jar broke, it is still considered a vessel, and when it was fixed it could receive impurity again. Therefore broken pieces of it that can hold a quarter of a log are susceptible to impurity.

חזרה ונשברה – into many pieces. That shard which has in it pitch holding one-quarter [of a LOG] and it sits without being supported/propped up is impure. But are dealing with a jar that holds from a LOG to a SEAH [the uncleanness will persist if the remnant will hold] a quarter of a LOG as is taught in the Mishnah in the previous Chapter (Tractate Kelim, Chapter 2, Mishnah 2). But even though the closing up (through repair with pitch) has no effect on the hole that comes after breakage, this closing up is different because it was done prior to having nullifying the designation of a vessel from it, for a jug that was perforated, its designation as a jug is upon it even though it is pure, but earthenware that departs from the jug, nullifies the designation of the name of a vessel from it even though it is not perforated. Therefore, closing up its hole has no benefit.

A potsherd that had a hole and was mended with pitch, it is clean though it can contain a quarter of a log, because the designation of a vessel has ceased to be applied to it. In contrast, a potsherd that had a hole in it and was then fixed, cannot become impure because a potsherd is not a vessel, even if it can contain a quarter of a log. The rule in this matter is as follows: if a broken piece of earthenware gets a hole in it, it can never become impure again because even if it is fixed, it is not considered a vessel.
