Keilim30: 1
כְּלֵי זְכוּכִית, פְּשׁוּטֵיהֶן — טְהוֹרִין, וּמְקַבְּלֵיהֶן — טְמֵאִים. נִשְׁבְּרוּ — טָהֵרוּ. חָזַר וְעָשָׂה מֵהֶן כֵּלִים — מְקַבְּלִין טֻמְאָה מִכָּאן וּלְהַבָּא. הַטַּבְלָא וְהָאִסְקוּטְלָא שֶׁל זְכוּכִית — טְהוֹרִין. אִם יֶשׁ לָהֶן לִזְבֵּז — טְמֵאִים. שׁוּלֵי קְעָרָה וְשׁוּלֵי אִסְקוּטְלָא שֶׁל זְכוּכִית שֶׁהִתְקִינָן לְתַשְׁמִישׁ — טְהוֹרִין. קִרְטְסָן אוֹ שָׁפָן בַּשּׁוּפִין — טְמֵאִין.
[Regarding] glass utensils, their flatwares are tahor but their hollowares are tamei. [If] they break, they become tahor. [If] one remade [the broken utensils] into [new] utensils, they are susceptible to tumah from then on. A table and an iskutla made of glass are tahor. If they have a rim, they are tamei. [Regarding] the bottom of a plate and the bottom of an iskutla made from glass, which one has designated for use, are tahor. If he smoothed them or shaved them with a file, they are tamei.
