Amazing series of painting videos. One of the best I have ever seen. Thank you so much for sharing. It's such a pleasure watching you making the medium by yourself.
Thanks for posting this. I am in the middle of testing several mediums again that I have used over the years and sill enjoy the pull of stand oil, and to a lesser extent, sun thickened. For those who don't know, when you thicken oil it gets more viscous, so when applied , the paint sinks into the medium more and has a tacky quality, which results in drag to the brushwork, pulling more clean lines off each stroke. It will also soften the line just a bit, very hard to see but this can add more realism if you want soft edges. Stand oil will extend drying more than sun thickened, walnut oil is a bit thicker and I feel flows better, takes a little longer to dry. You can add damar varnish and a siccative (dryer, with metallic compounds that speed polymerization of oils) in very small amounts. Right now I am testing 50/50 sun thickened linseed oil plus Liquin (original) which dries in 3-5 days with a high gloss and very smooth finish. As an illustrator, I often used 1/3rd stand oil, damar varnish, turps (or MS) and 10 drops or so of cobalt dryer. This was the classic medium of the Leyendecker brothers and other illustrators who needed their work to dry fast with enough gloss to make it much easier to match skin tones in 2-3 layers. Drys in just a few hours. Using Alkyd paints today for the first layer will also speed things up. As far as adding the yoke (and vinegar to keep it from going rancid, not sure if thats archival) I assume its for thickening the medium. It should already have enough grip and viscosity without the yolk but it will be interesting to test. Thanks again for sharing this info.
Black oil will make fine lines better, and dry quicker. Just heat red lead into linseed and stir until it's very dark. 30% lead ratio is good, but you can play around with it.
Спасибо за ваш труд и полноценные описания технологии. На эту технологию со своими особенностями операюсь (пользуюсь) с 1998 года .Вот одна из линий (направлений)----вместо уксуса свинцовый сахар (свинец(II) уксуснокислый 3-водный) 3-5 грамм на 1 желток вода дистиллированная и общий объем как у Вас
Hi there Mr. Osumu. I’d like to ask you that (1) If I try to use another medium like: Liquin (Newton &Winsor) or Walnut Alkyd Medium (made by M. Graham), is it possible to achieve the same effect you’ve made from the mediums you made in the video? (2) How long to make the sun thickened linseed oil? 1 month or 2 months? And both the mediums are speed-drying medium? (3) Do you use the mediums you made in the video ALL THE TIMES in every step/process of oil painting? Thank you so much
Thank you. (1) I have never compared those mediums with my medium, so I can't say for sure. I think those mediums are probably more solid than my mediums. (2) The time it takes to make Sun thickened linseed oil varies depending on the environment, such as temperature and sunlight. In my garden environment, it can be made in about 2 months in summer. Medium made with Sun thickened linseed oil dries quickly. Medium made with Stand linseed oil dries slower than that. I adjust the drying time by mixing the two mediums according to the drying time I want. (3) I use these mediums at every stage of my painting process.
Yes. When using pure linseed oil, trying to draw a thin line will rather scrape it. For me, this medium is easy to use with free control of the lines. Of course there must be another way to draw fine lines with pure linseed, so I'm not saying that the medium I use is better than pure linseed oil.
Thank you! I guess the vinegar works as a preservative? I mix a little Cobalt siccative into the oil, before I give it to the egg, to make it dry faster. But that makes it toxic.
Thank you xaderp. I don't add a dryer. For me, it dries faster without adding a dryer. I add a medium with stand oil when I want to slow down the drying.
Yes. I like viscous paints. It is effective in creating beautiful textures. The addition of standlinseed oil further increases the viscosity of Lead white.
Sun thickened linseed oil is highly viscous, and if used too much, it will not retain its shape and will flow out. This emulsified medium smoothes the brush strokes and keeps the brush strokes.
When using Sun thickened linseed oil What is the difference between using stand linseed oil? It mainly appears in the drying rate. Stand oil takes longer to dry. I mix the two mediums to match the drying speed I want. If you want to dry slowly, I mix more many stand linseed oil. Another difference between the two is Stand linseed oil is less likely to discolor than Sun thickened linseed oil.
Strictly speaking, this medium is a W/O emulsion. The oil content is very high compared to the water content. And basically how to make this medium is the same as how to make mayonnaise.
@@ruedesilly thank you very much for the reply Osamu. (W/O means water in oil?) I don’t know why mine isn’t working. It looks like mayonnaise but when I try to incorporate into tube oil paint it separates an looks messy. Maybe I messed up somehow.. Do you use only the yolk? I don’t know what I could’ve done wrong. I’m using regular linseed oil (artist grade/cleansed) but not sun thickened..
i made this medium by stand oil and sun oil 。but I don't know how to use them for the right time。can you tell me when to use the right medium?thank you very much!
Oh! You already made them? When using Sun thickened linseed oil What is the difference between using stand linseed oil? It mainly appears in the drying rate. Stand oil takes longer to dry. I mix the two mediums to match the drying speed I want. If you want to dry slowly, I mix more many stand linseed oil. Another difference between the two is Stand linseed oil is less likely to discolor than Sun thickened linseed oil.
@@ruedesilly I was so excited that you answered! Thank you very much! if I use the pure stand oil ,mix it in the white to paint the underlying The surface of painting will be very smooth.Will it affect the back cover dyeing if I use the medium? Or rather,you mix the white with pure stand oil ?or the medium ? If I use the medium to paint the underlying,when it drying,Can I use the same medium for the “ cover dyeing “?
Egg oil emulsion is great, but i think you can do the same or better if you actuallly use only linseed oil that was also beaten with some calcium carbonate. Beating using a whisk introduce air to the egg or oil.
@@mithatkorler7070 I understand. I rarely experience such “beading up problems”, but I think that if the lower layer is high in oil and the lower layer is very dry, it will often repel the upper layer. In that case, you can prevent it from repelling by applying a certain amount of turpentine to the surface to activate the surface and then applying paint. Of course, it is important to first consider the principle of ”fat over lean” in oil painting.
It can be stored at room temperature for more than 3 months. It rarely rots. However, if stored for too long, the medium will gradually undergo oxidative polymerization in the syringe and solidify.
It does not rot when stored at room temperature. I use it for 2 to 3 months. If left for too long, the oxygen contained in the medium will cause oxidative polymerization to proceed and the medium will begin to solidify.
@@ruedesilly I see, Thank you for clarifying! Does the type of vinegar change the proportion? Some vinegars have higher pH lvls which make them really acidic, and I was curious if that is something to be concerned about. Thank you for the wonderful content :)
It does not need to be stored in the refrigerator for anti-corruption purposes. However, storage at low temperatures may have some effect on slowing the rate of oxidative polymerization in the syringe. In that sense, the effect of extending the life of the medium may be slight, but it is possible.
Hi Maestro! Thank you for explaining of this medium! I want to ask something about uses of this medium with White color for underpainting. I use it with Titanium White but when it dries the paint cracks! Can you tell me why? Thank You!
I use this medium in every color, but I have never cracked it. Is the medium you made the same as my method? And is it well emulsified? Is it not separated from water and oil?
Hello Mr. Osamu!! This is very helpful!! Did 15th century artists like Van der Weyden and Jan van Eyck use this medium?? If they use this, at what stages of painting? And second question pleaseee!! Have you studied about their mediums, did they use water-soluble tempera or they use turpentine to thin their oil or emulation paints. Please answer, this is very very important to me!! Thank you in advance 🙏
Start with linseed oil, mix using a blender linseed oil, vinegar and some calcium carbonate, then cook this oil in a saintless steel pan at medium fire for 45 minutes, let cold down and save the oil in a transparent bottle, put that at the windows to bleach. Cut with turps or MS for using as a medium.
Mr. Osamu, I made this medium following your recipe, but I used Stand Oil instead of the oil thickened in the sun, but mine was liquid and not pasty like yours. Is it because of the vinegar I used?? Or did I hit it for a little while? Thank you very much for all the lessons!
It can also be made with stand linseed oil. By the way, the process often fails if you are not used to it. For example, if you do not add oil little by little, water and oil will easily separate. Also, even if the amount of oil is small or large, it will not become a paste. It requires some experience. Find out how to make mayonnaise. I think it will be very helpful in making this medium.
The fact that you are willing to share that…..you are more generous than the teachers I had in art school . Thank you.
Exactly.

