Dude, yer talking in riddles over there...please, plain english. I have no idea what your asking. I just proved why it couldn't have been cut by a clean up worker...BECAUSE I said that black stuff CAN'T be the melted remains of the steel from that column...since the black stuff is obviously a different color than the original steel...which means...if the black stuff can't be molten slag from a torch cut, than a clean up worker couldn't have been the one to make the cut...as a matter of fact...I'm SAYING that black stuff CAN'T BE slag from that column...so no ONE made the cut. THE BLACK stuff is from therma/ite - therma/ite produces it's OWN molten metal...which is in part IRON...which is black like that when cooled off. So, I am saying that therma/ite cut the column...and that black stuff that remains is molten iron that has cooled...molten iron from the therma/ite. THE STEEL from the column HAS NOT BEEN MELTED whatsoever...to imply slag from a torch cut implies the steel from the column has melted.

Look at the front edge of that column....although it's at a slant, you can see that it's clearly without any deformation from molten slag. It's completely unmelted and covered with black iron from the therma/ite.
