How to make traditional gesso.
You will need
Rabbit skin glue, gilders whiting (this is chalk, calcium carbonate) a couple of airtight containers, digital scales, a sieve or two, a piece of muslin, a spoon and a brush. A microwave or a bain marie.
This gesso is for antique restoration, not for canvases as it's not flexible and will crack. (For canvasses use acrylic gesso.)

I'm sort of watching two of your shows at the same time here making notes. My job that I just retired from required me to watch ten screens and know what was going on. I'm only doing this to catch up. Normally I try to untrain my brain, I used to get exhausted mentally after 12 hours. So mixing up gesso, the only thing I have to see is if rabbit skin glue is available to me. Thanks again!! The other one I'm watching is for water gilding.

Thanks so much. My name is Manuela Rigano. I was a restorer in the past and now you remind me of a part of my work, which I would like to take back, if only for passion, since now I do a very different job. Just think that now while I see this video of yours just released on you tube I am watching on TV one of the restoration interventions on the frame of a mirror and immediately before another intervention on a fireplace mirror. It's a real refresher lesson :-) But also an integration to what I knew and didn't remember and other things I didn't know, I can't wait to see your other works, thanks again! I kept everything, now I have to go find my agate stone, gold leaf,lacca gum, bolus and all the rest ... I have lost track of it .. :-)

Hope you do get back into restoration. It's so nice to spend time with beautiful objects and work work with natural materials.

@1429376 2 года назад

@@RuthTappinGilder Yes, it is beautiful, and it is also a challenge to find small solutions that are different each time because each time it is never the same as the previous one. And it is also so nice to see an object reborn without affecting its nature and respecting its history, in the case of a conservative restoration or giving new light. You are really good, thanks for sharing.

Supposedly, alum and marble flour were once added. I tried. Thanks to the alum, it doesn't spoil and seems spreads better. Unfortunately, marble flour also needs to be ground in a mortar, but the effect is nice. The substrate is heavier and more durable, but it needs to be sanded.

@backgroundboy Год назад

Thanks so much for all the vids. When using the gesso, can I just keep warming it up to use?

@RuthTappinGilder Год назад

Yes, it may form a skin. If its thin just mix it in if not remove it. You may need to add a bit of water towards the end. as heating can evaporate the water and make it too thick and strong. Hope that helps.

@JckMun 2 месяца назад

I've seen conflicting information about whether you should let the gesso dry between layers (allowing for sanding) or whether it needs to be applied in consecutive layers once it's 'flash dry'. Any clarity would be helpful, as I find doing consecutive layers is messy and obliterates the detail of my frame moulding.

@RuthTappinGilder 2 месяца назад

I like to get all 10 coats on in one day in the summer and a day and a half in the winter. It can cause problems like pin holes if the previous layer is bone dry. If it has dried then just wet it a bit like you would for plastering a wall.

@Marrrrrrrk79 Год назад

I read online that we could skip the gesso and just apply bole. Is this correct? What about burnish sealer? Should we apply that underneath gesso and/or bole? I notice you don’t use it at all. Do you recommend using it only to seal the gold afterwards? Your advice would help! Thank you.

@RuthTappinGilder Год назад

If you're gilding onto wood and don't use the gesso, you will see the wood grain, even through the bole. Gesso is there to give you a smooth surface. I brush on a week rabbit skin glue layer before the gesso. This is like a primer. I would not use burnish sealer at all. Gold doesn't need sealing, only when you use 22ct or lower. then you can seal with shellac.

@lisaghent7748 Год назад

Thank you for posting these videos. I've had many failed gilding exercises so these are really helpful. Just one question, how many layers of gesso do you usually apply?

Hi Ruth, if I could ask one more question: What is your process of sanding the gesso? I saw in your video with the balls that you only used steel wool. I was taught to start from 240grit sandpaper and then to make your way up to 1200! Thank you for your time.

@RuthTappinGilder Год назад

@erinwatkinson6473 5 месяцев назад

My gesso seems right, but dries up in the sealed bowl before I can apply a new coat. I’m not finding the answers as to why in my books. Would you have an idea? My rsg/water is 1:10 and my gesso is 4 parts rsg to 4 parts whiting. I applied a coat, and put the sealed lid onto the bowl, and it dried up in less than 1/2 hour. Was it supposed to go straight into the fridge?

@RuthTappinGilder 5 месяцев назад

Try the resipy in this video. What temperature are you heating the gesso to? that might be a problem. You could be drying it out.I can leave the gesso out of the fridge with the lid on for a day no problem. Anr you making a very small batch of gesso?

