There is an opening between the lower story and the upper story of a house that has been covered by a pot. [The pot has] a crack large enough for liquid to seep in. Beis Shammai say: Everything [in the house] becomes tamei. Beis Hillel say: The pot becomes tamei, but the upper story remains tahor. R’ Akiva says: Even the pot re-mains tahor.

[If the pot] is whole, Beis Hillel say: It protects everything [from becoming tamei]. However, Beis Shammai say: It protects only food, liquids, and earthenware. Beis Hillel subsequently ruled like Beis Shammai.

[If] there is a bottle [in the upper story] full of tahor liquid, the bottle becomes tamei for seven days, [even though] the liquid remains tahor. However, if one pours [the liquid] into a different vessel, it becomes tamei. [If] a woman is kneading [dough] in a bowl, the woman and the bowl become tamei for seven days, but the dough remains tahor. However, if [the dough] is trans-ferred to a different vessel, it becomes tamei. Beis Hillel subsequently ruled like Beis Shammai.

[If] the utensils are made of dung, stone, or [unbaked] clay, everything remains ta-hor. [If] the utensil is [considered] tahor for use with sanctified [food] or the parah adumah procedure, everything remains tahor, because everyone is trustworthy re-garding the parah adumah procedure. [The reason for the above rulings is] because utensils that are always tahor, and also tahor earthenware utensils, curtail [tumah when combined] with the walls of a structure.
