1. We mentioned that Hillel and Shammai argued in 3 places, so the gemara explores them. The amount of dough obligated in tithing challah for the Kohen. Shammai says one kav. Hillel says two kav. The Halacha is compromise view of 1 and a half kav. This is equal to the amount of manna each Jew are a day in the desert. Second dispute is about amount of drawn water invalidates a mikveh. Third dispute is when a woman gets her period if she is considered retroactively tamei or not.

2. The law that land outside of Israel is tamei was first instituted by the zugos, in the beginning of the 2nd temple. The original decree was on the soil itself and only to suspend Terumah it touched, not to burn it. The Rabbis 80 years before the destruction of the Temple added that Terumah should be suspended if it was above airspace of land outside Israel. In Usha, post the destruction they added to burn Terumah that came in contact with the soil.

3. A brief intro- Earthenware can accept tumah and cannot be purified in a mikveh. Only hollow vessels accept this tumah. If it brakes, it loses tumah and does not regain tumah it it rebuilt. Earthenware contracts tumah from inside, not outside. Metal contracts tumah even if it is flat. It can be purified in a mikveh. It contracts tumah with contact.

Glass is not mentioned in the Torah as a material that accepts tumah. However, the rabbis added glass to list of vessels that contract tumah. This is because glass is from the sand, which resembles earthenware that comes from the ground. It should follow that glass cannot be purified in a mikveh bc it’s like earthenware, but if a glass vessel had a lead patch to plug a hole, it could have purification in a mikveh bc r Meir says we go after the “mamid “- the material holding the kli together.
