Immersing Dishes in the Mikvah

(22) Gold and silver, copper, iron, tin, and lead— (23) any article that can withstand fire—these you shall pass through fire and they shall be clean, except that they must be cleansed with water of lustration; and anything that cannot withstand fire you must pass through water.

GEMARA: The Sages taught: And they all require immersion in forty se’a of water, including utensils that must first be purged in boiling water or heated until white-hot. The Gemara asks: From where is this matter derived? Rava says: It is derived from that which the verse states with regard to utensils captured in the battle against the Midianites: “Anything that may tolerate the fire, you shall make to go through the fire, and it shall be pure” (Numbers 31:23). By stating: “And it shall be pure,” the verse added to the process another required act of purification in addition to heating the utensil with fire, which is understood to be immersion.

(1) ...One who acquires from an idol worshipper a meal vessel of metal or glass or vessels or covered in lead from the inside - even though they are new one must dunk them in a mikvah or a stream that is forty se'ot. GLOSS: There are those who says that vessels that are covered in lead even on the inside are dunked in a mikvah without a blessing, and this is how we act.

(2) The vessel must be loose in your hands at the time of dunking, for if it is tight in your hands it is an interposition, and if you dampen your hand in the water at the outset there is no need to worry (GLOSS: and specifically that you dampened your hands in the waters of the Mikvah but not in water that is detached).

(3) Bless "on the dipping of a vessel", and if there are two or more bless "on the dipping of vessels".
