|PLEASE SCROLL BELOW TO LEARN ABOUT THE NEW MUCILAGE
REMOVAL METHOD I CREATED IN 2018 -
THE " CSO PSYLLIUM HUSK-WATER METHOD"
THESE ARE THE TWO CURRENT CSO METHODS OF MUCILAGE REMOVAL
both are fully described in my books
1. The 'CSO PSYLLIUM HUSK - ALCOHOL METHOD'.
This is the method I based on Pacheco's method of 1649. It uses strong alcoholic liquor of 87% Ethanol. I discovered and
pioneered the use of Psyllium Husk for use of mucilage removal from unrefined flax-linseed oil.
It takes 10 days to remove the mucilage.
Instructions are on page 38 of my book Volume 1: Oil Painting Lessons with Rembrandt and Calcite Sun Oil
2. The 'CSO PSYLLIUM HUSK ( Velasquez-Tavenier ) AIR PUMP METHOD'.
An alcohol free method created by Daniel Tavenier ( of The Netherlands) and myself in April 2015.
It is the simplest method of the three and removes the mucilage within 24 to 36 hours.
Full instructions are in Volume 2: Oil Painting Lessons with Rembrandt and Calcite Sun Oil

THIS PREMIUM OIL IS NOT RECOMMENDED FOR FINE ART OIL PAINTING
BECAUSE THEIR "PURIFIED LINSEED OIL FAILED THE WATER SEDIMENT TEST - see
THIS FINE OIL IS MADE FOR PAINTING WOOD HOUSES - TO STOP THE DECAY FROM
Swedish , Allback linseed oil, is sold in the USA by ….http://www.solventfreepaint.com ... but manufactured and processed by the
Allback company of Sweden.
I have read their website carefully several times, and I have written to them for specific information.
Swedish words translated into English, as in all language translations, lose some meaning.
Example; Their website says that if linseed oil is not first purified, but is BOILED to a certain temperature, it will EXPLODE. ......Well, that’
s not true.
But, it will IGNITE. It is not that they are misleading us, just that the translation is weak.
I was able to understand the basic information their website says about their oil by applying common sense and use of my experience.
The one important question I have asked Allback, is this; ‘ What is the maximum temperature your PURIFIED oil…not your BOILED oil ---
is heated to.
This very important question is based on my research of scientific academic sources that states flax/linseed oil begins to decompose
at 230-236 degrees centigrade.
The allback company has never responded to my letters. The USA representative did respond after two letters, and would only say
that the process is patented, and they will not divulge it. This reluctance to inform the public is not helpful to us artists. My patent in the
USA is open to the public, so I do not understand the reluctance.
PLEASE KEEP THE DECOMPOSITION TEMPERATURE IN MIND AS YOU READ THIS
This information is from academic sources and is on my website:
200 Degrees Centigrade = The Old Masters use of a goose quill to indicate SAFE heating
230-236 Degrees Centigrade = DECOMPOSITION BEGINS / Carbonization/ Reduced Lifespan
300 Degrees Centigrade = Modern Stand Oil - heated/ without Oxygen
300 Degrees Centigrade = Oil smokes and produces TOXIC Carbon Monoxide and Acrolein gas
343 Degrees Centigrade + = Oil begins to BOIL
343 Degrees Centigrade + = Oil Ignites / Catches fire
380 - 425 Degrees Centigrade= Burnt Plate Oil made by modern testing
Some websites recommend use of Burnt Plate Oil.
BURNT PLATE OIL is a very decomposed oil meant for disposable Lithography. Its true name is ‘
Rembrandt's etching were made with Lithography Oil, and they are kept under wraps, covered, in
the shade as much as possible.
The Allback website states they process and sell two kinds of linseed oil. BOILED and PURIFIED.
1. ALLBACK'S " BOILED" linseed oil.
Swedish Flax oil is undoubtedly one of the highest quality oil GROWN and HARVESTED in the world. But the processing of the RAW OIL
determines the FINAL QUALITY for the needs of artists. This Allback oil is BOILED and they do not deny it. They in fact are very proud of
it, as they should be. Because its high quality BOILED OIL is made for painting houses and fences and all manner of wooden objects ,
AND... they NEVER advertise it for fine art oil painting. Linseed/ flax oil begins to BOIL at 343 degrees centigrade. This is far above the
safe temperature of 230-236 degrees centigrade at which time the oil begins decomposition. What does ’
decomposition’ mean in terms of artists oil? This: For house painting, 50 years is an adequate life span, and no one expects more. Of
course the house is blasted by rain, sleet, sun and snow. It’s a miracle it lasts 50 years.
