Made in the US by Sinopia, this range of Casein Gessoes are ideal for preparing paper, canvas, plaster, metal and wooden panels for a range of painting and drawing techniques, and can be used directly out of the jar at room temperature. They can be thinned and cleaned up with water.

Apply with a brush or roller in at least two coats and allow to dry overnight before sanding to the required smoothness or burnishing with a soft cloth. If you are using more than two coats of gesso, remember to apply them over a longer time-frame; no more than two coats a day. Because the recipe includes a linseed oil emulsion, it may be advisable to wait four or five days for the surface to cure before proceeding with the artwork.

The recipe for these gessoes includes Water, Calcium Carbonate, Cold Pressed Linseed Oil, Milk Protein (Casein), Natural Tree Resins, Fossilized Sea Shells, Saponified Olive Oil and Salt. The resulting ground is ideal for laying down bole for watergilding or painting in media that requires an absorbent ground, such as Encaustic, Egg Tempera, Borax Casein or Watercolour/Gouache. Once applied and cured, the casein gesso forms a permanent and water-insoluble working ground.

I am runnng an encaustic workshop for beginners. i have bought Sinopia casein gesso to coat 50 small and 12 medium size boards for the students. I need to keep costs down and the Sinopia is cheaper than other dedicated Encaustic gesso and appears to give good coverage with two coats and my trial pieces show it works it is absorbent and the wax holds well.



Creates a lovely velvety surface, that works well for silver point. Could only compare to traditional (rabbit skin glue) gesso. Two attributes to be aware of: 1. it is very delicate/soft, as a result scratches easily. This can be a good and bad thing as you cannot apply much pressure with the metal (which you really shouldn't so) - but then you can use scratching to remove metalpoint marks and go back to the off-white colour of the ground. 2. I found the ground quite water repellent, which makes sense considering it has oil. So it looks totally unsuitable for casein or egg painting or anything water based. I tried casein that after a few days peeled off when paper was bended. Still great results with silverpoint.



Very good perfect to restore wood
