I’ve had this idea kicking around in my head for a few days. I suspect I’m barking up the wrong tree but I wanted to throw it out there and see what others think.
“Boiled” linseed oil isn’t actually boiled. It’s got metallic driers (Japan drier, I think) in it. But I think it’s called boiled linseed oil because at one time it was boiled to get it to cure faster. Such a boiling probably isn’t as effective as metallic driers but there must have been some reason to boil it in the distant past.
Tung oil is also a drying oil, like linseed. I’ve never seen “boiled tung oil” so I’m assuming adding metallic driers to raw tung oil doesn’t help much or has unpleasant side effects.
But…. what about boiling it? I mean actually sticking some raw tung oil in a pot and boiling it? Would that speed up the drying of tung oil?
I’m considering getting a hot plate and a crummy throwaway pot from Goodwill and trying to boil some tung oil. I’m a little concerned about the safety of doing this (I don’t want to start a fire or blow something up).
I’ve no idea how long the oil should be boiled to achieve anything. For all I know it may be a few minutes to a few hours of boiling. Assuming boiling does anything at all.
I am aware that there is “polymerized tung oil.” I believe that polymerizing it does include heating it but I think it it is done under controlled conditions and in an oxygen free environment. It causes the tung oil to act more like a film finish.
What do you folks think? Have I totally lost my mind? Is it an experiment worth doing or will I burn down the neighborhood in the process?
