Refining Linseed Oil

I have been experimenting with making my own refined linseed oil and walnut oil for painting. I have a small crock-pot full of organic walnut oil. Trying to slowly heat it and not blow up the kitchen. The linseed oil has been washed once with the kids play sand, and salt water. I separated the oil from the water and gook at the bottom of the jar. It is resting now and hopefully will clear up a bit by tomorrow morning because it still looks pretty murky.

The oil in I was trying to clean was mixed three times with salt water and sand. Then three distilled water washes with a small amount of sand. After each mixture I let it sit over night. I siphon off the oil from the top. I let the oil sit open for few days because it looked more like orange juice then oil. The top of the glass now had about 4 ounces of clear oil. The bottom of the glass had some bubbles that might have been water and mucilage. I began with 16 ounces so the yield is not very good. I still do not trust that this oil is clean of mucilage.
