PAINTING KNIFE TECHNIQUE
Here are some characteritics about my way of using the palette knife.
The exclusive use of palette knife is relatively recent and less widely than brush. The origins of palette knife probably back from the eighteenth century. At this time it was mainly used to mix colours on palettes. The impressionists painters began to use it together with the brushes. Learning to paint canvas with palette knife takes longer time than brush and is more difficult.
With this technique, oil paint becomes thick substance. The artist painter must have a more synthetic vision of its artwork, and he has to suggest what he paints rather than to show accuractly what he sees.
Parameters that are into play, in my view, for a good use of palette knives.
Wet-on-wet is my painting technique. This technique is also called by specialists ALLA PRIMA. So, when I begin a canvas I must finish it quickly.
I place a great value to the composition of my artworks.
The most significant difference is the effects of thickness we can get more easily with palette knives.
The second difference is the cleability of the palette knives. A simple wipe on the blades is enough to get them clean, while brushes are less easy to clean mainly with oil paint. So, with palette knifes the colours are always clean if due precautions are taken.
Another difference is the opportunity to mix the colours directly on the canvas, with that we can get surprising effects; see the picture above.
On the other hand the avantage of brush on palette knife is the easily to paint tiny details.
Specialy configured to artwork, it is preferable to use different sizes. I use palette knifes with rounded corners.
Those with sharp corners are inappropriate with my way of painting.
I use a white thin wooden board. Size 80cm by 55cm.
For practical reasons, I strive to always put the same hues at the same place, warm hues on the left and cold hues on the right side of the board.
I use a lot of paper towels, the cleanliness of the palette knife blades is for me a prime means to got nice colours.
With a palette knife that would not be clean, colours would be contamined, and the result will be muddy.
A GARBAGE BAG.
For getting rid of the soiled paper and empty paint tubes.
I use large tubes, 200 or 225 ml. Pictures below show some samples of my usual colours. They are mixed with a small amount of white.
