Keilim16: 6
[ו] קַסְיָה שֶׁל זוֹרֵי גְרָנוֹת, שֶׁל הוֹלְכֵי דְרָכִים, שֶׁל עוֹשֵׂי פִשְׁתָּן — טְמֵאָה. אֲבָל שֶׁל צַבָּעִין וְשֶׁל נַפָּחִין — טְהוֹרָה. רַבִּי יוֹסֵי אוֹמֵר: אַף שֶׁל גָּרוֹסוֹת כַּיּוֹצֵא בָהֶן. זֶה הַכְּלָל: הֶעָשׂוּי לְקַבָּלָה — טָמֵא; מִפְּנֵי הַזֵּעָה — טָהוֹר.
The [leather] glove of winnowers, of wayfarers, [or] of flax workers, is tamei. But [the glove] of dyers or blacksmiths is tahor. R’ Yose says: Also, the [glove] of bean grinders is the same as they. This is the general rule: [A glove] that is meant to hold [things] is tamei. [But that which is used] because of perspiration is tahor.
