If pots are fired to bisque temperature (^06 range) in a kiln used for ^10
saltglazing, what's the likelihood that residual salt might fume the
bisqueware and affect the ware if it were glazed and fired in regular
(non-salt) reduction?
Later...Dave

We used to regularly bisque pots in a salt kiln at Camp Tamarack (now Camp =
Maas)
in Flint Michigan. We found that we could only bisque to 08 with impunity. =
But,
the memories of that experience are getting old, and I think we may have had
problems with hot spots in the kiln. =BFDon't turn your burners up too high =
and
you will volitalize less salt no? probably aslo depends on the clay body and
amount of salt left in the kiln after the last firing.

Hey Dave,
In my experience, there would be very little residual salt at cone 06.
Although in firing planters to 03 in a salt kiln, I have found some residual
salt in burner port areas where the temp has pushed 01+
The other factor, of course, is how heavily salted up is your kiln.
All the best, Peter Jackson

I fired salt in a 65 cu. ft. catenary for 20 years and have always been
amazed at the myths that surround this subject. When I had been firing
for about a year I recieved a commission that did not require salt
finish. I'll admit I was worried when I fired the kiln to cone 9
(flat), but when I opened it up there was almost no indication that salt
had ever been used. I reasoned that in order for me to get a really
good surface on my pots normally I had to throw in 12lb. of soda 1/2
table salt-1/2 baking soda. Since I didn't use any there were only a
few hints of salt and those were near the firebox. It was a really rich
surface on the bare clay(stoneware) and nothing on the porcelain.
Have a great firing.
From western PA where we get 93 sunny days a year. I'm still waiting
for the next 90.
