I have a substantial amount of oak flooring that was torn out from a remodel. It is only about 1/4" thick, 2" wide and no tongue and groove, looks allot like lath. It is from the 60's I'm guessing. It has some sort of light finish on one side, more than just stain. I'm guessing either varnish or laquer, just based on the age, definitely not polyurethane. I'd really like to use it as kindling in my tube stove. Terrible idea? Any tips on how to id the finish that's on it?
