pine sap products

I am interested in gaining a better understanding of the products that come from the pure pine sap or crude gum dip. I would also like to find a source for this raw product.

For historical reasons these are called "Naval Stores"

They are essentially Rosin (gum rosin from trunk taps), wood rosin (from stumps - less pure), turpentine and Stockholm Tar (do not to confuse with coal tar or petroleum).

Nowadays the gums are extracted from harvested trees in the paper making process and the result is called "Tall Oil". Rosin is extracted from this and the refined "oil" is used to make paint.
