The handles of a large earthenware container, the bulges at the bottom of such a container, and the back of its walls do not protect their contents when sealed close in a tent where a corpse is located. If one cut them off, planed them, and made them into containers, they protect their contents if sealed close. The rationale is that the concept of sealing something close applies only to containers.
When clay is put into an earthenware container and filled half of it, it does not nullify it from being considered as a container. If keilim are sunk in that clay and the container is sealed close, the contents are protected from impurity.
🏺 Earthenware Limits
By Torah law, a sealed container protects ALL its contents (food, liquids, garments, all vessels). By Rabbinic decree, a sealed earthenware container only protects food, liquids, and other earthenware — NOT garments or immersible vessels (kelei shetef). The reason: earthenware can become impure and an impure vessel cannot intervene. Common people's earthenware is assumed impure, so extending protection to immersible vessels inside would mislead. A person sealed inside an earthenware container remains pure — too unusual to decree against.

Special Pure Earthenware: Red Heifer and Sacred Foods
An earthenware container protects its contents from impurity when sealed close unless it is perforated with a hole large enough for a pomegranate to fall through. If it is large, the majority of it must be damaged and open for it to be disqualified. What is implied? If there was a large container and half was damaged, it was sealed close, including the damaged portion, it protects its contents from impurity even though it is not considered a utensil with regard to impurity. If, however, a container that was sealed close had a hole or a crack and the hole was not closed, it becomes impure and does not protect its contents. How large must the hole be to disqualify the container? If the container was used for foods, the measure is a hole large enough for olives to fall through. If it was used for liquids, its measure is that the hole must be large enough to enable liquids to seep in when the container is placed in them. If it is used for both these purposes, we rule stringently and if a hole was made that was large enough for liquids to seep in, it does not protect its contents until the hole is closed or reduced in size.
🔴 Red Heifer Vessels
Earthenware vessels used for the ashes of the red heifer or for sacred/sacrificial foods: even common people's word is trusted for their purity (since they are careful with these). Therefore such earthenware, when sealed, protects everything inside — including immersible vessels.

Earthenware Plate Over Skylight and Complex Loft Cases
The following rules apply when there was an oven in an ohel where a corpse was located. The oven had a covering upon it, it was sealed close, but it was cracked. If the crack was as wide as the opening of the rod of a plow which is a handbreadth in circumference, the oven is impure even though the rod could not be inserted into the oven through the hole, but the hole was equal to its size. If the hole was smaller than this, the oven is pure. If the covering was cracked to the extent that the rod of a plow could enter, it is impure. If it is less, it protects its contents with a sealed covering. If the crack is round, we do not consider it as if it was long. Instead, the measure is dependent on whether the opening of the rod of a plow could be inserted.
🏠 Loft Protection
An earthenware dish over a skylight (between house and loft): if intact, protects food/liquids/earthenware in the loft. A person and immersible vessels in the loft are impure by Rabbinic decree. A metal container in the loft filled with liquids: the container is impure (7 days) but the liquid inside is pure. A woman kneading in a wooden trough: she and the trough are impure; dough is pure while she is kneading — if she stops and returns to touch it, the dough becomes impure.

🎓 Key Principles
Chapter 22
⚖️
Torah vs. Rabbinic Scope of Sealed Earthenware Torah law gives full protection to all sealed containers; Rabbinic law restricts earthenware to only protect foods, liquids, and other earthenware — based on the presumption that common people's earthenware is impure.
🔴
Red Heifer Context Overrides the Decree When earthenware is used for the red heifer or sacred items, universal trustworthiness regarding its purity means the Rabbinic restriction does not apply — it protects everything.
💧
Active Contact vs. Passive Contact Food/liquid in an impure vessel remains pure while being actively kneaded/worked (the work keeps it separate) — only when the person stops and touches again does the impurity transfer.
🧑
A Person in a Sealed Earthenware Container Remains Pure The Rabbinic restriction on earthenware protecting immersible vessels was not extended to include a person — too uncommon a situation to require a decree.
