Commentary for Avodah Zarah 66:2
בעא מיניה ר' יהודה נשיאה מרבי אמי החזירן לכבשן האש ונתלבנו מהו א"ל ציר שורף אור לא כ"ש אתמר נמי א"ר יוחנן ואמרי לה אמר ר' אסי א"ר יוחנן קנקנים של עובדי כוכבים שהחזירן לכבשן האש כיון שנשרה זיפתן מהן מותרין
R. Judah Nesi'a asked of R. Ammi: What if he put them back into a furnace, so that they became heated to a very high temperature? He replied: If brine has a cleansing effect on them, how much more so fire! It has likewise been stated: R. Yohanan said (others say that R. Assi said it in the name of R. Yohanan): Flagons of idolaters which had been placed back in the furnace, as soon as the pitch has fallen off, are permitted.
Daf Shevui to Avodah Zarah
One can kasher earthenware wine vessels belonging to non-Jews by putting them back into the furnace. The heat will burn out any of the prohibited substance. R. Ashi adds that even if the pitch covering the inside of the vessel was only loosened and did not fall off, it is still permitted.
