Dear Ray:
You may want to go back and read some of the archived threads about the new
findings with salt kilns. It seems that they are much less polluting than soda
fired kilns!
There was an extensive article on this a few issues back in Ceramic Review
from England, citing the tests and findings done on the two types of firings.
Regards,
June

There are evidentely two articles, one in the November/December 1996 issue #
162 and one in issue #157 1966.
I only have the later issue.
You should check some clayart archives as well. Someone recently posted the
results of tests done both with salt and sodium and the salt won, hands down,
on the emissions test.
Now I suspect one might want to look at the whole picture. Since salt fired
kilns deterioriate quickly, then there's the added pollution factor of mining
more clay for new bricks, pollution of making and firing them as well as
shipping them, etc. :-) I suspect that all in all the salt may still have
the edge. Maybe someone who knows how to figure this all out will post their
ideas.
I built my salt kiln with the intent of salt firing down the line and then
decided to use soda instead because of the pollution factor. After reading
recent reports, it seems that I am now leaning toward using the salt instead.
Regards,
June (who still needs to re-build her bourry boxes and do a salt firing in her
wood kiln!)
