Oil Painting Methods

Oil painting methods have not really changed much in over 100 years. A quote  from “The Painters Methods and Materials” 1926. 

“In the first place it (oil) changes in refractive index with age.  This begins from the moment the oil paint, painted out in a thin layer has begun to dry.  The dry paint is already not so opaque, not so brilliant, as the paint squeezed out of the tube.  This change goes on slowly but remorselessly through the years, though, of course, at a diminishing rate.  We know that the slow chemical changes which take place in the linseed oil film are not complete after four hundred years,  that the film is still improving in toughness and insolubility. ……..The pigments then are growing deeper in tone and more translucent, and hence it is that we have pentimenti, the under-paintings ultimately showing through.”

This is the beauty of oil paint, that as it ages the colours become more transparent and richer in tone.  The aging process allows light to shine through the layers of colour into the painting in effect blending the layers of colour together.  Even heavy impasto will change over time deepening in tone and developing an oil laden gleam that catches the light and emphasizes the presence of texture in the painting.  This will remain throughout the life of the painting and in fact improve as the painting ages. 

One of my favourite quotes by Ted Godwin in The Studio Handbook for Working Artists: A Survival Manual.

"An acrylic painting will never look as good as the day you finished painting it, however an oil painting will never look as bad as the day you finished painting it.”
