Smoldering Fallout Issue

[Wiley]

So, the problem I was having in July with smoldering fallout is still persisting. This shell is a 2.5" rinfasciatured tiger willow, broken with 2FA. It was spiked once with doubled up 20# hemp twine, well-pasted with wheat paste cooked from flour. Wrapped with 2 turns of 30#, then spiked again with that same pasted twine. The shell was allowed ample time to dry (3 days).

When it broke, there was a heavy concentration of stars coming out in a dense spray, as you can see below. As the stars burned out, a huge chunk of glowing debris dropped out of that dense spray and fell all the way to the ground, where it started a small grass fire that was quickly extinguished. Smaller glowing pieces pelted down in several places afterward, but they self-extinguished on impact.

The big piece of debris turned out to be the top and bottom disks, held together with a strand or two of spiking. All of the casing that was stuck to them had burned away, and was what had made the visible glow as the piece fell. The outer rinfasciature layer and it spiking were still intact and stuck to the disks; it was just the cylindrical part of the casing that had been the fuel for the fire.

Any ideas why this might be happening?

That white streak in the dense cluster of stars is the big piece of debris.

Now it's the little white dot in the left center.

There it goes.

I had that happen a couple times but have since done away with it by "painting" the shell inside and out with a dilute solution of white glue. Makes it more burn resistant. Heres how the remains look now that I do that. Pretty clean considering the fireball they were engulfed in. The one on the left in the first pic is a fresh one just for comparing.

The other pics are of another shell just like it ( the glue shine)but 1 strand. Don't have anything from them since I do like you now with 2 strands. In fact I got that from you
