Thank you SOOOOOOO MUCH for this video.!!! Im so glad it's still here. Thank you, thank you, thank you.👍😃

Much appreciate your endeavours, Michael. Myself and colleagues using encaustic medium to make art with (encaustic = 7 parts beeswax, 1 part damar resin) have the problem that we can't use acrylic gesso because it's plastic essentially. Tempera paint used to be an option as a gesso but we understand that manufacturers are using acrylic in this also now. My partner has been making me some gesso from milk and vinegar and lime powder - this seems to be working well - of course - encaustic goes onto a rigid absorbent surface - so cracking is not so much of an issue as it might be on a canvas ground. You sounded a little bit hassled in this video - and tired - I hope you persevere! Nothing worthwhile comes easily :-)

Wow, thank you for all the information, it is very helpful!!! You do a great job!

I'm not a painter, I even can't draw anything, but it's really interesting to watch. Keep it going

Cool man. Thanks a lot.

I empathise with your frustration. I have been struggling with this for years too. Thank you for the explanation. I am wondering if it is possible to make glue from hemp.

Hi. Thanks for sharing your practical experience and theories. I have been looking into the same thing, but for tempera painting, I think that looking at it from that angle might help you as well, because oil and tempera paint has been together on paintings for a long time. I noticed a few differences in the preparing of the canvas (or wood - I am experimenting with very thin 3mm thick ply wood). the differences is that there are three stages, 1: first the glue (protein based, I haven't done much experimenting but from my research I like the casein idea) leave it for 4 to 6 hours for the bicarbonate soda to get the ph right.) paint it on and let it dry completely. 2: whiting (this is were you can use slick plaster of Paris, ground caulk and water, or experiment with rice or corn flour) 3: wetting, how I understand it, there is a shrinkage problem if you leave this stage out. All you do is a wet a sponge (ring it out it mustn't be to wet) and smooth it over your canvas in circles, let it dry, repeat until you have a nice smooth surface... I guess you just need to use your judgement. you spoke about worrying about a smell, the vinegar is meant to help as a preserve against mold and bacteria but it's a good idea to use distilled water as well. The distilling process removes most particles in the water including bacteria. you can buy it from the chemist or use battery water (before it's added to the battery). Good luck. I hope the freeze drying works! here is an interesting link: www.askmaurice.org/casein.html

+Rebecca V Vuuren I appreciate your well thought out and educated comment. I work in a studio as of late, with a mold problem. The mold has touched everywhere but the gesso! The corn or rice flour has been brought up to me before with my friend who helped me with the research. They are Ph neutral and seem to be good fillers. I just haven't tried them yet. I almost abandoned the idea of having the gesso Ph neutral because I can only paint it on wood. There was even talk of using linseed oil with the casein. Rendering the idea for the gesso as canvas gesso; useless. Linseed oil being an acid and all. However linseed oil is actually a wood preserver and wood can take much more of a beating. As far as casein on canvases goes I don't suggest it. Even if it was Ph neutral. You can and it could still turn out well but you would need to keep the canvas very very still. I would even take the time to lay some sizing/gesso on the back to prevent warping and shrinkage. I never had a problem with shrinkage with my plywood. I don't have it with me but I'm sure it was thicker than 3mm. It was 3 sheets thick if that gives you a visual. I was thinking of revisiting this video in the future when I decide to make the casein again. I just need a niche or some more findings. Or the very least write that essay I was talking about in the other video. Thank you rebecca! good luck with your research.