卵黄1個にお酢は大さじで何杯位でしょうか？
サンシックンドオイルは市販のものでも大丈夫ですか？
ビデオの中で説明しているのですが、卵黄1つ（約20cc)に対し約５～６倍程度の油です。入れながら硬さを見て一番硬くなったところで止める感じですね。それ以上入れると一気にかたちを保たなくなりますので注意が必要です。もちろん市販の油で大丈夫です。
卵黄の５〜６倍なんですね。もう一度やってみます。ありがとうございます。
You are the best. I enjoy your videos so much... Thank you.
This is amazing video!!!!! For how long you can store it????

Thank you for this!.. what kind of Vinigar should one use? Vinigar Essence or is normal White Vinigar alright to use?
Thank you very much for sharing. what kind of vinegar do you use?
can you please tell me why you add the vinegar? Thank you for sharing this medium
vielen Dank für die Einblicke, es ist sehr interessant
I learned so much from this!
Suggestion: When making egg tempra i use the best half of the egg shell as the measuring cup. Try breaking the egg shell in a clean edge half.
What kind of white vinegar do you used in the process of making tempera, sensei? Can i use white vinegar for cooking?
Great demo! I guess in pure oil it's easier to scratch out the finer lines with the end of the brush handle or a toothpick rather than painting them.
Yes. When using pure linseed oil, trying to draw a thin line will rather scrape it. For me, this medium is easy to use with free control of the lines.
Of course there must be another way to draw fine lines with pure linseed, so I'm not saying that the medium I use is better than pure linseed oil.

Is anything added to the white paint in these tests to make it flow off the brush like that?
Yes. I like viscous paints.
It is effective in creating beautiful textures.
The addition of standlinseed oil further increases the viscosity of Lead white.
Hello Master, how long does the medium that you prepared have to live and having in the fridge extends its life time more?
does it yellows and cracks in time?
what kind of benefits do vinegar and egg yolk bring to sun thickened linseed oils structure into a medium ?
Sun thickened linseed oil is highly viscous, and if used too much, it will not retain its shape and will flow out. This emulsified medium smoothes the brush strokes and keeps the brush strokes.
@@ruedesilly thank you for explanation Mr. Obi. Best regards.
Mr. Osamu, from where did you find this medium recipe?? Is this invented by you??
Thank you Levon Avagyan. This may be the answer to your question. www.osamu-obi.com/rembrandts-medium/
What was better for useability between sun-thinkend linseed + egg-youk and standoil + eggyolk?

It mainly appears in the drying rate.
Stand oil takes longer to dry.
I mix the two mediums to match the drying speed I want. If you want to dry slowly, I mix more many stand linseed oil.

Stand linseed oil is less likely to discolor than Sun thickened linseed oil.
I tried to make this just a couple hours ago but it seems to brake and not be working..
Maybe u accidentally made it an oil in water emulsion ??

How do you deal with beading up problem Mr. Obi? When I use that much thick oily medium my upper layers dont stick to lower layers.
What is “beading up problem”?
Does that mean the paint repels?
@@ruedesilly yes . Sometimes new layer doesnt stick to previous oily layers.
