Keilim 8:8-9

Keilim 8:8

Let’s say that a sheretz (vermin) was found in a stove where the wood goes. If it’s from the outer edge inward, Rabbi Yehuda rules the stove unclean. The Sages say that if it’s from the inner edge outward, the stove remains ritually clean. Rabbi Yosi says that if it’s from opposite where the pot goes and inward, then the stove is unclean; from opposite where the pot goes and outward, clean. If a sheretz is lying in the place on an industrial boiler where a bathhouse attendant, a dyer or olive workers sit, the boiler remains ritually clean. It is only rendered unclean if the sheretz lies from the sealed portion inward.

Keilim 8:9

A cooking pit that has a place to hold pots is susceptible to ritual impurity. A glassblower’s pit is susceptible to impurity if it has a place to hold pots. A kiln used by those who work limestone, glass or pottery is not susceptible to impurity. If a baker’s oven has a rim, it is susceptible; Rabbi Yehuda says it’s susceptible if it has holes that serve as a stove, and Rabban Gamliel says it’s susceptible if it has rings on which to place pots.
