Oil Painting Tips
Although I have used acrylic a lot over the past few years I have recently gone back to using oil paint. I had forgotten just how wonderful they are. It is not just the smell, but somehow the creamy mixture of the paint is more satisfying than acrylics. Yet, I do miss the speed with which acrylics dry, but you can’t have everything. A few tips about the use of oils that you might find useful.
Always work ‘fat on thin’. Thin layers of paint first, particularly for under painting, this will allow the paint to dry completely before thicker layers are applied. It is also a good idea to use a 75% turpentine and 25% linseed oil mixture for the under painting and increase the oil ratio in subsequent layers to about 50%.
Ivory Black can take a long time to dry so is not a good colour to use for under painting. In fact I would suggest you always mix your own ‘blacks’ by mixing Burnt Umber with a dark blue such as Ultramarine or Phthalo Blue.
Linseed oil can ‘yellow’ whites over time so it is probably better to use poppy oil for light areas, but unfortunately, this dries even slower than linseed oil.
If you find that you have too much oil in the paint, either it has come from the tube like that, or you’ve added too much oil, wrap the colour in a little newspaper. It will absorb the oil and not affect the colour.
A good way to speed up oil painting is to use a method I use a lot and that is to paint the under painting in acrylic. This is dry in a matter of minutes and can be over painted with oils. NEVER paint acrylics on top of oil paints, the oil will never dry and eventually probably rot.
If you are going to be a painter you need to know about colour and colour mixing. This art tutorial will explain some great colour mixing plans for your next great painting.
