Iruiy Keli Rishon with Even Meluban:[1]

Iruiy Keli Rishon with Even Meluban refers to pouring a direct[2] stream of hot water from a Keli Rishon[3] onto an item [i.e. Iruiy Keli Rishon], and then passing a red-hot stone or red-hot metal [i.e. Even Meluban] throughout the entire[4] vessel, hence causing the water to boil.[5] Bedieved, even if the water was poured from a Keli Sheiyni it is valid if it had the Even Meluban pass through and boil the water in the entire vessel.[6] Vessels that have protruding areas that prevent passing the stone over them, are invalid for this form of Kashering.[7] The detailed laws of Hagala, which apply likewise to Iruiy Keli Rishon with Even Meluban, are explained in Halacha 10!

When is it required:[8] This form of Kashering is a valid alternative of Hagala for all vessels that require Hagala, but cannot have Hagala done to them, such as they are too large and thus cannot fit into a pot, or are immobile [such as a counter.] Nonetheless, in all cases that it is possible to perform Hagala within a Keli Rishon, then one must do so and may not rely on Iruiy Keli Rishon and Even Meluban.[9]



Practical ways of performing Iruiy Keli Rishon with Even meluban:

Using an iron: A hot iron which causes the water to boil may be used as an Even Meluban. Hence, when Kashering through Iruiy with Even Meluban one is to pour hot water onto the surface and then pass the hot iron throughout the entire surface of that item, hence causing the water to boil. When doing so, one must observe when the iron has lost its power of heat to be able to boil the water, and consequently reheat the iron to its boiling power, and continue from where he left off.

Using a water boiler “Kumkum”:[10] Water which is poured from an electric water boiler [“Kumkum”], while the heating coils are still on and the water is boiling, is considered like both Iruiy and Even Meluban, and hence when pouring from such a vessel there is no need to pass over the surface using a red-hot stone or metal. [This, however, can only be achieved while the boiler is still plugged in and attached to the heating element.]

Must the Even Meluban contact every part of the item being Kashered?

Yes.[11] However, some Poskim[12] rule that it suffices for the boiling water which hit the stone to spread to every area of the item, and it is not necessary that the actual stone contact all the areas. Thus, protrusions and the like which prevent placing the stone directly on them is only problematic if the water which hits the stone is unable to reach those areas. Whatever the case, using a water Kumkum while the water is still boiling with the heating element still on, can read all areas of the vessel, and be valid according to all.

[2] Admur 451:29-30; This refers to “Lo Nifsak Hakiluach” in its Hebrew term and means that the water was still attached to the Keli Rishon pot by the time it hit the surface of the vessel. See next footnote for the full details of this requirement.

[3] It is disputed amongst Poskim as to whether one must pour from a Keli Rishon when using Even Meluban, as in any event the stone will re-boil the water, and hence should be valid even if the water is poured from a Keli Sheiyni or Nifsak Hakiluach. Practically, while the custom is to be lenient, initially it is proper to be stringent in all this. [Admur 451:30]

[5] Admur 451:27; See Q&A!

[6] Admur 451:30

[7] Admur 451:27

Other opinions: Some Poskim invalidate the use of Iruiy Keli Rishon with Even Meluban as an alternative for Hagala. [See M”B 451:51]

[8] Admur 451:27

[9] The reason: As some Poskim rule Iruiy with Even Meluban is not a valid alternative to Hagala. [Admur ibid]

[10] See Sefer Hakashrus [1 footnote 22] who compares this form of Kashering to Iruiy with Even Meluban. So also seems logical being that the coils inside the boiler are constantly boiling the water which is coming into contact with the item. It is hence just like placing an Even Meluban over the water, as the entire point of the Even Meluban is to heat it to the point of a Keli Rishon. [See Admur 451:27 and 30 that the entire purpose of the Even Meluban is to boil the water, and hence what difference does it make if it boils it from close or from far.]
