Thanks Latticino, I figured the cones were related to time as well as heat. That's why I wanted to see if there's a formula for picking the right ones. I'll experiment with a few and at multiple levels. The kiln is programmable with display and an "Even heat" lining, so it 'should' be fairly even, but I tried to anneal a farriers rasp in it and it didn't turn out as annealed as the same brand that I heated up in a forge and stuck it in vermiculite. That's why I wanted to do some testing.

I recently purchased a used RioGrand kiln and would like to use witness cones near my piece to confirm it's getting to temperature. My wife uses them in her pottery kiln and wondering if I would use similar style cones for getting a tool to 1575 fahrenheit and holding for 1/2 hr. I'm sure the temperatures will be different depending on how high or how close to the wall my piece is. That's why I want to test several areas inside the kiln. Anyone have any experience with them?

Thanks both of you for the insight. I'm guessing flame color is something to think about for not oxidizing the steel.

I'm trying to dial in the Chile Forge I picked up cheap and rebuilt. Not having much experience with this nice of a forge and less than a year of working with a Mr. Volcano one burner as my only gas forge, I could use some advice! I've attached a video with one burner just after lighting it so it's easier to see. 5 psi with a .040 mig tip that Chile Forge recommended for my altitude of 5100 ft. (Fort Collins, CO)questions: Questions: 1. For general forging, what color should the flame be? Teal, Blue or light blue? 2. What color for forge welding if I attempt it? Teal, blue or light blue? I've been told by other Chile Forge owners in my area that 5-6psi for general and 10-15psi for forge welding. VID_20230305_072600609.mp4

Getting closer to insulating and lining it. End caps rebuilt, Burners rebuilt with parts from Chile Forge and test fire complete. VID_20230221_202459027.mp4

I was lucky enough to aquire 2 used Chile Forges the Cayenne model. One with burners that needs a lot of work and one gutted frame only. Has anyone had any luck relining them and reworking the burners and frames? I'm in contact with the Starrs at Chile Forge and waiting for their response, and I'm sure they will give me all the information and parts I need. But thought I would ask this group if anyone was successful we a rebuild. Looks like I'll have to hack away at the burner nozzles to get them out. I was thinking of trying out Superwool XTRA that is new and a lot safer to handle. Still plan to take precautions. I'm fairly new to blacksmithing but already have assembled a Mr volcano and built 2 coal forges... But I have a lot to learn...
