Linseed oil

From Academic Kids

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.
