Finished with 720ml of linseed oil and 270ml of fat/mucilage. (About 50ml lost due to spillage.) About 10ml of dubious quality linseed oil is floating on top of the waste jar, which I will discard rather than trying to salvage it. #DIYLinseedOil 🧵14/

And thinking outside the box: While a turkey baster / decanting method does work, I'm thinking that with my next batch I will try using an oil/fat separator cup device because I'm guessing that it likely would work more easily. #DIYLinseedOil 🧵13/

After six washes the linseed oil is separated from the fat/mucilage. Using a turkey baster and decanting between containers it's possible to isolate the pure linseed oil. I've marked the lines in color, green is pure linseed oil, fuchsia is fat/mucilage. #DIYLinseedOil 🧵12/

It is fascinating to see the sand and saltwater sorting out the fat/mucilage from the linseed oil. #DIYLinseedOil 🧵9/

It's a little tedious (and there might be a better way to do it which I haven't figured out yet), but it now becomes possible to suck out the fat and mucilage which is hanging out below the clean linseed oil. Next: Repeat until no more fat and mucilage remain. #DIYLinseedOil 🧵 8/

The sand and saltwater grabs on to the fat and mucilage and falls out, leaving the linseed oil more pure. #DIYLinseedOil 🧵7/

Vigorously shake for about a minute to emulsify. Then let it settle overnight. #DIYLinseedOil 🧵 6/

Put it all in a jar. Shake it hard. Let it settle down overnight. #DIYLinseedOil a thread 🧵 5/

The unrefined flax oil needs to be refined. Flax Seed Oil contains: Oil, fat and gunk. The 'fat' is Omega-3 fatty acids, healthy to eat but bad for paint. The 'gunk' is called mucilage. The linseed 'oil' needs to be refined to be made clean. #DIYLinseedOil a thread 4/
