Hi All--

I have a burning question--can you bisque fire in oxidation and then glaze
fire in reduction? My problem is this--I am taking a workshop at
Arrowmont in July and the instructor would like for us to bring a couple
of bisqued items so we can start glaze testing right away (high fire salt
firing and other reduction techniques) my problem is that I only have an
electric kiln--it will go to ^10, but as of yet I have not tried it. I
have never seen this question addressed--any help would be highly
appreciated!

Thanks,

Kathy

Kathy ,

We bisque in an electric all the time ,to cone 08 ussually. That
should be fine for your situation as well.

Hi Kathy!

In many studio settings, it's a standard practice to bisque fire in oxy, prior
to glaze firing in reduction.

So go for it, and good luck in your workshop!

Milton of Yucca Valley...El Nino still prevails with cool (long sleeves
required)temperatures at night to gaze at the stars.

I'm off to Malibu (the 32nd California Men's Gathering beckons me) for the
weekend; I'll return to ClayArt when I return next week!

The answer is yes. BUT !!....Your clay body/bisque pieces must be made of a
clay body that can be fired to cone 10.....It is a very ugly sight to see
cone 6 bodies after fired to cone 10 and earthenware bodies will become a
flowing glaze-like mass that will possibly ruin kiln shelves and certainly
ruin any pots below and nearby..... Most clay bodies can be bisqued at cone
06-04. Just be sure of the upper firing limits of your clay body before
taking any bisque pieces to the class. If you currently glaze fire below
cone 10, get some clay from your supplier that will be appropriate for the
classes that you will attend. Supplier may recommend particular bodies for
salt firings. Bisque these pots with your regular work. Possibly add a
code number to signature to avoid any mix ups. Enjoy your classes. MB
