The pictures above show the before and after shots of a wonderfully colorful and figured bowed psaltery back made of Canarywood. While it’s true that applying just about any type of finish brings out the color and grain in the wood, one of the best finishes for doing this, in my experience, has been Boiled Linseed Oil.

Actually, most linseed oil today isn’t boiled, but it’s instead just some heavy metal driers that help the oil to dry. However, I’m using an all-natural linseed oil that is polymerized—meaning it will dry on its own without the addition of the toxic driers. (Otherwise raw linseed oil tends to stay gummy indefinitely.)

Note that in the second picture, the psaltery still looks a bit “greasy” because I’ve just applied the finish, and I have not yet wiped the excess oil off. The finished surface is actually very low gloss.
