Minimum amounts for liability when carrying out hair, clay, lime, earth, manure, sand, and reeds on שבת

Overview

This amud goes through the minimum amounts (שיעורים) that make a person liable for carrying things out on שבת. First a ברייתא gives the amounts for hair and clay. Then the גמרא explains the משנה's amount for lime, which leads to a side discussion about smearing girls with lime, the meaning of שמן המור, and the story of רב ביבי. Next the גמרא tries to define the words כלכול and אנדיפי in the dispute between רבי יהודה and רבי נחמיה. רב's explanation is rejected because of רבי's statement about dissolved lime versus lumps. The גמרא then tries several other explanations: lime on wine vessels, measuring marks (רב כהנא), and the forehead. A new משנה follows, giving the amounts for earth, manure, sand, and reeds. The גמרא explains the plasterer's trowel and asks whose view holds that sand improves plaster. It leaves רב אשי's question about the reed-pen as תיקו. Finally, it identifies the 'easy egg' as a chicken egg and sets the measure at a גרוגרת's worth of it.