@Pepsi_Please 5 месяцев назад

Hi Ruth! I finally finished stripping the million six layers of paint from my frame. What an ordeal. I'm down to the white stuff. The guy at the art supply called me that it's gypsum powder mixed with rabbit skin glue and water. Is that the same as the gilders whiting powder?

@RuthTappinGilder 5 месяцев назад

Gilders whiting is very fine chalk. Gypsum is what plaster is made from. You can make gesso from gypsum but it needs work first. It needs repeated soaking in water to change the ph to neutral. I would go with whiting if you can get it.

@Schnickelg Год назад

Is making gesso putty the same, but just with more whiting?

@RuthTappinGilder Год назад

Less water in the glue and yes more whiting. I'll be doing putty as part of the teaching videos. Hopefully start of next year.

It is water gilding over wood… and that wood is old, and it has some cracks, but i glued them very well… i don’t understand it!! Is there any trick to prevent or avoid thoso cracks from appearing on the surface? Thank you always for your help! Have a nice day!

The gesso will wet the wood. You could try after the rsg gluing adding some natural fabric and rsg gluing that on. Let it dry and then gesso. The fabric can't be synthetic.

@Gallus691 Год назад

Hi Ruth. I was wondering if when making gesso to be used on small pieces with detail you can make a weaker solution of rabbit skin glue? Say 1:10 instead of 1:8. I'm finding that I'm losing detail because of the thickness of the gesso. And thanks for these videos, without you I'd be in the dark.

@RuthTappinGilder Год назад

Glad you like the videos. Unfortunately I would say 70% of my job is sanding the gesso. Sanding is good on flat surfaces, there are gesso cutting tools to get the detail back on wood carving. You have to do minimum 10 coats on wood, other places like compo and plaster you can do less. To thin down the gesso just put in less whiting.

@Gallus691 Год назад

@@RuthTappinGilder Thanks Ruth much appreciated. Another quick question re bole. There doesn't seem to be any yellow, or red on the market at the moment and was only able to get black. I know in the vid re making bole you said you have to start with yellow but due to lack of supply can I just use black in the meantime? I've only found one supplier who has a pot of red but it's 50 pounds and don't feel I'm yet at the stage where I need such a large amount and already made some expensive mistakes.

@RuthTappinGilder Год назад

@@Gallus691 I was using the 3 colours because it's was a Victorian frame and that was the colours they used. So if you're not trying to match a time period or specific country's bole colour then it doesn't really matter. Black isn't the best colour under gold. It will show up any hole in the gilding. But as long as you do the 6 coats needed for burnishing water gilding then the colour doesn't matter. If your not burnishing you can get away with 4 and 2 for oil gilding.

@jakovj.m.5322 9 месяцев назад

According to your experience, does the white chalk have to be specifically calcium carbonate, because according to some claims, everything else is unstable and can have bad consequences on the canvas after a while, or you can freely use any fine chalk, thanks

@RuthTappinGilder 9 месяцев назад

I use the gilders whiting because it's so fine and gives a perfect surface for gilding. Not sure if anything else is as pure or what that would do to a painting. You can use this gesso on a board but it won't flex, so will crack on canvas. You need an acrylic gesso rather than the rabbit skin glue gesso.

@jakovj.m.5322 9 месяцев назад

@@RuthTappinGilder Thank you for your reply, I used ready-made gesso, but I wanted to prepare it myself and I was going to use wood glue, white acrylic paint and some talcum powder like baby powder or corn starch for example.

@erinwatkinson6473 5 месяцев назад

Hahaha I just tried my first batch and I couldn’t have ended up with a more incorrect result. Mine was frothy despite very lightly stirring, and chalky and gritty… so thick it wouldn’t pass through the muslin. My glue was made with the finer US rsg, so perhaps that would have changed the proportion. Then, I don’t think I melted the rsg granules enough fearing I’d go over 140°F. I still can’t explain the frothiness… that happened before I even started to stir! I’m sad but not discouraged. I will research a little more and try again!

@RuthTappinGilder 5 месяцев назад

Not sure whats going on there. Are you using gilders whiting which is the fine ground whiting. You can get much coarser whiting which doesn't make good gesso. It won't go through the muslin when its not warm enough. Get one of those kitchen thermometer so you can see how long uou can heat the glue for.

@erinwatkinson6473 5 месяцев назад

@@RuthTappinGilder thanks so much for the reply. The whiting seemed legit. It’s 100% calcium carbonate by Atlas Preservation. I’m going to reorder different whiting from a gilding supplier. I did use a thermometer, but I thought I was being clever by staying far away from 60°c, but I probably didn’t get it warm enough. The instructions on the gilding supplier website is calling for 5:1 on this finer grade of rsg granules… I’m genuinely not certain if that makes sense, but I’ll give it a shot! This looked so easy! 😆 I will have perfect gesso. Hahaha
