Hello,
Does anyone know of or know where I can find a few good salt glazes
c7-9?? Thanks Alot!!!!! Michelle

I chatted to a salt glazing potter today who told me that he uses slip on
the clay body and then fires to 1280 or above in reduction adding the salt
into the kiln at about 1250 with a final oxidation. He seemed to be using no
glaze at all just relying on the salt to attack and flux the clay body
giving the shine.

Dear Michelle,
I can give you a few glazes that work well for me at the ^7-8 range in my
wood-salt kiln. I changed these and other glazes (for reduction) from ^10 to
^ 7 with alot of testing. Basically, it was arrived through increasing or
changing the fluxes to ones with more alkalis and lowering the clay
(silica-alumina) content. This was before using and understanding INSIGHT
but through alot of failures I now have a few nice glazes at that temp. that
look like they have been fired to ^10-12 but have been fired to ^7-8.
Good Luck - Paul Wilmoth

I have found using oxide washes sprayed on bisque is a good sub for glaze on
salt fired pots. the salt caused the pots to glaze themselves and the
oxides inhanced the process.

"Terry Sullivan/Nottingham Center for the Arts. San Marcos," on mon 26 oct 98
I'm not knowledgable on salt glazes at all however came across two beautiful
effects years ago when briefly had access to a salt kiln in college.
Had fired a hand built bowl of smooth iron rich clay, think it was Laguna
"navajo", and we couldn't get the kiln high enough for the salt to fully
"glaze".
Made it to about cone 4-5 and surface was a dull mat.
On a whim; I put the piece into a 40 cu ft. mixed class cone 10 reduction
firing.
It came out a beautiful rich brownish red with a satin glaze.
Other was a small hand carved piece in a groggy red stoneware ( school mix )
on which I rubbed dry ball clay when it was med. leather hard. When fired to
cone 10 Salt it came out highly clear glazed and with a beautiful red/orange
color ( not tacky but very "natural" look.

Looking forward to building our first salt kiln this spring and playing.

Most of the glazes here are for a heavy
salting approximately 12-25 lbs. of rock salt.
Some of glazes have been used in a wood salt/soda kiln with less salt
and some soda, they seem to be fine.
Also it probably wouldn't be a good idea to reduced heavy at the end
after salting, I have seen the shiny glazes go gray and dull.
Good luck.
