Eric:
Short wave UV might be better than Purple Haze long wave UV.
I won't be able to come to NY for drinks, even fancy-pantsy like
Hendrix, but French nonetheless, drinks. Probably would have to ship
the light anyway, considering the behavior of TSA.

Very interesting Steve. I “thought” petrography would be usefulbut my
problem is that we don’t want to remove any stone and there is
nodamaged area either. Eric:
Make it hard, will you? And this is an exterior facadeexposed to the
rain which might have already washed off any fire soot, or itcould be
contaminated with diesel soot from city traffic.
The surface could be sampled with tape, which would then beexamined.
This wouldn't be as accurate as examining a chip sample of thestone,
but might be adequate. The issues are that not all of the soot willbe
transferred to the tape, and that the soot will be on the sticky side
of thetape under the particles of dust, etc. that transfer to the
tape.
On the other hand, some soot is fluorescent, particularly ifsomething
oily or resinous was burning. Maybe we should just go up to thefacade
at night with my high-power blacklight and look for
streakpatterns above the window vent areas.
