כְּלִי חֶרֶס אֵינוֹ מְקַבֵּל טֻמְאָה עַד שֶׁיִּהְיֶה מְקַבֵּל וְעָשׂוּי לְקַבָּלה. אֲבָל אִם לֹא הָיָה לוֹ בֵּית קִבּוּל אוֹ שֶׁהָיָה מְקַבֵּל וְלֹא נַעֲשָׂה לְקַבָּלָה אֵינוֹ מְקַבֵּל טֻמְאָה כְּלָל לֹא מִן הַתּוֹרָה וְלֹא מִדִּבְרֵי סוֹפְרִים. לְפִיכָךְ הַכִּסֵּא וְהַמִּטָּה וְהַסַּפְסָל וְהַמְּנוֹרָה וְהַשֻּׁלְחָן שֶׁל חֶרֶס. וְכֵן כָּל כַּיּוֹצֵא בָּהֶן מִכֵּלִים שֶׁאֵין לָהֶם תּוֹךְ אֵינָן מְקַבְּלִין טֻמְאָה. וְכֵן הַסִּילוֹנוֹת שֶׁהַמַּיִם מְהַלְּכִין בָּהֶן אַף עַל פִּי שֶׁהֵן כְּפוּפִין וְאַף עַל פִּי שֶׁהֵן מְקַבְּלִין הֲרֵי הֵן טְהוֹרִין מִפְּנֵי שֶׁלֹּא נַעֲשׂוּ לְקַבָּלָה אֶלָּא כְּדֵי שֶׁיֵּצְאוּ מֵהֶן הַמַּיִם. וְכֵן חָבִית שֶׁל שַׁיָּטִים וְחָבִית הַדְּפוּנָה בְּשׁוּלֵי הַמַּחַץ הוֹאִיל וְנַעֲשֵׂית כְּמוֹ בֵּית יָד שֶׁנּוֹשְׂאִין בָּהּ הַמַּחַץ וְלֹא נַעֲשֵׂית לְקַבָּלָה אֵינָהּ מְקַבֶּלֶת טֻמְאָה:
An earthenware k'li is not susceptible to ritual impurity unless it has a receptacle and was made with the intent that it serve as a receptacle. If, by contrast it does not have a receptacle or even if it has a receptacle, but it was not made to serve that purpose, it is not susceptible to impurity at all, neither according to Scriptural Law, nor Rabbinic decree. Accordingly, a chair, a bed, a bench, a candelabra, or a table made of earthenware or any similar k'li that does not have a receptacle are not susceptible to impurity. Similarly, a large pipe even though water passes though it, and even it is curved, and even when it holds water, is pure, because it was not intended to contain water, but rather that the water should pass through it. Similarly, a barrel used by swimmers is not susceptible to impurity. This ruling also applies to a cask at the side of the base of a large barrel , because it was made to serve as a handle for those who carry the large barrel and was not intended to serve as a receptacle.
