I don't know what the "seven stages" of a tempera painting are. What are the seven stages of a 14th century painting? Then, when applying it to the panel, pull the priming brush over the wet gesso a few times to pop out and smooth the tiny bubbles.Īs for painting on bubble-pitted gesso, bubbles cause the most problem when you're using transparent or translucent pigments, which sit in the little pits and show up as more intense specks of the main color. When you make gesso, it helps to mix gently and let it sit for an hour or so before priming with it. The best way is to prevent bubbles from forming in the wet gesso mix in the first place - the only problem is I've never completely managed it. Then let the panel dry, sand shiny, and paint as normal. I have found that a good way to deal with pinholes in the gesso, once they're already there, is to sand the panel with coarse sandpaper until it's really flat (albeit scratched), and then take a sponge or a bit of artists' canvas dipped in water and wrung out, and rub the whole panel in little circles, rewetting the sponge/cloth as needed. Help! I have pinholes in my gesso and they show in the painting. Those might be a better bet for your purposes.
There are, I understand, china paints which are a sort of low-temperature glaze. It doesn't adhere to nonabsorbent grounds, like glazed china, and it's unsuitable for any use which may get wet. I don't think egg tempera is suitable for restoring china. I would be concerned over long-term effects of the extra glues and ingredients, but for practice and playing around, it's not a bad idea.Ĭan you use egg tempera painting when restoring china? I haven't used gouache or watercolors for pigments, but I know people who have and they seem to work. They seem to include a kind of soap to help the pigment stay wet, however, so I am concerned about whether they will last well.Ĭan you use watercolors or gouache paints instead of pigments in water to make egg tempera? There are some art suppliers who provide a limited selection of pigments in water, notably Sinopia. If you keep them wet too long the egg will start to spoil, and if you re-wet them, the egg can spoil, but the paint won't reconstitute.ĭry pigments are so dangerous! Does anybody sell pigments in water already? No, egg temperas cannot be rewetted once they have dried. In fact, egg tempera is noticeably less yellow than oil paint.Ĭan you re-wet and re-use egg tempera paints once they have dried on the palette? The color of the yolk has no effect on the color of the paint, oddly enough. Yes, egg tempera uses the yolk of egg, not the white. * What are the seven stages of a 14th century painting?ĭoes egg tempera really use the yolk? Doesn't that make the paint yellow?
