This series explains how to build an electric kiln/furnace/oven, which can be used to melt metals, fire ceramics, burn out casting moulds (and make marshmallows).
In part 1 we start by cutting an old almond oil drum into the bottom and top lid pieces. Then fire bricks are cut to the correct shape to form an octagon shape, and finally they're mounted in the oil drum.
The silicate insulation material is also known as; calcium silicate and bio silicate.

Ive been working on the recipe for the insulated fire brick. Talc20%,ball clay25%,mullite55%. Thats a good recipe for alot of kiln furniture, like shelves, insulators for kiln filaments. Kiln stand offs, whatever. I did 2 small test bricks. 1 with old brown tree leaves i ground up and mixed into the clay and the other with packing styrofoam(EPS Foam) i ground into its individual cells. The foam and tree leaves are just filler to create voids in the brick to create the insulation properties and light weight and I think I did 50/50 by volume and think theyre a little dense and you could go harder on the burn off substrates, But definitely usable at 50/50. Then I fired it at cone 10 and left the kiln lid cracked for maybe 30 minutes as the burn off stuff produced smoke. Then closed it and ramped it. End result is 2 usable insulated firebricks, althoug 2"x4"x.5" (since it was just a test) and no damage to the kiln. Thats probably useful if you can source the raw ingredients cheaper than the bricks and or want to build bigger kilns out of smaller kilns.

How many hours of research did you do before making the first drum cut? What 3d program did you use? Did this program determine design solutions? I'm very interested in diy and can see myself doing every step of this project simply because knowledge if tools impacts craftsmanship. I appreciate your emphasis on quality tools but also appreciation for your neighbour's drill. I am fascinated with the calculation of the wiring, probably because I am not an electrician. How long did the project take from concept to completion?

I see you don't have thermal insulation other than the firebricks. Is it enough? What temperature do you measure on the outside of the barrel, when inside it is 1300 degrees Celsius?

I am very curious as to what type of element you used (the diameter of the wire) and how you wired everything. I'm also making an electric kiln but somehow mine does not go above 780 C, still trying to find out if it's the thermocouple, the wire or bad insulation.

Hi Thomas, I am working on part 2 of this series these days and hope to release it by the end of this week. It includes the calculations for designing your own heating elements :) How many kilo watts are your kiln and how well is it insulated? Kind regards

@@jakobhalskov Hello Jakob, thank you for the quick response and interest! I look forward to the follow-up video. If you can, please include where you bought the wire because I had a hard time finding a decent supplier. About my own kiln project; yesterday I found out that the heating element wire has burned through at 2 of the points where I made a connection to the wiring of the electronics. I think I bend it too much. So I need to fix that first to see if it still won't go higher than 780 C. My kiln is pulling about 3000 watts, maybe a bit more. Insulation is a bit like yours, firebricks (type 26 or 28) first and around those a 'ceramic wool blanket'. I used a big old Miele centrifuge from the 50's for casing. Thanks again, hope to hear from you! Kind regards.

@@Thomas-Almanza You are very welcome Thomas! I am wondering how long it takes for your design to reach 780 °C; for my 5 kW design ( closer to 4.5 kW in practice ) it takes 110 minutes to reach 790°C. In the end it is all a matter of how much energy is put into the 'system' vs how much escapes through the insulation/gaps in the kiln. I purchased my "1.4mm Kanthal D wire" from a German supplier called "Evek GmbH" which has fair prices and ships to Denmark where I live. Looking forward to hear from you and see if you can achieve higher temperatures. As you will see in a future video I can achieve >1100 but also managed to melt my SSR relays and PID controller partly.. Kind regards Jakob

Can the bricks be written on? I can’t help but think it would go easier if marked say, layer ‘x’ with an arrow facing up & maybe adding a special character for the slanted bricks for the element channels that go to the next layer. It would be my luck to mistakenly mix up the bricks.

No, ytong contains some cement, which is not so heat-resistant! Fire brick is a dense brick made of fire clay, and stands at least 1515 °C, while ytong is porous and fragments at 800-1200 °C.

Regarding your saw never being the same again, you can sharpen the saw with a saw sharpening file. You may have to do this a few times when cutting the bricks as the teeth wear. Here is but one of many videos showing you how to sharpen your saw: kzfaq.info/get/bejne/m52Jps18zdfPXas.html
