[Regarding] stewpots [placed] one within the other and their rims are even: [If] the sheretz is in the upper or lower [stewpot], it is tamei and the rest are tahor. [The pots] were [perforated] to the extent that liq- uid would enter: [If] the sheretz is in the upper [pot], all [the pots] are tamei. [If the sheretz was] in the lower [pot], it is tamei, but all [the other pots] are tahor. [If] the sheretz is in the upper [pot] and the lower [pot] extends [above it], it and the lower [pot] are tamei. [If the sheretz is] in the upper [pot] and the lower [pot] extends [above it], any [pot] that contains enough beverage to moisten is tamei.

[Regarding] metal utensils, their flatwares and their hollowares are tamei. [If] they break, they become tahor. [If] one refashioned them into utensils, they revert to their former state of tumah. Rabban Shimon ben Gamliel says: [This does] not [apply] to every [kind of] tumah, but [only] to corpse-tumah.

Every metal utensil that has a name of its own is tamei, except for a door, a door bolt, a lock, the socket that is under the pivot, the pivot, the beam, and a pipe, since these are made [to be attached] to the ground.

[Regarding] one who makes utensils from iron ore, or from a metal ingot, or from the hoop of a wheel, or from sheet metal, or from plating, from the bases of utensils, or from the rims of utensils, from the handles of utensils, from scraps, or from filings, [the utensils are] tahor. R’ Yochanan ben Nuri says: Even [utensils made] from cut pieces. [But utensils made] from pieces of broken utensils, [or] from fragments, or from nails that were known to have been made from [other] utensils, are tamei. [If one made utensils] from nails, Beis Shammai rule [them] tamei, but Beis Hillel rule [them] tahor.

[Regarding a piece of] tamei iron that one mixed with [a piece of] tahor iron, if the majority is from the tamei [source, the newly formed utensil] is tamei. And if the majority is from the tahor [source, the utensil] is tahor. [If it is] half and half, it is tamei. And the same applies [to a utensil made] from chalama and cattle dung. [A door bolt with] a knob is tamei. But [if it is] plated, it is tahor. A pin tumbler and a bolt are tamei. And [regarding] a [door bolt with a] knob, R’ Yehoshua says: [One may only] drag it from this door and hang it on another one on the Sabbath. R’ Tarfon says: It is like all [other] utensils, and may be carried within a courtyard.

A whorl [made] of metal, R’ Akiva rules it tamei, but the Sages rule it tahor. And a plated [whorl] is tahor. A spindle, a distaff, a rod, a symponia, and a flute, [if they are made] of metal, they are tamei. But [if they are] plated, they are tahor. [However,] if a symponia has a receptacle for [valves resembling] wings, it is tamei in either case.

A horn that is curved is tamei. But a straight [horn] is tahor. If its mouthpiece was of metal, it is tamei. [Regarding] its bell, R’ Tarfon rules it tamei, but the Sages rule it tahor.

A kidon, a spearhead, greaves, and a coat of mail are tamei. All women’s jewelry is tamei. A city of gold, chokers, earrings, and finger rings; a finger ring, whether it has a signet or it does not have a signet, [and] nose rings. [Regarding] a choker whose beads are of metal [and strung] on a linen or woolen thread, [even if] the thread snapped, the beads are tamei, since each one by itself is a utensil. [Regarding] a metal thread [that was strung] with beads of precious stones, pearls, or glass, if the beads broke and the thread alone remains intact, [the thread] is tamei. The remnant of a choker [is] the width of neck size of a young girl. R’ Eliezer says: [If] even one bead [remains], it is tamei, since [people] hang [it] around the neck.

[Regarding] an earring that is shaped like a pot at its lower end and like a lentil at its top, and [it] came apart, [the section] resembling a pot is tamei because [it is a] utensil with a receptacle, and the lentil-shaped [section] is tamei by itself. [However,] the hook is tahor. [An earring] that was made like a cluster [of grapes], and it came apart, is tahor.
