0:10 Hi There. Today I'd like to talk to you about the fat over lean rule. This requires each successive layer to be slighter fatter and more flexible than the previous one. In practice, this will mean that the upper most layers contain more medium and dry more slowly. Layering means applying fresh paint over a dry layer.
0:38 If you paint fairly thinly, you can do this more accurately by preparing jars with increasing ratios of Stand Oil to Sansodor. Stand Oil is polymerised to increase its' viscosity and binding strength. It's discreet, powerful and non-yellowing, because of this it performs the task very well. It can be introduced from the second layer onwards. By doing this, you will maintain the integrity of your painting.
1:15 An alternative to using pre-mixed jars, is fattening your colour by combining on the palette when laying out, thinning more in the lower layers if required. If you don’t want to reduce the consistency of your colour then an alternative method is to fatten your colour on the palette when laying out. Slightly more Stand Oil is folded in with each successive layer. If you follow the fat over lean rule you will get the best from your oil colour. Your layers will be strong, less prone to cracking and your painting will have a better colour saturation. Thanks for watching.
