In addition to mica to control heat, some potters "stuccoed" the exterior
of pots with clay to control heat. I have examined stuccoed pottery, but
really do not understand how this helps in heating. Any ideas?

Mica could enter the pot as temper (with quartz sand) as micaceous
sandstones are not uncommon at least in Europe.
I came across an interesting example recently from a kiln in Swansea, S
Wales. it produced pots which appear t be late C15/early c16 in date
paralleling similar vessels from the Cotswolds (Minety area) suggesting
a source for the potter. The Cotswold pots are tempered with oolitic
limestone but the Swansea pots appear to have been tempered with an
oolitic sand probably from a beach along the nearby Gower peninsula. The
pots re unknown from consumer deposits so it looks as if the kiln was
short-lived- possibly not much pot being used in this period which seems
to be dominated by English and Continental imports.
