Rabbi Baruch Bodenheim: Gemara Shabbos: Perek Kirah, יום שני, Cheshvan 12, Daf 42a Sugya – Kli Sheini (11/03/25)

I was so excited to receive a summary yesterday of the Sugya we are completing by Dr. Cohen. 

Please write a summary of 

• The argument between Bais Hillel and Bais Shammai. 

• The different reasons (Rashi, Tosfos, Ran) why it is permitted to pour hot water from a Kli Rishon into a cup of cold water. 

• The different explanations (Rashi, Tosfos, Ran, Rashba) whether אמבטיה is a Kli Rishon or Kli Sheini and why it is forbidden according to everyone to pour cold water into a hot אמבטיה.

• List a stringency and leniency according to the Ran and according to the Tosfos.

Do we conclude lhalacha like Bais Hillel or like ר’ שמעון בן מנסיא?
