Study Guide Pesachim 30 Today’s daf is sponsored by Rabbi Fredda Cohen in honor of her husband, Eric Nussbaum. "With much love for an amazing 47 year journey with many more years to go, 'אם ירצה ה. You are the most wonderful husband and father and you are a Saba Sababa." How do we hold regarding chametz that was owned by a Jew over Pesach that falls into a mixture (of non problematic food) on Pesach or after Pesach? Can it be nullified in the mixture or not? Is there an issue to use an earthenware vessel that was used for chametz before Pesach, after Pesach as the flavor will not come out into the food and it will be chametz that was left over Pesach, as earthenware vessels cannot be kashered? Rav and Shmuel disagree. The gemara tells that Shmuel used his lenient opinion as a threat to those selling new pots after Pesach to get them to lower their prices! Can one bake dairy bread? What is the issue? What types of utensils can be kashered? And how? Can eatherware ovens be kashered? What is the status of an earthenware glazed vessel? How are laws of glazed earthenware vessels different for cooking and storing wine? Why? If a Jew gives chametz as collateral for a loan or the reverse, what is its status after Pesach? Rava and Abaye disagree about when a collateral becomes the possession of the creditor in the event that the borrower doesn't pay back the loan - it is considered retroactively the creditors from the moment he/she received it? Or from the moment the loan is due and is not paid?
