#A Kli Sheni is a vessel into which a hot liquid or solid was poured.<ref>39 Melachos (vol 2 pg 577). The Mishna on Shabbos 42a states that while one may not place spices into a ''Kli Rishon'', there is no prohibition of doing so into a ''Kli Sheini''. The Gemarah on Shabbos 40b relates that when the Amora Rav Avdimai wished to heat up his flask of oil, he was advised to place it into a ''Kli Sheini'' in order to avoid the problem of ''Bishul.'' The Gemara explains that this heter is based on the assumption that a ''Kli Sheini'' does not have the ability to fully cook an item placed inside of it. There is a discussion among the Rishonim as to the exact reason for this ''heter''. | #A Kli Sheni is a vessel into which a hot liquid or solid was poured.<ref>39 Melachos (vol 2 pg 577).

*Tosfos on 40b writes that since a ''Kli Rishon'' was originally placed directly on top of the fire, its wall will remain heated for an extended period of time. However, since a ''Kli Sheini'' was never positioned on top of the flame, its wall will not retain this same level of heat and will cool off at a much quicker pace. According to this logic, the ''heter ''of a ''Kli Sheini'' would apply even if the contents inside the ''Kli'' are still at a level of ''yad soledes bo ''because the walls of the vessel are already in the process of cooling down.</ref> | *Tosfos on 40b writes that since a ''Kli Rishon'' was originally placed directly on top of the fire, its wall will remain heated for an extended period of time.

*Or Same'ach Shabbat 9:2 explains that kli sheni is completely removed from the possibility of cooking since it is a second derivative of the heat of the fire, similar to ''koach kocho''. See there where he goes so far as to suggest that the concept that ''kalei habishul'' cook in a kli sheni is only rabbinic. Shoel Umeishiv 5:11 has a similar approach, while Shevet Halevi 7:101:2 and Shulchan Shlomo 318:11:2 cited by Torat Melachot v. 2 p. 134 disagree with the approach of the Or Same'ach.</ref> | |||
#There is disagreement amongst the poskim as to which types of food fall into the category of Kalei Bishul, foods for which it is forbidden to pour from kli sheni onto them.<ref>*The Mishna on Shabbos 145b explains that, although it is forbidden to place uncooked foods into a Kli Rishon on Shabbos, one would be permitted to pour hot water onto these foods from a Kli Sheini. Rashi explains that this act of pouring is not considered Bishul and would therefore be permissible even if done on Shabbos itself. * However, the Mishna goes on to explain that there are certain types of fish for which even pouring would be considered a legitimate act of Bishul as they are more “easily cooked” and therefore considered to be within the category of Kalei Bishul. Since the Mishna writes that even pouring from a Kli Sheini would be assur, we can derive that placing these types of foods directly into a Kli Shinei would be forbidden as well. * There is a disagreement amongst the poskim as to which types of foods fall into this category of Kalei Bishul. The Mishna Brurah (Be’ur Halacha Siman 318 S”K 4) writes that any food which the Gemarah does not explicitly leave out of the category of Kalei Bishul would be forbidden to be placed into a Kli Sheini. However, the Chazon Ish (Siman 52 S”K 19) limits the category of Kalei Bishul. He explains that the only additional items which would be considered Kalei Bishul are those which appear to be easily cooked</ref> | #There is disagreement amongst the poskim as to which types of food fall into the category of Kalei Bishul, foods for which it is forbidden to pour from kli sheni onto them.<ref>*The Mishna on Shabbos 145b explains that, although it is forbidden to place uncooked foods into a Kli Rishon on Shabbos, one would be permitted to pour hot water onto these foods from a Kli Sheini.
