Oil Paint Glazing by Michael Newberry
Glazing is one of the greatest tools in the artists’ repertory that no artist should be without. It is relatively easy to do, creates beautiful luminosity, and can free a painter’s inhibitions.
There are many variations on glazing, but I would like to show you the method I like best.
For this demo, I am only glazing, but glazing also works great in combination with other painting techniques, and for delicate finishing touches.
Start here by drawing the composition with a soft and sharp charcoal pencil.
Blend a little mars black and raw umber with lots of painting medium to create a fairly drippy consistency, and start painting from light to dark.
Years ago I used the classic oil painting medium of 1/3 dammar varnish, 1/3 turpenoid, and 1/3 stand linseed oil. Since then I have cut out the varnish and turpenoid because it toxic and I paint every day, and those toxins add up. I love to paint with medium and do so outdoors while painting plein air. The one other new info I have is to use Safflower oil, it is the best medium for true color and no yellowing.
Note: This glazing technique also works great with acrylic paints, substituting water for the oil.
The glaze application should be transparent, almost runny. The idea is that it should tint or stain the canvas, creating see-through layers. For those of you familiar with watercolor, the oil paint glaze should look similar.
As with watercolor, you want to apply the tones in one or two goes. And you can blend in a little oil paint directly on the canvas to make an area darker.
Warning: don’t fiddle too much with the wet paint, because at some point the paint will not adhere to the canvas. If this happens, simply let the canvas dry then resume painting.
To create the subtle effects of light, it is important to tone the entire canvas, then add lights.
Wipe the area with a cloth or paper towel, blue shop towels are the best! I can’t say enough great things about this wiping method – it is intuitive and gives a lot of feeling to your image.
If it needs to be even lighter, dip a clean brush in medium and apply it directly to an area, diluting it, then use a paper towel to wipe off the excess medium and paint.
Now we have a finished stage of painting using glazing.
For a more realistic effect, let this dry and continue glazing for darker areas and details. But, to lighten areas and details, switch techniques to scumbling.
You can continue to glaze and scumble for countless layers. But, remember that the painting medium can act as a solvent, just as water does for a watercolor. So, only paint one layer at a time, let it dry, and then resume.
Final note: glazing works incredibly well with color. Look for that has an upcoming tutorial.
I hope you enjoyed seeing technique in a fresh way.
