Keilim 2:5-6

Keilim 2:5

The covers of jugs for wine and oil, as well as those of barrels from Nayar, are not susceptible to ritual impurity unless one modifies them for use as containers. The cover of a saucepan is not susceptible to ritual impurity when it is perforated or has a pointed protrusion; if it lacks either of these features, then it is susceptible to ritual impurity because one also uses it to strain vegetables. Rabbi Eliezer ben Tzadok says the reason is because one presses stewed vegetables on it.

Keilim 2:6

Let’s say that broken pottery was found in a kiln. If the vessel broke before it was completed, it is not susceptible to ritual impurity; if after, then it is. Rabbi Eliezer bar Tzadok says that an earthenware water sprinkler is susceptible to ritual impurity; Rabbi Yosi says that it isn’t because the water comes out in drops.
