Ive got some bentonite now, along with zircon, so in about 2 weeks when i go home next, Ill be able to put together my forge, and will be testing this mixture, using it to coat the forge, and im going to try and make some burners out of it.

The initial yellow flames are from the fuel I used to preheat the coil at the front of the burner. This new update increased the fuel flow which successfully prevented burning back in the tube. A check valve was also added closer to the burner to stop the back pressure , which would cause it to burn inconsistently. In the video I adjust the fuel pressure slightly testing it out. Next changes are going to be a longer fuel line, moving the fuel inlet further back, and increasing the diameter of the heating coil.

Usually yes, I wasn't sure because it seems often mortars etc go by volume, thank you

Yes, being very careful, and I'm exploring with fuels other than oil, and one a small scale Yes of course! I'll upload them tonight

Naturally aspirated liquid fuel burner, made some significant progress today. IMG_1733.MOV

I've been doing some experimenting with a liquid fuel burner of my own design, with frequent changes, and decided to document it on a thread. Any suggestions are welcome. the first two videos are of it running with methanol, which didn't work outside the forge, the flame would go out just as it would start vaporizing. The second video is it running with white gas, which improved the fuel air mixture (3.5 times more fuel/air) IMG_1704.MP4 IMG_1705.MP4 IMG_1724.MOV

I did read that, 3-5%. Sorry I just got mixed up with the old ratio from the kaolin mixture. Is it by weight or by volume?

Ah okay, I wasn't sure if the mixture of kaolin and zircon would work, because it was based on the itc. Thank you guys for clearing that up, reading the thread it seemed like it was a common solution. Fortunately I can get bentonite at the pottery supply nearby. So just to clarify, I would mix the bentonite and zircon, in about a 30/70 mix, by weight or volume? Then I can paint it onto the rigidized insulation?

Hi, I'm designing/building a miniature forge for casting as well as small blacksmithing. It will be a cylinder vertical forge, and have 2 inches of the ceramic wool insulation. So far I've purchased for the build, 2300f ceramic wool, wool rigidizer, and ultrox 500 zircon. My questions are related to how to put the forge together and what other materials are required. Yes I have read the forges101 thread, just wanted to clear some things up -after placing the wool, rigidizing, and drying into the forge lining, should I just paint on a mixture of the zircon with epk kaolin clay as a binder? Would that have issues cracking apart? If that's correct, is there anything specific to watch out for ? Thank you! ill attach some pics of an experimental forge I made with plaster and methanol for entertainment, as well as a cool tube furnace I found in one of the labs at my university. IMG_1704.MP4
