Louis R Velazquez is the man! He should be credited for reviving this method thanks for acknowledging it!
high quality content
Thanks for watching and commenting!
Wow, great video! I’ve bought that book too. Can you make a video while you show the freezer method process?
Fascinating, thanks!
maybe you should become a oil medium manufacturer
Yes!
HELLO AGAIN: Rembrandt’s sun thickened oil was very viscous! He added two STABILIZING ingredients to his oil paint in order to control the excessive flow of his thickened viscous oil. (A) One was Calcium Carbonate powder that is 99% transparent when mixed with oil -and- (B) the second is Egg white Glair . Both create what Dr. Van De Wettering called THIXOTROPY. This means that the oil paint is fluid as long as the artist moves the brush, but when the brush stops moving , the oil paint also STOPS moving. Additionally, the oil paint retains its every brush marks and shape, without slumping, leveling or flowing. NOTE: I have tested the three conditions of the egg; the Clear Glair, the Yolk, and the whole egg scrambled. Of the three , GLAIR is the best because it is sticky ALBUMEN and has NO OIL. The yolk is pure egg oil and it is a very weak oil . The whole egg has the worst and best of both.
Best wishes, Louis R. Velasquez; Calcite Sun Oil . please see my books on Amazon and videos on TH-cam .
The problem with this process for cleaning Flax oil and the further process of "sun thickening" is many people don't live in warm climes. I live in England...I'd say that I'd have to wait for June-Aug to find weather that would be sunny and dry enough , and even then there's no guarantee that it won't rain. I've read the air pump method...I might try that.
Of course You live in Albion....since You are a plantagenant.....😊

What????????
Hello- my recent book’ Rembrandts superior oil and how to make it’, gives my 3 standard CSO methods. Each easy to do (1) the CSO Alcohol psyllium husk method (2) the CSO Air pump method (3) the water freeze method AND for
you in wet cold England is the newest using modern electrical equipment that can cleanse and thicken the oil within 4-9 days
Best wishes
@@portervillelouis I have bought a copy of "Rembrandts superior oil.."...Will get an air pump and give it a go!
All these peeps using name-brand gin, while I'm here crying while I use the cheapest vodka I can find...
Some people in the past used urina to clean raw linseed oil.
@@GEOGigalot That (or ammonia) might be worth a try, I've currently got about 2L finished so I won't be trying that for a while though.
Where do I preorder from? I don’t see a link.

Hello, I live in Germany and don't have a garden as nice as yours, can I buy the oil from Kremer or from them?
Kremer sells genuine Sun thickened oil....but it's expensive.
You can take your initial oil, let air run through it and while it polymerizes it will get crystal clear as well. The initial color is fleeting and is NOT what causes the yellowing. That comes from the fatty acids that polymerize in the oil. Linseed oil has a specific setup, that causes quite a strong yellowing. Mixing it 50/50 with Walnut oil creates a much better mix of these acids, causing a LOT less yellowing. All your processing will not keep your linseed oil from yellowing. Paint a piece of toilet paper with it. Let it dry where you like, even in the sun. Then put it in a drawer for 2-3 Weeks. Observer the paper gets an ugly, strong yellow tint. There is no way to get rid of the yellowing so far. If someone finds it: Please tell us.
this is similar to the Chelsea Classical Studios Lavender scented Linseed oil
Would surgical grade rubbing alcohol work?
I haven’t tried using isopropyl alcohol. It contains denaturants, which smell bad, and may interfere with the mucilage separation process - not sure. Pacheco mixed his linseed oil with a powerful liquor, containing 87% ethanol and 13% water, then mixed it with the buds of lavender flowers. If you try it, let me know how it works out.
@jordinmimran i actually found someone's research and they said isopropyl was stronger so the 70 proof was better used. The research was done by Tad Spurgeon in his book Living Craft. Page is 253.
Thanks for your comment. I’m familiar with the Living Craft book and just looked at page 253. He’s using it in a traditional washing method to remove the mucilage. If you try using a petroleum based isopropyl alcohol in combination with psyllium husk, please let me know how it goes for you… for sure methanol or any alcohol with sugars won’t work well.
@jordinmimran I don't know my chemistry, barely passed over 20 years ago. Isopropyl has 3 carbon atoms, ethyl has 2. What do they bind to? Would I need to halve the amount of alchohol?
@@hookedbycrafting5348 sounds like you’re better at chemistry than me haha! My guess would be to follow the recipe as is (same proportions) but please keep me posted if you try it out :-)
That’s one heck of a lasagna!
Hahaha!
To be honest, I'm surprised that you managed to clean it this way, the alcohol must have evaporated on the first day so it didn't matter anymore. Well, I clean the oil in a bottle. I dilute the alcohol in distilled water to about 70% and shake it, then everything bad falls to the bottom. Sometimes I give some Plantago afra husks, but only a teaspoon, because it swells a lot. But the initial procedure is cleaning in salt water with sand. I will leave the thickening for next season. I was also looking for lead vessels, but it was hard to find anything. BTW, store-bought oil is probably adulterated in some way, with all cleaning process leaving 10%. With local factory oil, about 50% remains.

