Purification of linseed oil for Fine Arts - Purificazione olio di lino

The linseed oil unpurified, or unclarified, tends to become more brownish with the years. The clarified linseed oil loses many of its impurities so it remains more transparent than normal oil.
For painting the linseed oil must be purified.
L'olio di lino non purificato, o non chiarificato, tende a diventare più scuro, tendente al marrone, con gli anni. L'olio di lino chiarificato perde molte delle sue impurità per questo rimane più trasparente dell'olio normale.
Per dipingere l'olio di lino dev'essere purificato.

I know that the oil bleaches in the sun but in the dark it returns to its darker color.. I don’t know how Chelsea company purify the oil but it’s so clear and it’s not bleached in the sun so it stays that light color but it’s too expensive..

A separating funnel would make pouring off a lot cleaner/easier.

Can you secure me that this metod 100% works? Ps. I leave oil under mediterranean sun.

[@stephenwhite5444]

What are you adding? I would like to try this but don't know the amounts of what all you did.

[@GnaReffotsirk]

Alcohol mixed with water is also good

[@romulusbuta9318]

For what , exactly ......?

[@EddieEloff]

Sun must be very hot there because my linseed oil did go lighter but only after 4 months. I'm far from clear.

This is the mediterranean sun

Hi.
I am experimenting with linseed oils for wood finishing, cured under uv lights.
I have experimented with adding garlic to the oil. After a year on the sun the oil develops a crust on top and thickens, cures beter under uv light.
What effect does water washing has on the polimerization of the linseed oil.
Do you start with raw oil? Hot pressed or cold pressed?
What about washing the "boiled" (drying agents) linseed oil?

I think just to make the result much purer, clearer, adding no color.
So if we used the purified linseed oil for an Ingredients for a paint/Varnish making, the color appearance is not affected by the oil (the pigments/color tone is totally unaffected)

Hi! Very useful video!!! One question, what´s the type of water? Water from the tap? Distilled from the rain? bottled mineral water for human consumption?
Thanks!

[@PsycoticGoth]

distilled rain water i saw it in a another vids since it avoids the oil from mixing with the minerals and salts in the tap water

[@euricojose3576]

You need a electric hand mixer to blend oil and water, shaking is very slow and poor process. You can use salt and sand in the water.

[@euricojose3576]

@@AlbertGutierrez-pw9kz Thanks! Like sand of a river or the sand of a salty sea?

[@portervillelouis]

Im not a hater- this is a proven faulty method - - sorry. Louis velasquez

[@chrisgriffith1573]

No salts?

[@Adrian_AdamViolonDiGerma-tm3nq]

This proccess is just requiring water and oil.
