I have no idea what I am talking about -- zero chemical background --- but it seems the temperature has to be 111 degrees before flammable vapors are produced and I think mineral spirits will ignite at about 400 degrees.
Just don't try it in the kitchen!

I think that, with the small amount of TO I use, that there is no real safety issue. I'm going for it.

Talk to you later, hopefully :-)

If you are in doubt of the safety , one way is to do a flammability test. Throw a match on some of the material . If it goes up in a whoose , don't use anything than can spark , if it just burns nicely I think you are safe. It is the explosive rapid oxidation you need to be careful of.
If we don't hear from you ever again , we know it didn't go well and we will take a collection for flowers

Here's what I did:

Poured a teaspoon or so of TO onto a metal jar lid.
Lit a match - outside, on the back porch - and gracefully tossed the match onto the TO.

After a few moments, there was some smoke, and then a small bit of flame. No 'whoosh' at all, but it will burn slowly.

Opinions?

Dave,
If you start to sand and you hear a "kaboom", then you will know there is a problem.
I can't imagine there is an issue; do it out doors, any vapors will not accumulate to ignite.
However, when I try it (with Shellac), I'm using my pneumatic DA sander. :>)

What is the benefit of sanding while not cured? Are you pore filling?

I use the slurry method to seal and fill the pores.
