כְּלֵי עֵץ וּכְלֵי עוֹר וּכְלֵי עֶצֶם שֶׁנִּשְׁבְּרוּ טִהֲרוּ מִטֻּמְאָתָן. חָזַר וְעָשָׂה כְּלִי מִשִּׁבְרֵיהֶם אוֹ שֶׁקִּבֵּץ אֶת שִׁבְרֵיהֶן וְעָשָׂה מֵהֶן כֵּלִים אֲחֵרִים הֲרֵי אֵלּוּ כִּשְׁאָר הַכֵּלִים הַטְּהוֹרִים שֶׁלֹּא נִטְמְאוּ מִקֹּדֶם שֶׁהֵן מְקַבְּלִין טֻמְאָה מִכָּאן וּלְהַבָּא. וְכֵן כְּלֵי מַתָּכוֹת שֶׁנִּשְׁבְּרוּ אַחַר שֶׁנִּטְמְאוּ טִהֲרוּ. הִתִּיכָן וְחָזַר וְעָשָׂה מֵהֶן כֵּלִים אֲחֵרִים חָזְרוּ לַטֻּמְאָה הַיְשָׁנָה. וְאֵין לִכְלֵי מַתָּכוֹת טָהֳרָה גְּמוּרָה עַד שֶׁיַּטְבִּילֵם בְּמִקְוֶה כְּשֶׁהֵם שְׁלֵמִים אוֹ יִשָּׁאֲרוּ שְׁבוּרִים:
When wood keilim, leather keilim, or bone keilim are broken, they are purified of their ritual impurity. If one then made a k'li from the broken pieces or one collected the broken pieces and made other keilim from them, these are considered like other pure keilim that had never contracted impurity previously and are susceptible to impurity from the time they were fashioned onward. All metal keilim that are broken after they contracted impurity regain purity. If one melted them down and made other keilim from them, they return to their previous impurity. A metal k'li cannot become utterly pure unless it was immersed in a mikveh while intact or it remains broken.
