Debunked: Thermite Slag on WTC beams [Oxy Cutting Slag]

During the investigation several pieces of WTC steel were cut up, for example:

This was done with an Oxy-Acetylene torch, seen here:

Note the distinctive slag and rippled surface.

Cutting with an oxy torch makes slag, as it works by oxidizing the steel (burning it away).

This can be cleaned up, it just chips off.

For demolition and quick cuts the line is not always the straightest, and slag production (and cleanup) is not a concern. Metabunk 2018-01-31 12-19-08.jpg

So when you see a beam cut like this, it's not evidence of "thermite" cutting. It's evidence of oxy cutting.
