Let me clarify. The frame was above the fire, not in the coals. I heated one section at a time for about 1 minute, then removed it to scrape the paint in that section. Each section worked was roughly 6 inches long. The total process, section by section, took about an hour.

I’ve never heard of anyone using flame to strip paint but lots of people use heat guns to do it. Ive used it on small parts.
Also- what paint stripper were you using? I found the spray-on stripper works way better than the brush on type. No idea why. It just did.

A heat gun is affordable, works quickly with little or no damage to the matrix under the paint, including most woods when used carefully.
Years ago when I lived in a rural home on 3 acres I went through a phase of experimenting with all kinds of primitive techniques for woodworking, etc., including metallurgy I experimented with old school heat treating to make knives from worn out files, and to make simple flat sprints from metal stock. It's possible to do pretty decent work with just a hot wood coal fire in a garden, both softening and hardening, including case hardening with bone.
But I'd hesitate to use an open flame or coal pit like that for removing paint. A heat gun would be easier and safer.
I'd also want to get an idea of the frame joinery and minimize heat time on joints.

Next time pay the powdercoat guy 125 bucks to strip it clean as a whistle and cover it with almost any color you like.

I’ve used citristrip on a couple frames with great success. Doesn’t require much effort either.

The main point is that there is little to no control over how hot the fire gets.

Or rather, is 350-450 degrees worthy of concern when powdercoating is so regularly accepted as a frame finish?
(Yes, fully aware the OP didn't bake the frame - I read that post. Just thinking out loud).

Which brings up the tantalizing question - what kind of damage can the 350-450 degree Fahrenheit of powdercoating do?

I do sincerely hope the build goes great for you.
Also, I will agree with cb400bill, that original colourway is very nice looking. (Coming from a Marine guy that proudly owns and rides a pearlescent pink Tomassini Prestige😉

Anyone who has thrown a tin can into a campfire knows that a wood fire can get hot enough to seriously deform thin steel. I remember from my wood stove days that wood starts to combusts at about 500f and that the target for a clean fire without visible smoke is around 1,100f. Some air control was generally needed to reach that temperature so I doubt that an open wood fire would get quite that hot very easily.

also a heat gun might be a little more controllable than treating the frame like a marshmallow

Ugghh. Maybe try to find someone a little out of the city. 125 is actually frame and fork in suburban Atlanta. I had an 853 Peloton done for 100.00, no fork, pretty recently, and it came out very nicely.

All this talk about heat damaging steel frames is interesting. Bronze brazed frames are heated up to glowing orange at the joints with no structural issues (proviso that you're using the right tubing that will take the heat, yada yada...) They get reheated in small areas when brazing on tiddly bits (my new favorite term). Tubing properties are designed around construction methods, to some degree, and brazed, steel frames wouldn't be possible to construct if you couldn't heat them up brazing temperatures without damage.
The problem is heat control - any framebuilder will tell you that. If you're throwing a frame into a fire pit, it's hard to tell if small areas get heated up to the point where damage to the frame would occur. Others much more knowledgable in the blue flame arts might chime in here.
However, I wouldn't strip frame paint using heat for a different reason. If you're burning off the paint there could be nasty chemicals coming off that I certainly wouldn't want to breath in.
@Drillium Dude, if your heat gun softens the paint enough, I'd say go for it. I highly doubt that the hot air coming off of them will damage your frame.
