An oven which they partitioned with boards or hangings, and in it was found a sheretz in one compartment, the entire oven is unclean. A hive which was broken and its gap was stopped up with straw and was suspended within the air-space of an oven while a sheretz was within it, the oven becomes unclean. If a sheretz was within the oven, any food within the hive becomes unclean. But Rabbi Eliezer says that it is clean. Rabbi Eliezer said: if it affords protection in the case of a corpse which is more consequential, should it not afford protection in the case of an earthenware vessel which is less consequential? They said to him: if it affords protection in the case of corpse impurity, this is because tents are divided, should it also afford protection in the case of an earthenware vessel which is not divided?

If the hive was complete, and so too in the case of a basket or a skin-bottle, and a sheretz was within it the oven remains clean. If the sheretz was in the oven, any food in the hive remain clean. If a hole was made in it: A vessel that is used for food must have a hole large enough for olives to fall through, If it is used for liquids the hole must be large enough for liquids to pass into it, And if it is used for either it is subjected to the greater restriction: the hole need only be large enough for liquids to pass into it.

Netting placed over the mouth of an oven and slightly sinking into it, and having no frame: If a sheretz was in it, the oven becomes unclean; If the sheretz was in the oven, the food in the netting becomes unclean, since only vessels afford protection against an impurity in an earthen vessel. A jar full of pure liquids placed beneath the bottom of an oven, and a sheretz in the oven – the jar and the liquids remain clean. If it was inverted, with its mouth projecting into the air-space of the oven, and a sheretz was in the oven, the liquid that clings to the sides of the jar remains clean.

A pot which was placed in an oven if a sheretz was in the oven, the pot remains clean since an earthen vessel does not impart impurity to vessels. If it contained dripping liquid, the latter contracts impurity and the pot also becomes unclean. It is as if this one says, "That which made you unclean did not make me unclean, but you have made me unclean."

If a rooster that swallowed a sheretz fell within the air-space of an oven, the oven remains clean; If the rooster died, the oven becomes unclean. If a sheretz was found in an oven, any bread in it contracts second degree impurity since the oven is of the first degree.

A leavening pot with a tightly fitting lid which was put in an oven, and there was some leaven and a sheretz within the pot, but there was a partition (of inedible bread) between them, the oven is unclean but the leaven is clean. But if it was an olive's bulk of corpse, both the oven and the house are unclean, and the leaven remains clean. If in the partition there was an opening of one handbreadth, all become unclean.

A sheretz which was found in the eye-hole of an oven or of a double stove or of a single stove: If it was outside the inner edge, it is clean. If it [the oven] was in the open air, even if it was an olive's bulk of corpse it is clean. If there was [in the eye-hole] an opening of one handbreadth, it is all unclean.

If a sheretz was found in the [place in a stove] where wood is put: Rabbi Judah says: if it was within the outer edge, [the stove] becomes unclean. But the sages say: if it was outside the inner edge [the stove] remains clean. Rabbi Yose says: if it was found beneath the spot where the pot is placed and inwards, the stove becomes unclean, but if beneath the spot where the pot is set and outwards, it remains clean. If it was found on the place where the bath-keeper sits, or where the dyer sits, or where the olive-boilers sit, the stove remains clean. It only becomes unclean only [when the sheretz] is found in the enclosed part and inwards.

A pit which has a place on which a pot may be set is unclean. And so also an oven of glass-blowers, if it has a place on which a pot may be set, it is unclean. The furnace of lime-burners, or of glaziers, or of potters is clean. A purna: If it has a frame is unclean. Rabbi Judah says: if it has coverings [for compartments.] Rabban Gamaliel says: if it has edges.

If a person who came in contact with one who has contracted corpse impurity had (food liquids in his mouth and he put his head into the air-space of an oven that was clean, they cause the oven to be unclean. If a person who was clean had food or liquids in his mouth and he put his head into the air-space of an oven that was unclean, they become unclean. If a person was eating a pressed fig with impure hands and he put his hand into his mouth to remove a small stone: Rabbi Meir considers the fig to be unclean But Rabbi Judah says it as clean. Rabbi Yose says: if he turned it over [in his mouth] the fig is unclean but if he did not turn it over the fig is clean. If the person had a pondion in his mouth, Rabbi Yose says: if he kept it there to relieve his thirst it becomes unclean.

If milk [of an impure woman] dripped from a woman's breasts and fell into the air-space of an oven, the oven becomes unclean, since a liquid conveys impurity regardless of whether one wanted it there or not. If she was sweeping it out and a thorn pricked her and she bled, or if she burnt herself and put her finger into her mouth, the oven becomes unclean.