A Van Eyck painting left to those outrageous conditions would not fare any better. The key here is that by BOILING the oil, and causing
its decomposition, its lifespan is severely compromised. But given that its service is - 50 years, it’s a moot point. I would bet my money
that if the house was painted with Allback BOILED oil, and kept indoors next to the Van Eyck painting for 600 years, it would not come
close to the state of preservation of the Van Eyck painting.
CONCLUSION ON ALLBACK'S BOILED LINSEED OIL: : DO NOT use any BOILED linseed oil for fine art oil
painting regardless on who makes it
Science says it is severely decomposed with a shortened life span.
2 . ALLBACK'S " PURIFIED linseed oil".
a. = The oil is pressed COLD. This is GOOD. Cold Pressed oil is great, but even gentle heat in pressing is allowable as this oil is very
b. = Then it is stored and allowed to stand still. This is GOOD too , because this means it is allowed to settle the vegetable particulate
caused by the pressing of the seeds. When freshly pressed it is FULL of husk, dirt, and other sediment. Gravity will allow this heavier
particulate to settle.
c. = Then the top clear oil is siphoned off. This is GOOD. Because now the clear oil is easier to be further processed. Allback, just as
the Old Masters, learned something very important. NO AMOUNT of gravity will remove the MUCILAGE. Mucilage is a very complex
ingredient. Nature placed it inside the seed for reasons of nurturing the rebirth of the seed when it is sown into the ground. Mucilage is
INVISIBLE to the naked human eye. If you looked at a WARM glass of that clear bright top oil siphoned off the top, it would sparkle with
great beauty of transparency. BUT, it is filled with MUCILAGE. The Old Masters learned of this over centuries of oral tradition. Mucilage
will ferment, decompose, and turn the oil paint made with it, BROWN and DARK, if not removed. The Old Masters knew this and tried
everything under the sun to remove it. Some succeeded and the evidence is their 600 year old oil paintings with colors that remain
jewel-like. After the Old Masters’ demise, 19th century scholars like Eastlake, followed by many generations of other artists, all tried
their hand at cleansing the oil. Finally, industry cleansed it with caustic lye chemicals, but ruined the oil’s durability, and properties, in
d. = Then, the Allback website says, the oil is ‘heated gently’ to remove the PROTEIN while it is exposed to OXYGEN. This oxygen
procedure is not explained. But, I can add my personal knowledge here. Since I have worked with the cleansing of the oil for 4 years
now. The goal is to remove the Mucilage and by heating the oil, the heat thins the oil. This certainly helps but it is not enough. Exposure
to oxygen, especially if HEAT is being applied, is very necessary, or, the steam water vapors remain in the oil, causing and
perpetuating moisture retention and slow drying. Since Allback wants a faster drying oil, oxygen is part of the process. The Old
Masters knew this too, that the oil must be left uncovered as it is being sun thickened.
It is interesting that Allback calls the MUCILAGE, by the term, PROTEIN. Some call it BREAK, and, others call it the ‘FOOTS”. Regardless,
the Allback website says it treats the oil with several gentle heatings and does their very best to remove ALL the PROTEIN, as they call
it. Only then, do they call this oil PURIFIED.
CONCLUSION ON ALLBACK'S PURIFIED LINSEED OIL. : Since I know the oil begins decomposition at 230 degrees
centigrade, If I knew the temperature the Allback PURIFIED oil is heated to, I could make an informed accurate decision. Llacking that,
I cannot endorse Allback oil for fine art oil painting.
Some artists are either unaware of the decomposition temperature of oil or do not care.
TESTS OF ALLBACK HOUSE
PAINTING LINSEED OIL
The tests were started on 5/1/09 and
ON 6/23/09 I placed all samples in a box
without any light.
On 9/16/09, I removed the samples and
took photos of each. This almost 3
month standing in darkness produced
the following results.
#10= The ALLBACK BOILED LINSEED
OIL fared the worst of all samples. A
thick white concentration of mucilage
sits on the water under the oil.
#6 = The ALLBACK PURIFIED
LINSEED OIL, recommended by some
websites. It fared almost as bad as the
BOILED sample. PURE white mucilage
rests on the water.
|WATER TESTS TO
SHOW MUCILAGE IN OIL
These series of tests below,
show the results of 1/4 inch of oil
resting on 2 ounces of water,
over several days.
