Topic tags/keywords: reclaimed cypress log fireplace mantel tung oil finish non-toxic

I have a 5’ section of a reclaimed cypress log that I will be using for a fireplace mantel. The front face is the bark face; I have sanded the top, bottom and sides just to remove roughness and splinters. I want to keep the wood as natural as possible. It was recommended that I use tung oil to seal it, but I’m having difficulty finding pure tung oil. Any recommendations on what to use that will not yellow, has drying properties, will not give off harmful toxic fumes once in use and is safe to use near a gas fireplace? Thank you for any help!!

Pure tung oil would not be my first choice as it will take a LONG time to cure/dry and will offgas odors until it does. That Rockler product may be a “Tung Oil Finish” rather than pure tung oil. If so, it will contain poly, tung or linseed oil, and mineral spirits.
