Topic tags/keywords: question resource finishing shaker

I was reading a book on Shaker finishes regarding Boiled Linseed Oil. They mentioned how it was thinned with Turpentine and adding 2 tablespoons of vinegar per pint. My question is what is the purpose of adding vinegar to the thinned Boiled Linseed Oil?

Putting vinegar in it makes it a cleaner. Wouldn’t do that unless thats what you want. Turpentine is ok. Thins it and lets it penetrate better

Gary, When you say cleaner, are you referring to removing the color in the Linseed oil?

Not a clue, but my guess is it probably has something to do with the oxidation process that causes the fatty acids in BLO to polymerize, forming the waxy surface.

But that;s just a guess. :S

It could also be a relatively useless addition, or something that has been replaced by newer additives to BLO

For flavor !!!!!!!!!!!!!
Seriously
What I have been told is the “Linseed Oil-Turpentine-Vinegar ” solution was used more as a furniture polish finish, used to enhance the finish that was already there. If you had light sctratches or fingerprints the vinegar (acidic) would disolve them, the linseed oil was the finish, the turpentine was to thin out the oil to penetrate the wood.
On RAW wood you might not need the vinegar is what I am trying to say !

That is interesting. I have always heard of using Mineral Spirits as the appropriate solvent for BLO. My question is, why would you want to thin it. BLO doesn’t build much of a film. It mostly soaks into the pores of the wood and any that I have ever purchased was already pretty thin. However, it is wonderful for returning the life to old wood. Now regarding mixing with Turpentine, you can mix with equal parts of BLO, turpentine and beeswax and you have a wonderful substance for cleaning and bringing any old wood back to life. It is a great wood conditioner. This is the most highly recommended method for cleaning and restoring old wooden hand planes.
