Portrait painting tutorial Part 3: Colour glazing

Part three in a series of tutorials on how I apply a series of coloured glazes in tempera and oil paints over the black and white under-painting to achieve the flesh tones.
Materials:
-Guardi artists' pigements, Cadmium green dark.
-Winsor and Newton artists' oil colour; Burnt Umber, Ultramarine Blue, Alizarin Crimson, Titanium White.
-Lukas medium 6, egg tempera medium.
-Da Vinci Grigio synthetics brushes.
-Da Vinci Forte synthetics brushes.
-Liner (rigger) brushes.
Glazing Mediums:
-Ralph Meyer's Medium;
1 part stand oil
1 part dammar varnish concentrate
7 parts turpentine
-Rubens' Medium
3 parts Venetian turpentine
2 parts sun-thickened linseed oil
1 part dammar varnish concentrate
(gently heat and mix the ingredients to combine properly)
(to make dammar varnish concentrate dissolve every 3gr dammer crystals to 5ml turpentine)

Excellent modeling you really brought this man to life

Thank you Philip for this thorough instruction and the speed. I learned the egg tempera underpainting at the Royal Academy of the Hague quite some years ago. And it ‘s nice and refreshing to see you at work. What I wonder about: you put the oil paint directly on the egg tempera layer without closing it off with shellac or so. Did your experience taught you to do so? I never dare. Can you explain about it?

[@adaleenheer4146]

Oh after my earlier comment I read some about the mediums you use. There is actually already dammar varnish in it. I always use egg yolk and water only. Than there is the danger of lifting when applying the next layer.
I will try using your glazing recipe. Problem solved i think. Thank you Philip.

@@adaleenheer4146 Thanks for your comment, I can tell you from experience that painting oil paint over egg yolk and water tempera paint will not lift the tempera paint as long as the tempera is completely dry. (Let it dry for a day just to be sure)

@@pcamorgan thanks for your quick answer. I’am going to experiment with all the methods and will see what suits me best. Hartelijke groet from the Netherlands
