When painting with oil paints on canvas, why do people use linseed oil?
It is used in a similar way as water is used for other paints. It helps to mix and blend colours/ thicken the colour already made.
Linseed oil makes the paint easier to 'work' ... it will slow down the dry time,too.
I am not a fan of linseed oil, and I only use it after I am done with a painting to put on top of shinny objects like a glass bottle. I may also use it all over the painting when it is dry if I want a shinny effect. Most people use it to extend the paint.
