BLO in shine juice
Sep 8th, 2016 at 6:46pm
 
  I have read that BLO will yellow over time.  When making a "shine juice" is there any substitution for the BLO, or is the yellowing not a problem when used in a "shine juice" mix? Thanks for all the info!!!

Danish oil is 1/3 BLO and tung oil is, well an oil and all oil finishes will yellow over time.

Personally I've always liked the amber color that an oil finish gives.

The first time I saw the recipe for what CEC calls shine juice was when I was in a junior high school wood shop class back in 60s. In essence it is very similar to the french polish that has been around since the 1700's.
French polishing consists of applying many thin coats of shellac dissolved in alcohol using a rubbing pad lubricated with oil

The "shine" is from Elbow grease Grin    More grease in the mix!

Pure tung oil can be very hard to find, BLO is in every woodworking, big box, and most hardware stores.

Tung oil or walnut oil are common substitutes for BLO.

I also made a friction polish by combining shellac ( or lacquer) with a commercial product (Howard's Feed'n Wax) that contains citrus (and other) oils and a blend of waxes.

The basic formula is one part drying oil (preferably BLO, tung oil or walnut oil), one part shellac or lacquer, and one part of the appropriate solvent (DNA with shellac, lacquer thinner with lacquer).

Louie,  I'm going to try the lacquer mix. Sounds like a quick and dirty finish! (In a good way!)

Walnut oil does not seem to yellow as much as BLO, but cures more slowly. The walnut oil I am using is the stuff sold for wood finishes and not the salad oil sold at the health food store. The Mike Meridith or Mike Mahoney variety are not flamable and are shippable. Important as no one stocks that kind of finish here.

Meridith sells a walnut oil based shellac friction polish. 

BLO is cheap, but it continues to slowly darken over time.

It's my understanding that Walnut oil (the edible kind) can be heat treated (polymerized) by simply heating it to just below the smoke point. I believe Tung and Linseed need to be heated in an oxygen free environment, not easy for the average person.
The polymerization helps the oil dry more quickly and adds a better shine.

Any chemists or finishing guru's want to add their input, please do.

I have not tried this yet, but I am planning on an experiment soon.

Most commercial BLO and Tung oils on the market are not polymerized by heat instead they use Cobalt driers which is a chemical.

I have never tried this so I'm only guessing, theoretically you might be able to add cobalt to store bought walnut oil and it should dry.

I knew about Japan driers but wasn't aware that you could purchase cobalt driers (though I never looked)
