Yeah, Troop, I am thinking it is more the atmosphere than the ink. There is so little solids in marker ink that I doubt it would survive 1500F for long.( resisting FC is an entirely different thing). However, I have discovered that the white metal marker pens will stay on through 1900F HT. I mark the tangs of stainless blades with metal type and other info ( or you will never be able to tell one from another), and do stainless HT in batches. I have found that the white pigment just burns off to leave a titanium oxide stencil. It makes it easy to ID the blades after HT ,too.

Stacy, Do you mean the pens with the paint on the inside, that you have to press down on the tip for it to come out?
