HI ALL!
My partner and I are planning to build a salt kiln...We haven't much
experience in firing a salt kiln and no experience with soda. Our
question is to those of you who have fired with both, which do you like
better and for what reason? All replys are most appreciated and any
information given may or not be used in our decision ;),
Thanks for your support,

Becky:
You may want to try to get some experience firing both types of kilns
(salt and soda) before making your decision. Soda fired and salt fired
pots are similar in many ways, but very different as well. Some potters I
know go to great lengths to make soda fired pots look like salt fired
pots. However, both types offer beauty all their own. Explore and
appreciate each type in its own right.
-Bill

Salt is less polluting and works better. Nils

If you are in Kentucky go ask Byron Temple or Rand Heazlit(sp?) who have
their studio up in Louisville/ New Albany or ask Joe Molinaro at Eastern
Ky U. There are other potters that salt in Ky - Greg Seigal(sp?)...My
guess is that soda would be more economical in the long run - less toxic,
less wear on furniture and shelves and kiln.
Good luck

Dear Nils,
I have done salt for a number of years and I personally agree
that it works better for my personal aesthetic.
What you have confused me on is the poluting factor. I always
thought that soda gave off less polution than salt (which yields chlorine
gas then turns into hydro-chloric acid gas once it has come into contact
with air moisture). Am I mis-informed about what is exiting my chimney?
Thanks - Paul W.

Paul, Apparently, many of us have been mis-informed according to Wil
Shynkaruk at Utah State who delivered a paper at NCECA on this subject.
Without going into details of his exhastive effort his conclusions were
that less than 1% of the salt used in a typical firing was actually
consumed in sodium combining with silica for glazing effects and the rest
was exhausted through the flue and into the atmosphere AS SALT AND WATER
VAPOR. The stuff our mothers use on us when we have a sore throat. As for
clorine gas, NONE was measured in the stack and HCL production was so
small as to be difficult to measure.
Soda firings on the other hand (soda bicarb, soda ash etc)
produce fumes and buildup of caustic soda, in my mind, somewhat more
hazardous residue than salt water.
This explains the "mystery" of how old salt workers in potteries
in Germany and France survived. I have seen them standing on kilns salting
and intentially breathing in the fumes when salting as it "cleared their
sinuses"
Finally, the saltware industry wasn't replaced because it was
demonstrated that the process was hazardous. It was strictly an
economically feasible decision as competitors produced sewer tile more
cheaply by glazing it.
I am paraphrasing most of this as Wil's innovative study has been
sorely needed and those of us who love salting can apparently rest easy
with no guilt. Nils
