I have some XS arriving, can't wait. They say you can vape it alone or you can coat your ss Mesh with it.
It has a lower Burn point than the XC[982'C verse 1200'c] but it's still high enough that it shouldn't burn on a E-Cig
This page has the specs. Look for the word silica on the right side to find out the XS Rating.

I plan on trying a Coated SS Mesh setup.
By the way this thread had the temperature of the coils at different colors

So with the XC you are 100% safe with the XS you are probably safe.
