Shabbat 50a and Shabbat 50b, more muktzeh issues, because of the question of a what to do with a pot insulated with muktzeh items. From there, to what we need to do to turn an item into one we are allowed to consider usable on Shabbat, and from there into issues of personal hygiene (which materials we can use to wash ourselves on Shabbat, and what kinds of washing are appropriate hygiene, what are excessive). Then back to hatmanah with a muktzeh item.
