Firing Services: Bisque, Glaze & Reduction

Many independent ceramic artists have approached us about having their work fired in our studio. To meet this demand we are offering firing services for experienced potters.    

These services are not for  beginner work  or people who are teaching elsewhere looking for a place to fire beginner work. 

EXPERIENCED POTTERS ONLY!

( We do not fire clay or glaze that is not tested in our studio.  We reserve the right to refuse service.)

*Due to high volume of work in our classes.   We are not accepting outside ceramic work to be fired in our kilns at this time.  - Mahalo

Bisque Firing Cost

All clay and glaze must be purchased from High Fire Hawaii Gallery & Studio.  Work must be clearly signed. We carry stoneware and porcelain that works well with our glazes and fires properly in our kiln.  25 pound bags of most clays are currently priced at $14.00.

We use Cone 5 – 10 stoneware and porcelain clay bodies.

We bisque fire to cone 07, which ensures that most organic material is removed from the clay and it is strong and ready for glazing.

Please make sure your work is bone dry before bringing it to our studio, especially larger sculptural pieces.

Pricing for bisque firing: 3 cents per cubic inch for most work.

Please note that the minimum height is 2.0 inches and
 flat work requires many kiln shelves.

Due to kiln spacing and post heights we round up to the nearest inch for height.

The electric kiln we use for most work has 3.27 cubic feet interior space including the space taken up by shelves and posts.

Maximum firing width is 14.75″ and maximum height is 18″.

Please note: Sculptural pieces must be hollowed out or no
 thicker than 1/4″.  We cannot accept heavy solid work. Please be certain your piece is completely dry before bringing it to our studio.
