Best Literature To Learn How To Stack A Gas Kiln?

25 April 2017 - 12:42 AM

Is there a book/article on the details of loading a kiln? I need to learn more about it.

I'm just about finished with my gas kiln. The burners enter horizontally on the back wall and the exit flue is also on the back wall. The width of the chamber is 32 inches and the depth is 25 inches. The stacking area is 24 x 24 giving 4 inches on either side of the stack for the flames. Do I need to use a bag wall as part of the stack along side the flame channels?

What Colors Are Selling This Year?

04 April 2017 - 08:20 PM

I am gearing up to sell my flutes. My color pallette preferences might be very different than other people's. So, I was wondering if some colors sell better than others. I remember someone said browns don't sell as quickly. What has been your experience? What colors are hot and what colors are not?

Metal Frame For Sprung Arch Kiln

23 March 2017 - 12:46 PM

I still have to place the arch on my backyard kiln. But I need more help, please.

1. Do I need to brace the kiln edges with angle iron before I place the arch?

2. When I build the angle iron frame, do I snug it as close to the brick as possible or do I give it "wiggle room?"

3. Some designs use Springs to deal with heat expansion. Do I need this. My kiln outer dimensions are 47" wide x 43" deep with a 36" high stem wall. Does this the angle iron bracing?

4. All suggestion are appreciated.

New Crop Of Flutes. I Need Critiques

23 February 2017 - 04:17 PM

I just finished 10 new flutes. I am experimenting with glazes and clay bodies on the different flutes.  I just tuned these 6.  I would like your thoughts.  The tape ( red and black) is used to tune them. Eventually each with have an ornamental figure to replace the tape.

 

Can I upload a audio file of the flutes to the forum?

How Much Does A Refractory Castable Shrink On First Firing?

09 January 2017 - 03:09 PM

The sidewalls of my kiln project are built. The outside of the wall is 4" of hard brick and the inner liner is 4.5" of k26 IFB. The chamber is 30.5" wide x 25" deep x 24" high.

I had planned on making the arch as a monolith from a castable. But I worry that the castable will shrink too much during firing and collapse.

So here are my questions....

1. What is the percent shrinkage?

2. Would it be better to cast the arch in sections, like large bricks, fire the sections in another kiln, then assemble thems?

3. Or anybody know where I can get a good price on #1 arch bricks?
