Thanks to all who have responded with their safety concerns. I
really want to use this thing, because it WORKS, and it cost a
I took a look at the MSDS that was mentioned and I did indeed find
some interesting facts. I'm not sure what "auto-ignition temp."
means, but it's 2200F for titanium in air. Does anyone know the
significance of this?
Also listed is "Extinguishing media", which is either table salt or
a type D extinguisher. If I read this right, a can of Morton's nearby

This really is a fairly thick screen with no exposed points or
extra-vulnerable components. I may even smooth and polish the
section I use most. I'm sweat-soldering heavier silver pieces,
starting with extra-easy solder (so it would be closer in temp. to
easy solder during the final remelting step). I have to keep the
torch moving up and down and all around anyway, so concentrations on
any particular spot would be brief.
If I really am putting myself in significant jeopardy, I will stop
of course. But if I can mitigate the risk I'd like to continue using
it. I'd be willing to cut off a little of it to test heat, if I could
do it safely, and if it would be an accurate predictor of what would
happen heating the much larger screen.
Again, thanks to all of you out there who generously share your