PORTERVILLELOUIS,SAID:
You are flat wrong with guessing, and misleading others. My 30 year old CSO recipe calls for 6 fluid ounces of common spirit liquor of 80 proof ethanol which is equal to 40% ethanol . Six times this equals 2.40 ounces ethanol. Pacheco used 3 fluid ounces of 174 proof= 87% ethanol ( times 3 equals 2.61 ounces ethanol. Pacheco’s spirit liquor which he called “ agua ardiente de cabeza” ( meaning “ the head” ,was the first part of the distillation and had 87 % ethanol). The second part had much less ethanol and is called “ del medio” ( the middle), and the final portion is called “ la cola” ( the tail) which had much less ethanol “ .
NEITHER the ethanol portion of the spirit liquor -nor- the water portion evaporate as you erroneously claim.
Please read my books and do my tests. The proof is in the pudding

Yours us a failed method, spread for years. Please read my books.

PORTERVILLELOUIS SAID:
You don’t need lead containers for the thickening . Read my latest book” Rembrandts superior oil and how to make it” it will teach you my 4 safe CSO quick methods including one that will cleanse and thicken your oil in 4 days. Peace.
@@portervillelouis "Pacheco’s spirit liquor which he called “ agua ardiente de cabeza” had 87 % ethanol" - really? why not 88,8% ? Alcohol will always evaporate BTW Pacheco distilled the oil in a closed bottle.
PORTERVILLELOUIS SAID:
For the sake of readers who want the truth. Here I give the English translation of Pacheco’s METHOD and RECIPE on how he removed the mucilage from his raw unrefined linseed oil:
PACHECO: ARTE DE LA PINTURA;Su antigüedad y grandezas’ Lib. 2, cup. 9. segundo libro :
ME: The art of Painting ; its antiquity and grandeur ‘ Book 2, Chapter 9 . Second book:
ME: PACHECOS ACTUAL WORDS:
*y aquí añadirémos cómo
se purificará el aceite de linaza para quitarle la amarillez y que sirva al blanco azul.
**Here we will add on how to purify the linseed oil to remove its yellow so it can be used with white,blue
*Tómese una redoma de vidrio
** get a glass flask
*Cómo se purifica
**used to purify
*y á una libra de aceite
de linaza limpio y claro aceite de linaza.
**and to a pound of linseed oil that is clean and clear
( my note: the16th century, European pound measures todays quart. Clear clean Oil means it has had the dirt dust and seed fibers mechanically filtered out- you cannot filter out mucilage mechanically )
*le echen tres onzas de aguardiente fina, que llaman de cabeza,
**add three ounces of high quality spirit liquor that is called “ the head”
( my note: the ‘head’ is the first part of the distillation and has the highest ethanol content).
*y dos onzas de alhucema, ó espliego en grano,
** and two ounces of Lavender flower buds ( my note: you must use actual seed buds and not liquid lavender solvent. The Lavender flowers with the seed buds, are of two main species: one is Espliego ( long flowers with seeds buds ) the other is Alhucema ( short fat flowers with seed buds) both are usable.
*y póngase al sol fuerte quince dias,
**place it in the hot sun fifteen days
*meneándolo dos veces cada dia, ( my note: only the first day must you vigorously shake all contents together - and it must not be shaken again).
** gently swirling it two times a day ( my note: after the first day, do not shake the mixture- only gently swirl it)
*y de esta manera queda claro y purificado,
** in this manner it will be clear and purified
*y colándolo en otro vidrio se pueden aprovechar de él en los blancos, azules y carnes.
** and filtering it into another glass it can be used with whites blues and reds ( my note: I have removed the mucilage using Pacheco’s instructions. The resulting oil is extraordinarily clear once filtered, but the oil will contain Lavender solvent. I wanted CSO not to have any solvents. That led to my discovery of using psyllium husks instead of lavender flower buds. )
END OF PACHECOS INSTRUCTION
I hope readers will better understand Pacheco’s method. I warn all users to wear goggles when looking into the flask . The high potent ethanol mixes with the lavender flowers and creates a powerful vapor that is injurious to the human eyes. I had to go to the hospital because I was not careful. Learn from
My mistakes and learn what my tests have discovered. - best- Louis R Velasquez 3/12/24
