# A pot that absorbed something through liquids can be koshered<ref>Does hagalah remove all of the beliyot? Hagalat Kelim p. 27 quotes many who say that hagalah removes all of the beliyot including: Piksei Rabbenu Yechiel Mparis 42, Kol Bo Hagalah, Pri Megadim M”Z 452:4, E”A 467:13. However, the Shoel Umeishiv 6:41 s.v. vheneh questions this and prefers that hagalah removes most of the beliyot and the rest is batel and that’s why it is ineffective on pesach. [This would correspond to the Rashba (cited in Shulchan Aruch YD 99:7) as to why one can use a pot initially after hagalah if that involves nullification.] | # A pot that absorbed something through liquids can be koshered<ref>Does hagalah remove all of the beliyot?

</ref> of that absorption with boiling<ref>Does hagalah need to be 212? Hagalat Kelim by Rabbi Tzvi Cohen 10:19 writes that if someone is using steam to do hagalah the water needs to reach 212 degrees fahrenheit for hagalah. Mesoret Moshe v. 3 p. 128 quotes Rav Moshe as holding that essentially if one knew that a machine was only used for a certain temperature and not more it can be koshered with heating water in it at that temperature. Only initially do we try to actually boil water even if it wasn't used that way (Rama 451:6) otherwise the rule is kbolo kach polto for hagalah (Raah cited by Shach 121:17). | </ref> of that absorption with boiling<ref>Does hagalah need to be 212?

# Rabbenu Tam: Immediately when the kli is placed in the boiling water it will give off its taste and reabsorb taste from the water. Hagalat Kelim p. 27 cites that this is the opinion of Tosfot Avoda Zara 76a s.v. mkan, Tosfot Chullin 100b s.v. bshekadam, 108b s.v. shnafal, Smag lavin 78, Rosh end of a”z, pesachim 2:7, Sefer Hatrumah 55, Rashba Chullin 108b, Torat Habayit 4:4, respona 1:262, Ran Chullin end of perek 8, Ritva Chullin 108b quoting Rabbenu Tam, Tur and Rama 452:1. | # Rabbenu Tam: Immediately when the kli is placed in the boiling water it will give off its taste and reabsorb taste from the water.

# Rashbam: First the kli absorbs new taste and only afterwards it starts to give off its taste. Accordingly you would have to wait some time for hagalah to be effective. It isn’t clear how long that is. This is the opinion of Rashbam cited by Tosfot Chullin 108b s.v. shnafal. | # Rashbam: First the kli absorbs new taste and only afterwards it starts to give off its taste.
