Do you have any tips on care and maintenance?

Kaiser Lee Board is easy to carve so be careful when you place something into your kiln not to scratch it. If it gets scratch the side walls it does not have any influence on the performance of the kiln - just cosmetics. If you scratch the floor of your kiln you will see it in the back of your glass.

If the floor of your kiln is not treated with kiln wash it is easier to smooth the shelf with a knife sharpening or soft sanding block. Use only little pressure and go over it lightly.

Could you do 2 full fuse projects in a day?

Depending on the firing cycle and the timing you might be able to do 2 firings. One early in the morning and the other one later in the afternoon. If the glass is still a little bit hot I would cover it with fiber blanket. Fire on a piece of Kaiser Lee Board as a kiln shelf - open the kiln around 200 F and put the fiber blanket right on top and take both out of the kiln and place them somewhere safe.

One huge advantage of fusing with Kaiser Lee Board molds is that you can do many projects in one firing - full fusing and slumping in one firing. It also enables you to do certain projects that would otherwise be impossible.  

Would a slumping schedule be the same as for conventional kilns?

Yes you can use the schedules you are familiar with. But when you are using fiber products for kiln furniture only, then you can change your schedule.

 

Do you have to use kiln wash on the base of the kiln?

If you want to kiln wash the base - which doubles as a Kaiser Lee Board kiln shelf use either Boron Nitride or Primo Primer. But we do not recommend it for reasons explained below.

In Germany I learned to use only kiln wash in its dry stage - just powder it onto the shelf and add more as needed. You have to be care full when placing your glass on it so that you don't get any on top of the glass, but other than that it works fine.

If I do a project where I’m damming glass is it ok to put a small kiln shelf on the base of this kiln?

Yes you can but we recommend working with Kaiser Lee Board shelves and pieces of Kaiser Lee Board for damming - it is very reliable, reusable endless times, you won't have any seepage and nearly no bubbles since the air can escape easily.

Can I use no release at all?

Yes you can, glass does not really stick to Kaiser Lee Board. It will pick up some of the particles and will be rough on the back - which could be good in the case of wall mountings like tiles or back splashes.

Iridescent or dichroic glass does not stick to the board either if you are using the coated sides toward the board.

Will the glass ever stick to the base of the kiln?

The only time I have glass picking up a junk of fiber is when I melt glass to its liquid stage for raking. I'm using a different kiln and a designated Kaiser Lee Board for this process.  

Another issue could be, if you treated  the shelf with regular kiln wash. This type of kiln wash is known to stick to the glass sometimes and than it will rip our fibers from the shelf. So please never treat your kiln floor with regular kiln wash.

Should you use shelf paper?

I use shelf paper if I want a smooth backing or if I do "construction" art work with many pieces.

Can you give me some type of idea or typical fusing schedule?

Here are 2 fusing schedules that are typical when using Kaiser Lee Board as your choice of kiln shelf and mold.

 • Ramp up 600°F per hour to 1000°F and hold for 10 minutes

 • Ramp up as fast as possible (full = the setting after 0) to 1420°F hold for 10 to 20 minutes or desired result is achieved.

 • Ramp down full to 960°F and hold for 1 hr

 • Ramp down 100° F per hour to 750°F hold 1 min.

 • Let cool to room temperature.

 

If a piece is already fused and has to be re-heated again I only change the ramp up from 600°F to 300°F per hour.

All you need to adjust now is the target temperature for slumping and draping.

The biggest and most energy efficient kiln running on regular household currency. All you have to do is plug it in and fire your glass.

This kiln is built with Kaiser Lee Board only - the material we have been glass fusing with in the past 15 years. Since Kaiser Lee Board is holding up very well, we started developing glass fusing kilns. With the help of Jen Ken Kiln we have a beautiful product now.

Kaiser Lee Board reflects the heat and does not absorb it. You will be able to touch the board on top of the kiln while it is at full fuse temperature. Since you can fire very close to the edge, you can fit a 15" x 15" piece of glass inside the 16" x 16" x 6" firing chamber. The Orton digital controller is easy to program and we will send you easy to read instructions as well. It fires on 110 Volt and 15 to 20 Amp.You will be able to fire pieces up to 5" high since the KL-board floor doubles as a built in kiln shelf.

The Orton digital controller is easy to program and we will send you easy to read instructions as well. It fires on 110 Volt and 15 to 20 Amp. For only $1,199 you will be getting an all inclusive kiln, a 1 hour free phone consultation (preferable on Skype), my book “Glass Forming with the Mold Block System” and 1 Year Limited Warranty.