I think that egg tempera would be a lost art if it weren't for a few records like that of Cennino Cennini's "Il Libro dell'Arte". Almost everyone has a take on how things should be done and I have found very little on how to properly prepare the canvas or panel. personally I want to stay as true to traditional techniques as possible without having to rely on commercial products like rabbit skin glue (it's not readily available were I live, honestly neither is pigment).. so that kind of leads me to make my own twists on things. your video has been of great help to me. the shrinkage I was talking about isn't of the canvas (even 3mm wood doesn't shrink, but it can flex) it's that the paint shrinks as the water evaporates... I know with acrylic you shouldn't use more than 30% water or the molecules will be to far apart to bind properly, BUT this is also only really a rule depending on your canvas... for example, it's unnecessary to follow that rule when working on water colour paper because the fibers of the paper will hold the pigment. um, okay sorry if I am babbling, I know you are working with oil; egg tempera is in essence egg based (water solvent) and it was successfully used with oil paint so there might be something to consider there. I get the impression that what you are trying to do is get a very binding but flexible bass coat for your canvas. I think that egg tempera has the most prep-work involved because the paint drys so fast and consists of so many thin layers. maybe you will find your answer (with a modern twist) by revisiting older techniques. Alessandra Kelley would say the stages of a 14th century medieval tempera painting might be: 1. Panel, 2. Glue sizing, 3. Gesso grosso, 4. Gesso sottile, 5. Gilding, 6. Underdrawing/painting, and 7. Painting. it might seem an artificial division, but I think there might be a clue in there if you figure out why there were such steps. It's been rather overwhelming for me... there are so many tiny things to consider and variations. Your idea's ph neutral gesso is new to me, but it makes sense. I make soap (it needs to be ph of 7 or 8 to match human skin) so I understand the importance of ph balance. I did test the casin I made (as the glue sizing - before adding chalk or cornflour or plaster of paris, but after letting it stand with baking soda and distilled water) it had a ph of 6... what ph would you consider acceptable? I don't think that linseed oil would be compatible with the gesso while cooking, but maybe you could use it in the drying process instead of water (if you decide to do a base coat of plain casin and then the casin gesso). you can add a drop of clove oil in for extra protection against mold. infact you can make a spritz for your studio of apple cider vinegar(1/4), water(3/4), clove and tea tree essential oil (5 drops to 10ml) All the best and thank you for letting me brainstorm at you. I hope it helps. :)

WOW! Great experiments.

Actually you don't need a filler or anything at all to paint over casein, casein is supposed to be like rabbit skin glue just one layer or two will do the job to seal the support. The problem is the you need to add saliva to the acid (that just can be even jug lemon) to extract the casein from the milk. Once you have it it's disolved with a base, but you need to add salt also to the mix , so the protein soak more water and you can have a stronger glue, and this need to be boil for some time. Casein was just one of the methods to seal canvas for oil painting, but you can also use starch, wheat flour, honey glue, fig jam, done with this method, which makes very easy to emulsyfied any of these glues with oil, so they could keep longer. Acid only hydrolize a part of the protein the other part needs to be done with saliva witch contains amylase.

Cool, i believe any of these glues were mixed with the honey glue to preserve them better, beside honey was used as a a plastifier. Like in modern watercolors of today.

You need to add some alum to any of these glues, it's very important, it acts as a tanning material. Wheat flour and starch glues are very easy made, sometimes you don't even need the acid, with some alum, saliva and a base like baking soda or similar is enough. Godd luck with the experiments!!

Pronounced Kay-sene. Your confusing the issues. Gesso ground vs Casein ground. Gesso uses hyde glue, and casein uses milk and lime. Do not put the lime in the gesso, you will make plaster! Plaster is totally unacceptable as use for a ground. Casein is a natural binder and the oldest paint known to man. The artist your probably referring to was Van Eyck, and he would have painted on oak panels. A lot of the Russian school used casein grounds. IE Nicolai Fechin. If your glue mixture is too strong, your gesso will be prone to cracking. Slaking is just a process of adding plaster to water, and letting the plaster sit i and be absorbed by the water. Slaking has nothing to do with PH! The cracking (crazing) of the gesso is do to impure water. Use distilled water in all your grounds.

So how would I go about making a Casein ground? Is the ground the same as the paint?

@@finessence808 I am glad your interested, I would recommend you watching the entire playlist that I made on demystifying Jacques Maroger mediums. I give a history overview, then go into various grounds. playlist - kzread.info/dash/bejne/f2eZx5aCXZCWd7w.html Making the Casein ground specifically - kzread.info/dash/bejne/mXlh1K6MZMWyl5M.html "You don't have to use gesso, calcium carbonate. You can use whichever white pigment and fillers you like. The various fillers are mentioned in one of the videos. I have 50 years experience in this, no school will teach you this. I learned from master painters because schools in the 60's and 70's dropped the ball on this sort of education. Good Luck!
