the lid may present trouble but it really depends on how the kaowool is
placed in the lid. most people would probably just cut two circles and
place them in the lid. this would present a problem unless some
rigidizer was used on the circles. i was thinking about making strips
three inches wide by 1 inch thick as long as the roll. wind the strips
in the lid in a spiral until i get to the exhaust hole. i also toyed
with the idea of painting the strips with sodium silicate. i have one
gallon of sodium silicate.

or i could just line the lid with the homebrew refractory.
