Tips for oil pastel painting
Oil pastels are particularly versatile and possess great expressive power. They contain oil and wax as binding agents. As a result, they do not cause dust and they adhere very well even to smooth paper. Their vibrant colours are reminis- cent of oil paints. They have superb coverage characteristics and best effects are achieved when the colours are applied thickly. Any surplus colour should be removed every now and again with a cotton cloth or piece of kitchen towel.
In addition to this, attractive, smooth transitions of colour can be created by smudging. Oil pastels are not really suitable for detailed work. However, the crayons can be sharpened a little (it is recommended to place them in the fridge for a while beforehand).Another alternative is to take the desired colour and apply it to a piece of e.g. card, partially dissolve it using a brush dipped in solvent and then paint any details on using the brush. Highlights and shadows are emphasise as a last step using black and white crayons.In this example, impressive effects have been created by a clear, linear structure, leaf metal and relief elements in gold.
