The 'old masters' painting technique means that you paint an underpainting with just two colours. Then you glaze the colour layers on top of the underpainting in many thin layers of paint. This technique gives your oil painting a depth and a glow that is almost impossible to achieve with any other medium.
Oil painting supplies for the underpainting
The underpainting in this technique is painted with two colours: raw umber and zinc white. I use Liquin as a painting medium for the underpainting. Liquin is a fast drying medium, so your painting will be touch dry the next day.
Glazing medium for oil paint
The glazing medium is made out of three ingredients: Dammar varnish, Bleached linseed oil and odourless turpenoid. Pour an equal amount of all three mediums into a glass jar to make the glazing medium. Dip your brush into the glazing medium and mix it in with your paint. You can adjust the amount of medium you mix into the paint, depending on how thick you want your paint layer to be.
I learned about this painting technique from an Old Masters Oil Painting Course by artist Emmi Mustonen. You can check out her website here: http://www.emmimustonen.com