The white paper resting beneath
the jars has 2 lines. a solid black
and a red.
WATER IS POLAR AND DRAWS
DOWNWARDS LIKE A MAGNET.
The Old Masters found out that
oil standing on water ,
regardless of how long it is left
will NOT remove all the mucilage
from the raw oil.
|THE MAGIC OF PSYLLIUM HUSK
THERE DOES NOT EXIST ....IN ANY ANCIENT TREATISE NOR
IN ANY MODERN TEXT ....ANY MENTION OF PSYLLIUM
HUSK AS AN INGREDIENT TO REMOVE THE MUCILAGE
FROM THE UNREFINED FLAX LINSEED OIL. Psyllium husk
was completely unknown to all the Old Masters , and
remained unknown to all subsequent theorists, artists ,
conservators and writers, including the artist-theorists of
THIS IS HOW I DISCOVERED THE USE OF PSYLLIUM
HUSK FOR REMOVAL OF THE MUCILAGE FROM
My doctor recommended I drink Metamusil for
irregularity. Metamusil is the brand name for a high fiber
laxative and it is pure Psyllium Husk. One teaspoon in an
8 ounce glass of water quickly expands to four times it's
size because it absorbs the water. This gave me the idea
to use it as a " mucilage remover" because mucilage is an
aqueous ingredient . To our benefit, It worked!
PSYLLIUM HUSK -- AS THE MUCILAGE REMOVER--began a
revolution in removing the mucilage from the unrefined
THE SECOND REVOLUTION was made possible by the
common acquarium electricsl Air Pump. It accelerated the
mucilage removal, taking less time.

MY WORK TO REMOVE THE MUCILAGE FROM THE UNREFINED OIL
In the beginning, I focused on improving the successful 17th century recipe by Francisco Pacheco, published in 1649.
Pacheco, was the teacher of the great Spanish painter, Velazquez. Judging by Velazquez well preserved paintings, Pacheco's recipe has
proven to be archival.
The importance of mucilage removal - was well known to all the Old Masters for over a thousand years. Numerous recipes exist in ancient
texts, of methods intended to remove the mucilage. Most do not work, and for various reasons- the least effective is the "water washing"
in the 1600's, Pacheco solved the " water washing" method, and he did it by using a liquor high in ethanol ( 87% ).
His recipe contained very little water for cleansing 16 fluid ounces of oil ( approximately 1/3 fluid ounce of water).
Pacheco knew nothing of Psyllium Husk and its powerful ability to absorb water.
BY A QUIRK OF FATE, I discovered PSYLLIUM HUSK for efficient removal of the mucilage.
This water absorbing material has proven to be indispensible for mucilage removal.
It is now is used in all three of my CSO oil cleansing methods.
THE 'CSO PSYLLIUM HUSK- ALCOHOL METHOD'
For many years, I was content with my modern CSO PSYLLIUM HUSK- ALCOHOL method , which I based on Pacheco's 1649 recipe.
I eliminated Pacheco's use of Lavender flower buds - and replaced it with Psyllium Husk . My method was efficient, easy to do,
and resulted in a "solvent-free oil". Pacheco's oil contained Spike solvent which was excreted from the lavender flower buds by the ethanol.
A REQUEST FOR A NON-ALCOHOL METHOD
As years passed, I received numerous inquiries from artists around the globe, basically complaining that alcoholic liquor was prohibitively
expensive in their countries. From early 2014, to early 2016, I began testing and searching for a "non-alcoholic" way to remove the mucilage.
I enlisted the help of some fine artists I had met via my website. I must acknowledge them because their concerns and hopes inspired me to
break out of my passivity. Without their help, suggestions and ideas, the new non-alcohol methods of mucilage removal would not exist.
THE AIR PUMP ( Use of this new apparatus was first posted here in 2012 then in 2015 )
During this period, a difficult problem persisted that needed to be solved. This was related to the fantastic development of using an
aquarium air pump to thicken the oil so it would be a faster drying oil. The problem with the " Air Pump" method was that it was useless if the
air was humid. Artists in wet humid northern areas, or artists in hot muggy humid areas like Florida, could not use it because the air pump
would pump moisture from the humid air, into the oil. This created a very slow drying oil. I had no solution to the problem except to tell artists
to use it only in areas with dry air.
