Mishnah 1א׳

מַחַט אוֹ טַבַּעַת שֶׁנִּמְצְאוּ בִנְחֻשְׁתּוֹ שֶׁל תַּנּוּר, נִרְאִין אֲבָל לֹא יוֹצְאִים, אִם אוֹפֶה אֶת הַבָּצֵק וְהוּא נוֹגֵעַ בָּהֶן, טָמֵא. בְּאֵיזֶה בָצֵק אָמְרוּ, בְּבָצֵק הַבֵּינוֹנִי. נִמְצְאוּ בִטְפֵלַת הַתַּנּוּר מֻקָּף צָמִיד פָּתִיל, אִם בְּטָמֵא, טְמֵאִין. וְאִם בְּטָהוֹר, טְהוֹרִים. נִמְצְאוּ בִמְגוּפַת הֶחָבִית, מִצִּדֶּיהָ, טְמֵאִים, מִכְּנֶגֶד פִּיהָ, טְהוֹרִים. נִרְאִין בְּתוֹכָהּ אֲבָל לֹא לַאֲוִירָהּ, טְהוֹרִין. שׁוֹקְעִים בְּתוֹכָהּ וְתַחְתֵּיהֶם כִּקְלִפַּת הַשּׁוּם, טְהוֹרִין:

A needle or a ring which was found in the floor of an oven, and they can be seen but do not protrude into the oven - if one bakes dough and it touches them, [the oven] is impure. Regarding which dough did they speak? With regard to ordinary dough. If they are found in the plaster of an oven with a tightly fitting lid: If [the oven is] impure, they are impure; if [the oven is] pure, they are pure. If they are found in the stopper of a jar: If on the sides, they are impure. If opposite the mouth, they are pure. If they can be seen in it, but they do not enter its airspace, they are pure. If they sink into it, and there is [plaster] underneath them as thick as garlic peel, they are pure.

Mishnah 2ב׳

חָבִית שֶׁהִיא מְלֵאָה מַשְׁקִין טְהוֹרִין וּמְנִיקָת בְּתוֹכָהּ, מֻקֶּפֶת צָמִיד פָּתִיל וּנְתוּנָה בְאֹהֶל הַמֵּת, בֵּית שַׁמַּאי אוֹמְרִים, הֶחָבִית וְהַמַּשְׁקִין טְהוֹרִין, וּמְנִיקָת טְמֵאָה. וּבֵית הִלֵּל אוֹמְרִין, אַף מְנִיקָת טְהוֹרָה. חָזְרוּ בֵית הִלֵּל לְהוֹרוֹת כְּדִבְרֵי בֵית שַׁמָּאי:

A jar that was full of pure liquids, with a siphon in it, and it had a tightly fitting cover and it was in a tent in which there was a corpse: Beit Shammai says: Both the jar and the liquids are pure, but the siphon is impure. And Beit Hillel says: The siphon also is clean. Beit Hillel reversed its position and ruled in agreement with Beit Shammai.
