To the list
I recently posed a question to the list in regards to salt vs. soda
emissions. From what I have been told soda is the more environmentally
friendly of the two and therefore, I assume the less hazardous to human life
as well. The question is, what is the minimum safe distance a soda kiln can
be in relationship to neighbors?
The kiln I have planned will be between 20 and 30 cu.ft. and probably only
fired once every month. Yet, I am concerned for my nearest neighbors who are
about 100 or so yards away.
In college I had the fortunate experience of burning lungs from the salt kiln
and only had the opportunity to fire soda maybe 3 times. Even though I am
sure the fumes dissipate and the primary affects are localized I would like
to get some opinions from the list.
Thank you
Anthony

The primary sodium emission of a soda kiln is, not surprisingly, in the
form of soda. There will also be a small amount of NaOH, but probably
vanishingly small, unless you actually stick your head down the flue. As
in the case of a salt kiln, the primary emission of such a kiln is neither
soda nor salt, but CO2, CO, and other combustion byproducts. The primary
long term hazard is combustion emissions and heavy metals. The latter is
unlikely to be a problem. The former (combustion products) is a
contributor to atmospheric pollution such as smog, and is controlled in
many municipalities.
Your neighbour, if downwind, may catch a whiff of soda when wind and other
weather conditions pull the smoke down on him. A kiln in heavy reduction
might give more smoke, and the only increased exposure factor is the
increased density of the salt/soda smoke/mist, which increases it's
tendency to hug the ground.
Of course, the plume of mist from a salt or soda kiln during
salting/soda-ing(?) is highly visible, and in this day and age might raise
anxieties.
I know of no standards for distance from such a kiln. In municipalities,
such standards tend to refer to air quality, and nuisance, not to distance.
Certainly there are many salt kilns which have been operated much closer
to neighbors than that. How many may have raised complaints, I have no way
of knowing. Perhaps others on the list will report their own experiences.

The Soda Vapor panel at NCECA essentially squelches the notion that soda
is more environmentally "friendly" than salt. Wil Shyrunkuk of Utah State
presented a comprehensive argument that approximately 99% of the salt that
goes into a salt firing emerges as SALT. There is no chlorine gas produced
and the only HCL acid was minuscule and measured in the stack only. As for
soda the effluent produced was caustic soda and was in significant
amounts. The other panelists concurred with these findings from their own
experience. Old timers in Germany, for instance, cleared their sinuses by
purposely breathing in the salt fumes emerging from the salt fireboxes.
Most of them were around 75 years old. It appears they were breathing in
salt and water vapor just like mom said to do
Salt with a clear conscience--have fun!, Nils
