Ask Hamada. He did it for years.

Only if you are into séances.

In Topic: Trouble Getting Kiln Information

Yesterday, 08:08 PM

Your pictures show a good deal of information:

The kiln requires 45 amps; so your circuit will need a 60 amp circuit. Find a good electrician to look over the controller and do your wiring.
Max temperature looks to be 2300F -- cone 8, so your top temperature may be cone 6.
The kiln sitter is an older, Dawson manual model. Here is the manual for it: http://jenkenkilns.c...F/dawson-PK.pdfIt has three heating levels - low, medium, high. A starting firing schedule is two hours low, two hours medium, then high until your reach temperature. You will need to use cones to determine when you reach temperature.

The Jen-Ken site has a number of technical manuals; you might have to skim through them to see which might be helpful as one is not listed for the D-24 model.

Check with potters in your area to see if any fire a manual kiln. They can tell you a lot about how to proceed. There are also good books out there on firing an electric kiln that might be helpful.

In Topic: Number Of Firings

Yesterday, 07:52 PM

Potters once fire cone 6 clay with glaze applied to greenware  (might even have one or two on the forum who could give some pointers).  So, it is possible to eliminate your first bisque.  Will take some trial and error to get applications and firing right.

Is your kiln vented?  If yes, then leave the top down and peeps in; if not, you might want to leave the top peep out.  Lid hinges are really not designed to be propped open. 


My kiln is, so I leave the top closed and peeps in for both bisque and glaze firing. 

In Topic: Does A Lower Absorption Clay Actually Mean It's More Functional?

20 February 2017 - 07:09 PM

Might be more to do with thermal-shock value than absorption -- sitting under a heat-lamp for xx hours a day (followed by a somewhat quick cooling when the heat is turned off or it is put in water for cleaning) is likely stressing the clay body.  You might need to go to a flameware clay body or a clay body with kyanite or some similar material to increase its thermal shock capacity.
