Study Guide Shabbat 48 Today's daf is dedicated in honor of a number of birthdays. In honor of Akiva Blander's birthday by his parents, Peri Rosenfeld and Stuart Blander. He lights up our lives with his wry humor and his ongoing support of our learning the daf. In honor of Rivka Greenstone’s birthday from her parents David and Shira. And in honor of my son, Moshe’s birthday.  Two events happened in the house of the Exilarch in which Raba was critical of the behavior of a servant - one regarding hatmana/warming water on Shabbat and one regarding covering a barrel with a kerchief. If one uses pieces of wool generally used for making clothing, but one time it was used for hatmana, would the wool be allowed to be carried on a different Shabbat as it was at some point useful on Shabbat? Can one refill the wool stuffing of a pillow if it falls out on Shabbat? Can one put the stuffing in to make the pillow? What about cutting out the part for the neck of clothing or untying the neck that was sewn together by the launderer? The gemara then talks about uncovering a sealed barrel - is that the same as cutting out the part for the neck in a new shirt? The gemara then discusses different issues regarding items that are temporarily connected - are they considered connecting for purity/impurity issues? On what does it depend?
