Mishnah 1א׳
הַקַּלָתוּת שֶׁל בַּעֲלֵי בָתִים שֶׁנִּפְחֲתָה פָחוֹת מִשְּׁלֹשָׁה טְפָחִים, טְמֵאָה, שֶׁהוּא מַסִּיק מִלְּמַטָּן וּקְדֵרָה בְשֵׁלָה מִלְמַעְלָן. יָתֵר מִכָּאן, טְהוֹרָה. נָתַן אֶבֶן אוֹ צְרוֹר, טְהוֹרָה. מֵרְחָהּ בְּטִיט, מְקַבֶּלֶת טֻמְאָה מִכָּאן וּלְהַבָּא. זוֹ הָיְתָה תְשׁוּבַת רַבִּי יְהוּדָה בְתַנּוּר שֶׁנְּתָנוֹ עַל פִּי הַבּוֹר אוֹ עַל פִּי הַדּוּת:
The fire-basket of a householder which was decreased in size to less than three tefachim is susceptible to impurity, because when it is heated from below a pot above would still boil. If [it was decreased in size] further, it is not susceptible to impurity. If [subsequently] a stone or gravel was put into it, it is still not susceptible to impurity. If it was plastered over with clay, it may contract impurity from that point onward. This was Rabbi Yehudah's reply regarding the oven that was placed over the mouth of a cistern or over that of a cellar.
Mishnah 2ב׳
דָּכוֹן שֶׁיֶּשׁ בּוֹ בֵית קִבּוּל קְדֵרוֹת, טָהוֹר מִשּׁוּם כִּירָה, וְטָמֵא מִשּׁוּם כְּלִי קִבּוּל. הַצְּדָדִין שֶׁלּוֹ, הַנּוֹגֵעַ בָּהֶם אֵינוֹ טָמֵא מִשּׁוּם כִּירָה. הָרַחַב שֶׁלּוֹ, רַבִּי מֵאִיר מְטַהֵר, וְרַבִּי יְהוּדָה מְטַמֵּא. וְכֵן הַכּוֹפֶה אֶת הַסַּל וְעוֹשֶׂה עַל גַּבָּיו כִּירָה:
A hob that has a receptacle for pots is not subject to impurity under the laws of a stove, but subject to impurity as a receptacle. Whatever touches its sides does not become impure under the laws of a stove. Its wide side: Rabbi Meir holds it to be pure, but Rabbi Yehudah holds it to be impure. The same law applies also when one turns over a basket and makes a stove upon it.
