Mishnah 1א׳
כְּלֵי מַתָּכוֹת, פְּשׁוּטֵיהֶן וּמְקַבְּלֵיהֶן טְמֵאִין. נִשְׁבְּרוּ, טָהָרוּ. חָזַר וְעָשָׂה מֵהֶן כְּלִי, חָזְרוּ לְטֻמְאָתָן הַיְשָׁנָה. רַבָּן שִׁמְעוֹן בֶּן גַּמְלִיאֵל אוֹמֵר, לֹא לְכָל טֻמְאָה, אֶלָּא לְטֻמְאַת הַנָּפֶשׁ:
Metal vessels, whether they are simple or form a receptacle, are susceptible to impurity. If they break, they become clean. If they were re-made into vessels, they revert to their former impurity. Rabban Shimon ben Gamliel says: this does not apply to every form of impurity but only to that contracted from a corpse.
Mishnah 2ב׳
כָּל כְּלִי מַתָּכוֹת שֶׁיֶּשׁ לוֹ שֵׁם בִּפְנֵי עַצְמוֹ, טָמֵא, חוּץ מִן הַדֶּלֶת, וּמִן הַנֶּגֶר, וּמִן הַמַּנְעוּל, וְהַפּוֹתָה שֶׁתַּחַת הַצִּיר, וְהַצִּיר, וְהַקּוֹרָה, וְהַצִּנּוֹר, שֶׁנַּעֲשׂוּ לַקַּרְקָע:
Every metal vessel that has a name of its own is susceptible to impurity, except for a door, a bolt, a lock, a socket under a hinge, a hinge, a clapper, and the [threshold] groove under a door post, since these are intended to be attached to the ground.
