Some of the linseed in Tru-Oil and Linspeed is the polymerized type like the stand oil I mentioned. Either oxygenated or cooked or whatever. Alkyds can be added to Linseed to speed the polymerization process. my favorite finishes are a mix of Poly, Alkyd and Oil. I like a little bit of yellowing, the poly adds durability, the alkyd hardness and the oil ease of application and traditional look.

I think all the previous comments were about Tung Oil finish which may not have any Tung Oil whatsoever in it.

The OP is pleased so I will not beat this horse anymore.
