Linseed Oil Bleaching

Linseed Oil Bleaching

I’ve been researching linseed oil, and discovered the SRO method by Tad Spurgeon.  I also was surprised to see that linseed oil can be bleached separately from thickening.

The results speak for themselves.  The picture above (with the coffee stirrer) is 18 months of exposure to sunlight in the window.  It was covered during this time.  No appreciable thicking has occurred.  Up to 12 months slight lightening had occurred, but after 12 months the bleaching accelerated rapidly with very clear oil achieved at 18 months.  This oil was in a fairly sheltered window with little direct sunlight and in a northern latitude.

Next, I’ll be testing out the oil to determine the yellowing properties when dried.  Stay tuned.

Let me know what you think...
