[Regarding] a sereedah that is placed on the mouth of an oven and sinks into it and it has no rim, [if] a sheretz is in [the sereedah], the oven is tamei. [If] a sheretz is in the oven, food that is in [the sereedah] is tamei. For only utensils protect from [the tumah of] an earthen- ware utensil. [Regarding] a barrel that is full of tahor beverages and is placed beneath the floor of an oven, [if] a sheretz is in the oven, the barrel and the beverage are tahor. [If the barrel] was inverted and its mouth [opened] to the airspace of the oven, [if] a sheretz is in the oven, beverage sufficient to moisten that is on the bottom of the barrel is tahor.

[R egarding] a pot that is placed in an oven, [if] a sheretz is in the oven, the pot is tahor, for an earthenware utensil does not render utensils tamei. If there was in [the pot] beverage sufficient to moisten, [the beverage] became tamei and transmitted tumah. Thus, this [pot] says: “That which made you tamei did not make me tamei, and [yet] you have made me tamei.”

[Regarding] a chicken that swallowed a sheretz and [then] fell into the airspace of an oven, [the oven] is tahor. But if [the chicken] died, [the oven] is tamei.

[Regarding] a leaven container [that is] surrounded by a sealed cover and placed into an oven, [if] leaven and a sheretz are in it and the dividing wall is between them, the oven is tamei, but the leaven is tahor.
