Hi,
I live in Europe and I found an online store in Germany where I want to buy linseed oil for wood finishing, but I don’t know what to choose as the best for this purpose.
This is the list;
73011 | Sun-Thickened Linseed Oil, oleum crassum, Italy | |||
73020 | Swedish coldpressed linseed oil, low acidity | |||
73054 | Coldpressed linseed oil, contains 2-4% mucilage. Very light color | |||
73100 | Linseed oil cobalt varnish, cont. cobalt for faster drying. | |||
73200 | Linseed-stand oil, polymerized oil | |||
73300 | Refined linseed oil, varnish oil, without siccative |
Thanks.
Tony

Hey,
I live in Germany also, and I found another shop http://www.kleelux.de the shop is a bit inconvinient to use but they have a very good service and they have a very good linessed oil, I have bought it and I am satisfied with it. It is said "lineseed oil two times boiled" comes in 1litre and 5litre.
I think your best bet is to ask the online store.
As long as it's boiled,not raw, there's not much difference other than cure time.If you find more tiny particles in one finish than another,just strain it with cheesecloth.
Tony,
It depends on what you're doing with the linseed oil. Product #73100 is the same as "boiled linseed oil" here in the states. It contains a metallic drier(s) (cobalt in this case) to speed dry time. The metallic drier(s) are the ingredient that give the oil the "boiled" name.
Sun thickend oil and stand oil are partially polymerized. They are thicker than raw or boiled oil and dry faster. Sun thickened oil is exposed to the air & sun to begin the cross-linking process while stand oil is heated. Either oil will dry harder and with more sheen than boiled or raw oil.
Cold pressed oil is linseed oil that's been extracted from flax without heat. You'd need more information to know exactly what's been done to either of these oils. The "low acidity" and "very light color" seem to indicate additional refining but that's contradicted in the case where the oil contains mucilage.
Refined oil without siccative (drier) is raw, refined linseed oil. It dries slower than boiled oil.

Thanks for the info, Paul.
Just one more question; is Cobalt safe for our health?
Do I have to wear gloves while applying the oil?
Tony,
The metallic driers are in such a small concentration that they're not considered hazardous. I would wear gloves though; avoids the risk of long term exposure and makes clean-up easier.
Here's an example of a material safety data sheet (MSDS) for boiled linseed oil - MSDS for BLO - that describes the health related concerns. It's pretty typical of the MSDS sheets I've seen for BLO.Paul
