I find it interesting that Hannah Glasse specifies here that you may not use earthenware or stone crocks that have previously been used in your springhouse (“laid in water”). An edict to do the work on a fine clear day would reduce the amount of humidity captured in the pots with the preserved goods. At least that’s what I would say a “fine clear day” would be!
