Keilim 22:10-23:1

Keilim 22:10

A toilet seat is susceptible to both midras and corpse impurity. If it comes apart, the leather cover remains susceptible to midras but the iron interior is only susceptible to corpse impurity. A folding chair upholstered with leather is susceptible to both midras and corpse impurity. If it came apart, the leather is subject to midras while the chair part is insusceptible to impurity. A bathhouse bench that has two wooden legs is susceptible to impurity; if one leg is wood and the other is stone, it is insusceptible. If bathhouse floorboards were professionally joined, Rabbi Akiva says they’re susceptible to midras (because people sit on them) but the Sages declare them insusceptible because they’re only made for water to flow beneath. A fumigating cage that has a receptacle for garments is susceptible to impurity but one made like a beehive (i.e., without such a receptacle) is insusceptible.

Keilim 23:1

If a (ritually unclean) ball, mold for shoes, amulet or tefillin was torn, then one who touches them is rendered unclean but if one touches what’s inside them, he remains clean. If a (ritually unclean) saddle is torn, one who touches its stuffing is rendered unclean because the stitching connects the stuffing to the exterior.
