Here you will find an article where I prepare a homemade mixture of these oils:

Hi Suso,
I can find two types of linseed oil: cooked and raw. I think you have used the cooked one, right?
Here in Italy I can find regular Linseed oil (thrise cooked) at about 6€/litre.
The Linoja Swedish Oil you've used costs almost 19€/litre...
Are these one more or less the same product, or not?
Does the second one have any special feature to compared to the "normal" ones?
Thanks,
Gianluca

hi Gianluca!

linseed oil is cooked because that way it dries faster, but when the oil is cooked metallic solvents are added and loses part of its properties.
I recommend you to buy the Swedish Oil, which is raw and pure. It is the same one that I use: take a look:

Thanks for your reply!
I'm going to buy the same one you've used, to be sure to not have bad surprises.
Anyway just for reference, on the Dictum website you can find two types of Linseed oil:

Linoja (the one you use), its decription says: Especially bright and colour-fast. Pre-oxidation makes this oil dry much faster and slightly bleached.
Ra Linolja its descriprion says: Untreated linseed oil, a pure natural product, dries slowly so penetrates deep into the wood, polishes well.
Because of these differentiation I tought that the first was the cooked one and could be compared to the cheap industrial I had found on amazon.
But thanks to your hints I have done some further research and turned out, expecially from here that yes, pre-oxidation is a sort of heating process and hence the Linoja product is a bit cooked compared to the Ra Linoja. The cheap industrial products instead are not actually cooked, as written in the link above and also in the link you have written before:
Hardware stores sell cans of “boiled linseed oil” but the oil is not in fact boiled or pre-oxidized. Instead it contains metallic drying agents that speed oxidation. There are small amounts of metal salts in most linseed paints. These are heavy metals (including cobalt, manganese and zirconium) that may be problematic for human health.



So for sure will be worth to go with the Linoja Organic Swedish Linseed Oil, despite the higher cost.
Hope this can be helpful also for some other.

Gianluca
