הלכות טומאת מת כ״בDefilement by a Corpse 22

Halacha 1א׳

שׁוּלֵי הַמַּחֲצִין וְשׁוּלֵי קַרְקָעוֹת וְהַכֵּלִים וְדָפְנוֹתֵיהֶן מֵאֲחוֹרֵיהֶן אֵין מַצִּילִין בְּצָמִיד פָּתִיל בְּאֹהֶל הַמֵּת. קִרְסְמָן וְשָׁפָן וַעֲשָׂאָן כֵּלִים מַצִּילִין בְּצָמִיד פָּתִיל. שֶׁאֵין מַצִּיל בְּצָמִיד פָּתִיל אֶלָּא כֵּלִים:

The bottoms of large jars, and the bottoms of vessel-floors and of vessels, and their side-walls from behind, do not save by a tightly sealed cover in the tent of a corpse. If he trimmed them and smoothed them and made them into vessels, they save by a tightly sealed cover — for nothing saves by a tightly sealed cover except vessels.

Halacha 2ב׳

כְּלִי חֶרֶשׂ שֶׁנָּתַן בּוֹ טִיט עַד חֶצְיוֹ לֹא בִּטְּלוֹ. וְאִם הִשְׁקִיעַ בּוֹ אֶת הַכֵּלִים מַצִּיל:

An earthenware vessel into which he put clay up to half of it — he has not thereby annulled it. And if he sank the vessels within it, it saves.

Halacha 3ג׳

כְּלִי חֶרֶשׂ מַצִּיל בְּצָמִיד פָּתִיל עַד שֶׁיִּנָּקֵב בְּמוֹצִיא רִמּוֹן. וּבְגָדוֹל עַד שֶׁפָּחַת רֻבּוֹ. כֵּיצַד. כְּלִי גָּדוֹל שֶׁנִּפְחַת [חֶצְיוֹ] וְהִקִּיפוֹ צָמִיד פָּתִיל וְסָתַם מְקוֹם הַפְּחָת בְּצָמִיד פָּתִיל הֲרֵי זֶה מַצִּיל אַף עַל פִּי שֶׁאֵינוֹ חָשׁוּב כְּלִי לְעִנְיַן טֻמְאָה. אֲבָל כְּלִי הַמֻּקָּף צָמִיד פָּתִיל שֶׁהָיָה נָקוּב אוֹ סָדוּק וְלֹא סָתַם הַנֶּקֶב נִטְמָא וְאֵינוֹ מַצִּיל. וְכַמָּה יִהְיֶה בַּנֶּקֶב. אִם הָיָה כְּלִי הֶעָשׂוּי לָאֳכָלִים שִׁעוּרוֹ בְּמוֹצִיא זֵיתִים. הָיָה עָשׂוּי לְמַשְׁקֶה שִׁעוּרוֹ בְּכוֹנֵס מַשְׁקֶה. הֶעָשׂוּי לְכָךְ וּלְכָךְ מְטִילִין אוֹתוֹ לְחֻמְרָא. וּמִשֶׁיִּנָּקֵב בְּכוֹנֵס מַשְׁקֶה אֵינוֹ מַצִּיל עַד שֶׁיִּסְתֹּם הַנֶּקֶב אוֹ עַד שֶׁיְּמַעֲטֶנּוּ:

An earthenware vessel saves by a tightly sealed cover until it is pierced with a hole that lets a pomegranate pass; and in a large vessel, until the greater part of it has been broken away. How so? A large vessel half of which was broken away, and he closed it with a tightly sealed cover and stopped up the place of the breach with a tightly sealed cover — this saves, even though it is not reckoned a vessel with respect to impurity. But a vessel closed with a tightly sealed cover that was pierced or cracked, and he did not stop up the hole, has become impure and does not save. And how large must the hole be? If it was a vessel made for foods, its measure is a hole that lets olives pass; if it was made for liquid, its measure is a hole that lets liquid in; and one made for this and for that — they cast it toward the stringent side. And once it is pierced with a hole that lets liquid in, it does not save until he stops up the hole or until he reduces it.