In April 2015 , my friend Daniel Tavenier , a resident of The Netherlands,
conceived of a new idea to absorb any moist air pumped into the oil jar by the air pump. He theorized adding some dry Psyllium Husk to the
oil jar containing the previously CLEANSED oil. His theory was that if any moisture was pumped into the oil jar, by the air pump, the husk
would absorb it. It was a brilliant idea!
Daniel's idea inspired me to wonder whether the UNCLEAN oil ..could possibly be CLEANSED of mucilage by adding Psyllium Husk and using
the air pump together. On April 19, 2015, I conducted two concurrent 24 hour tests , one with dampened husk and the other with dry husk.
After 24 hours passed, the oil was filtered and tested for cleanliness. The test using dry psyllium husk proved to be effective and the test
using damp psyllium husk failed. My photographs show the results. The new method is named the "CSO Psyllium Husk (Velasquez- Tavenier)
Method", in recognition of Daniel's original idea.
The "CSO PSYLLIUM HUSK-AIR PUMP (Velasquez-Tavenier) METHOD"
is a NON-ALCOHOL, mucilage removal method of historical importance . It was developed jointly with my friend, Daniel Tavenier, a master
artist and master teacher, resident of The Netherlands. For years my own research has been to produce the finest Flax seed oil for oil
painters. To do this, I had to find a safe and efficient way to remove the mucilage from the unrefined, food grade, cold pressed flax seed oil.
The very same high quality oil the Old Masters had.

“THE CSO PSYLLIUM HUSK- WATER METHOD”
THIS METHOD REQUIRES A CRUCIAL SECOND STEP , TO BE FULLY EFFECTIVE
RECIPE: “ CSO Psyllium Husk - Water method”.
PART ONE : PROCEDURE:
PART TWO= CRUCIAL STEP
THIS METHOD REQUIRES A CRUCIAL SECOND CLEANSING TO BE FULLY EFFECTIVE
PART THREE: TESTING THE CLEANLINESS
To test that the oil is cleansed and contains no mucilage, place the lid tightly and place the jar in the refrigerator. Leave it there for 2 to 3 hours. Clean,
mucilage-free oil will remain crystal clear and fully transparent in the cold refrigerator no matter how many hours it remains. HOWEVER, Do not leave the
oil jar in the refrigerator longer than needed because moisture condenses inside the jar. A mucilage free oil will remain beautifully transparent over the
years. One drop rubbed onto a white ceramic plate shows the oil has no yellow color.
All jars of linseed oil, whether cleansed oil or oil containing mucilage, will be completely transparent in hot temperatures. Oil that has not been cleansed
will become hazy and cloudy when it remains in the refrigerator for many hours.
A cleansed mucilage-free oil will remain crystal clear , 100% transparent in the cold refrigerator.
Different producers of unrefined, raw, flax/ linseed oil produce oil with varying amounts of mucilage. Some oils are more clear or more cloudy than others
when in the cold. Their Quality control is a difficult issue.

FRANCISCO PACHECO : VELAZQUEZ' TEACHER
THE SEARCH FOR PERFECTION
Even though an Old Master once wrote that it is not possible to remove 100% of the mucilage, I have never stopped seeking a method that will
remove 100% of the mucilage
from the Flax-Linseed oil. However, there are too many uncontrollable variable factors that interfere with this goal becoming a reality. Even my
tests of modern Alkali Refined linseed oil bought at any Art supply store, have detected some degree of mucilage in that modern product.
My original CSO method of removing the mucilage
was based on the 17th century method of Francisco Pacheco ( published in 1649).
As you know, Pacheco was the teacher of Spain's great painter Diego Velazquez.
Here is Pacheco's method, word for word, as published and written in Spanish:
LIBRO TERCERO, CAP. V:
“Tomese una redoma de vidrio - y a una libra de aceite de linaza limpio y claro se le echan tres onzas de aguardiente fina, que llaman de
cabeza, y dos onzas de alhucema, o espliego , en grano, y póngase al sol fuerte quience días, meneándolo dos veces cada dia, y de esta
manera queda claro y purificado, y colándolo en otro vidrio …".
BOOK THREE, CHAPTER FIVE
“Take a glass flask – and to a pound of linseed oil that is clean and clear, add to it three ounces of fine quality liquor spirits, that is called ‘from
the head’, and two ounces of Lavender, in seed, and place it in very strong hot sun for fifteen days, swirling it two times each day, and by this
method, it will become clear and purified, and filter it into another glass..”
