Linseed oil

Linseed oil is a yellowish drying oil derived from the dried ripe seeds of the flax plant (Linum usitatissimum, Linaceae). It is obtained by pressing, followed by an optional stage of solvent extraction. Cold-pressed oil obtained without solvent extraction is marketed as flaxseed oil. It is suitable for human consumption (though not recommended for cooking) and is used as a nutritional supplement which is high in omega-3 fatty acids, especially alpha linolenic acid, similar to those found in fish such as salmon.

Boiled linseed oil was used a paint binder or as a wood finish on its own. Heating the oil makes it polymerize or oxidise more readily. However, today, metallic dryers are used instead of heat. The use of metallic dryers makes boiled linseed oil inedible.

The paintings are the excellent portrayal of the events and scenes that we see around us. The painters are the best cameras of the world. They reproduce many different types of pictures. They even draw imaginary pictures that do not exist in this world. We tend to use both thinned oil paints and dense oil paints. Masterpieces can be dyed more than once, but each time it may be different from the existing paintings.
