Metal utensils contract tumah and become tahor [when] broken; [these are] the words of R’ Eliezer. R’ Yehoshua says: They only become tahor [when] intact. How so? [If] one sprinkled upon [the metal utensils], [and] they broke on that same day, [and] he refashioned them and then sprinkled upon them a second time that day, they are tahor; [these are] the words of R’ Eliezer. R’ Yehoshua says: No sprinkling [may be done] before the third and seventh [day].

An ‘‘arkuvah’’ key that broke at its bend is tahor. R’ Yehudah rules [it] tamei, because one can unlock [the door] with it from the inside. And a ‘‘gamma’’ key that broke at [the bend of] its gamma is tahor. If it had teeth and holes, it is tamei. [If the] teeth were removed, it is tamei on account of [the] holes. [If the] holes were sealed, it is tamei on account of [the] teeth. [If the] teeth were removed and [the] holes were sealed, or they broke into each other, it is tahor. A mustard strainer in which three [of its] holes at the bottom broke into one another is tahor. And a grinding funnel of metal is tamei.

Wooden utensils, leather utensils, bone utensils, [and] glass utensils: Their flatwares are tahor but their hollowares are tamei. If they break, they become tahor. [If] one remade [the broken utensils] into [new] utensils, they are susceptible to tumah from then on. [Regarding] a bin, a chest, a cabinet, a straw basket, a reed basket, and the cistern of an Alexandrian ship, that have [flat] bottoms, and they [can] contain forty liquid se’ahs, which are two kors of dry [measure], these [utensils] are tahor. All other utensils, whether they can contain [forty liquid se’ahs], or whether they cannot contain [forty liquid se’ahs], are tamei; [these are] the words of R’ Meir. R’ Yehudah says: A wagon’s barrel, provision chests of kings, a tanners’ trough, the cistern of a small ship, and a coffin, even though they [can] contain [forty liquid se’ahs], are [all] tamei, because they are designed for no other purpose than to be moved together with their contents. But [as regards] all other utensils, those that can contain [forty liquid se’ahs] are tahor, while those that cannot contain [forty liquid se’ahs] are tamei. There is no [difference] between the words of R’ Meir and the words of R’ Yehudah, except a kneading trough of a householder.

Baking boards of bakers are tamei. [But those] of householders are tahor. If he painted them with red paint or painted them with saffron [dye], they are tamei. [Regarding] a baker’s shelf that was fixed onto a wall, R’ Eliezer rules it tahor, but the Sages rule it tamei. A utility plate of bakers is tamei, but [the plate] of householders is tahor. If one made a rim on its four sides, it is tamei. If it [subsequently] becomes broken open on one side, it is tahor. R’ Shimon says: If one prepared it so that he may slice [dough] upon it, it is tamei. Similarly, the rolling pin is tamei.
