Commentary for Avodah Zarah 66:11
א"ר זביד האי מאני דקוניא חיורא ואוכמא שרי ירוקא אסור משום דמיצריף ואי אית בהו קרטופני כולהו אסירי דרש מרימר קוניא בין אוכמא בין חיורא בין ירוקא שרי
R. Zevid said: These glazed vessels, if white or black they are permitted, but if green are forbidden because it contains crystals of alum; and if they have any cracks [in the glazing] they are all forbidden. Meremar expounded that all glazed vessels, whether black or white or green, are permitted.
Daf Shevui to Avodah Zarah
White and black glazed vessels do not absorb the taste of the wine, but the green one’s might, so they are prohibited. And cracks will let the taste go into the vessel, so they are prohibited.

Daf Shevui to Avodah Zarah
This whole section is an extended difficulty on Meremar, a late Babylonian sage. Meremar allowed all glazed vessels that had been used with non-Jewish wine. He seemed to think that such vessels do not absorb. But when it came to vessels that had been used with hametz before Pesah, he ruled much more strictly, prohibiting all of them. He saw that they “sweat,” meaning they emit liquid when heated, and therefore he assumed that they also absorb. And once an earthenware vessel has absorbed taste, there is no way to “kasher” it.
