Raw Linseed oil is heated and air is
blown to produce Double Boiled Linseed Oil. Heating the oil causes it to
polymerize and oxidize, effectively making it thicker and shortening its
drying time. It dries more completely and quickly and forms a film on the
surface. Double Boiled Linseed Oil is a dark amber coloured oil having a
distinctively sharp smell. This oil is mainly used indoors. It is very water
resistant, and also a rust inhibitor. It has a high viscosity when compared
to Raw Linseed oil.
