I had a bottle of pure Tung oil, for about a year in a cupboard in my shop, which is a dry and cool place and obviously protected from both artificial and sunlight.
Today I was going to make some tests and when I picked the bottle it looks as you see. Sometime ago I had noticed it had settled out that white thing on the bottom, but today there are these strange things in suspension which I don't know if are crystals of sort or whatever.
Should I stir it, or rather filter it or throw it away?. I've applied it to a scrap and it looks fine dunno... Any help will be appreciated. Thanks
