Have you ever looked at a floor in a room where an oxyacetylene torch was used? You will find A LOT of near perfect spheres, mostly hollow.

Nice try.
I think my logic worked just fine for me.

Do you know that burning steel wool produces a thermitic reaction?
How do you figure the temperature is reached to produce the tiny
sphere balls. Steel wool even burns when it's wet providing a chemical
reaction, NOT combustion.
Your logic is terrible. Your example is terrible.
so stated to HEAT, not BURN the IRON.

I'm ready to call your bluff Pteridine! Your excuses don't even make
sense! "The spheres are not iron", "the spheres contain iron because of the red chips contain iron"...
If that's true, why is the red chip still intact in this photo? I thought it
would have reduced itself into a sphere?

So, let's do the experiment. You are telling us that heating up paint
that is applied to iron will form spheres at 430 degrees?
We can do this a few ways. Using an oven; using a gas burner, or using a
fire pit.
I have a pan, video camera, some paint, thermo-couples and even a high
power scope which I can use in my lab at work.
I can obtain iron chips, and/or iron oxide. I can even paint the grill in my
fire pit.
I'll monitor temperature of the sample, ambient and heat source all at once in real time.
I'll video tape the entire process.
I'll repeat the experiment in the firepit, on an open burner using a pan,
and in the oven using a pan.
I will photograph and magnify images of the sample before and after
heating in each scenario.
We'll see if ANY sort of sphere forms.
Are you up for the challenge and face the errors in your understanding of
this topic?
Do you have anything to add before this experiment begins?
Methods? Criteria? Suggested observations? Suggested materials?

Well if I were to speculate on how they were used I'm not so sure they would have been used for cutting anything. I would think it would have been for some other purpose as they may have suggested it was an igniter of some kind. I know Jones said he estimated 10 tons of this stuff. I believe I read he also estimated 10 tons when he was talking about the spheres in the dust (I'm going by memory here but I'll look for the link), before he found the red chips, so that's odd... he said the same amount before finding the chips. He's probably just blah, blah, blahing about that. I'll wait until he releases how he comes up with that to see about that.
What really got me interested in this was this paper:
e-reports-ext.llnl.gov...
In it it talks about Iron - Aluminum - Silicon reactions and it states:
"The goal of this work is to examine the influence of SiO2 on the energy release properties of the Fe2O3–Al thermite reaction."
"The presence of Si02 are more insulative than the highly conductive properties of Fe203. For example, the thermal conductivity for Fe2O3 is 20.0 W/m K and for SiO2 is 1.38 W/m K [12]. The presence of SiO2 hinders flame propagation by behaving as a thermal heat sink and resisting the transport of heat through the mixture, thereby reducing the velocity. Although SiO2 contributes to the chemical energy generated, adding SiO2 reduces the overall speed of the reaction by inhibiting thermal transport and reducing the combustion temperature."
We talk about just the Iron Oxide/Aluminum thermite but there was also silcon in the chips so it's harder to figure exactly what this is. BUt it's easier to just use the Iron Oxide/Aluminum example, as I can't find anything about Iron Oxide/Aluminum/Silicon reactions.
So the point I'm trying to make is if these were used it may have been for a more controlled purpose than just cutting through steel.
Edited because I'm sure I should be I'm

The flame is not intended to melt the metal, but to bring it to its ignition temperature.

" #3. Grab your video camera and heat a chip of iron to its melting point
temperature. Show me the solidified (once molten) iron in the form of a SPHERE.
I'll be waiting. "
That is what you asked for .
Once again , I can take the torch and direct the flame onto the steel , and heat it to the point that it will drip , WITHOUT cutting it .
Can't prove that. What we are saying is that molten steel will tend to cool BELOW it's melting point temperature while it is falling down through the cooler air that surrounds it.

Prove it to me, and everyone else: The same drip of iron that you say
will form a ball when hitting the ground at melting point temperature.
