i beg to differ . i have built several coffee can furnaces with the lid
painted with sodium silicate and allowed to dry and harden exposed to
carbon dioxide. i than coated the lid with itc-100 on both sides and the
exhaust hole. these coffee can furnaces have lasted for years. i see no
indications that the sodium silicate has melted.

believe me if i had some rigidizer i would use it. however, i do not
have rigidizer and since my pauper status has not change i am not going
to be buying any.

for the crucible furnace lid i will probably just ram it with the
homebrewed mixture since i have all ready mixed it up. the crucible
furnace body will be two layers of kaowool the inner layer coated with
itc-100. the crucible furnace bottom will be lined with the homebrewed
mixture because to it durability to the flame impingement. i will just
use the glass, fire clay, and borax glaze on the lid and bottom.
