Well, yes. Borates may be non-toxic, but how cleanly do you think a boron fill in this kind of configuration could burn in air?
Think about it! Its completely out of the question !
BTW, the answer to the operative question is: Poorly.
Boron is toxic unless it is fully oxidized. Fully oxidized. Period. Incomplete combustion is *extremely toxic*.
The perfect oxides could be passable for human, but one would have to have criminal intent to try to burn boron in air in a small space.

Elemental boron and borates are non-toxic to humans and animals (approximately similar to table salt).As I said before and will repeat the body count would be extreme !

7 pages in and I can't find anyone saying it's toxic.

In any case, I insist that my methodology -- there is NO chemical which could UNDER ANY CIRCUMSTANCES be used to make a fake -- is correct.
