Alright, I'll stab at it.
I'll throw some info out there for anyone to consider.


"Drywall is composed of 92% gypsum (calcium sulfate dihydrate CaSO4 2H2O)"

"Incineration of drywall is also a poor disposal option because the
sulfate present in gypsum is converted to sulfur dioxide gas. Sulfur dioxide gas reduces the
alkaline scrubbers ability to remove other acidic gases."

When powdered, it will burn at...(reference needed).


Sulfur dioxide, the easy definition :
"Inorganic compound, heavy, colourless, poisonous gas (SO2). It has a pungent, irritating odour (the smell of a just-struck match). It occurs in volcanic gases and dissolved in the waters of some warm springs. Huge quantities are made industrially for use as a bleach, as a reducing agent, and as sulfites, which are food preservatives. It is a precursor of the trioxide (SO3), used to make sulfuric acid. Sulfur dioxide is formed when sulfur-containing fuels are burned; in the atmosphere it can combine with water vapour to form sulfuric acid, a major component of acid rain."

Bleach will easily rust bare steel. I use bleach at my job to do just that....make new steel look old.... literally in minutes.

Huge quantities of drywall dust were at GZ, as were heat and fire.
But the question remains is, was it able to transform into sulfur dioxide in sufficient quantities to corrode holes in steel.
Don't dismiss this too fast, as all the necessary ingredients were present.
Glancing at many wikipatents, it doesn't seem too un-probable that "elemental sulfur" in trace amount could have resulted from the wild mixture of compounds, fire, and water/steam found at GZ.

Oh, and there was salt water being pumped from Hudson Bay to dowse the fires for over a week.

post 204 suggests that the beam melted prior to collapse, which would rule out any magical processess in the rubble pile causing the melting and thinning of thick structural I-beams, including the formation of holes like "swiss cheese" which looked like parts of the steel had "vapourised".

sulphur dioxide is not elemental sulphur, it is a gas and disperses in air, disperses much faster in hot air I would suggest. Any interaction with water is likely to produce a very weak acid certainly not capable of dissolving its way through 1-inch steel I-beams like blood from a sigourney weaver alien.

You mention bleach, not sure what the relevance is.

No the question does not remain, sulfur dioxide does not melt or vapourise structural steel.
