On our soda kiln we do use the same frame for several subsequent kilns, but
then it needs to be replaced, due to overall corrosion. When you were here
for TJ's BFA opening, you may not have taken a close look at our salt kiln.
It's been in use for six years, and is on its last leg - both the kiln and
the frame. The salt is just so corrosive, especially when you fire to cone
10 as often as we do. I am proud of the fact that we get six or seven years
out of each salt kiln. I build the frame out of 1/4x4" angle and 1/4x2x6"
channel, but the salt does its job in six or seven years, and it is amazing
to see that steel flaking away. If we sandblasted it once a year and
repainted it we could protect the outer surfaces, but the inside facing of
the steel against the brick would still be deteriorating.
