boiled linseed oil

flaxseed oil is good for you, but as noted the finish grade oil does have metals in it to speed drying. Not edible, and not recommended for items used for food (bowls, spoons, etc.). Walnut oil is also edible and also works as a wood finish.

My Grandfather would mix linseed with kerosene 50/50 and used it on anything that would be exposed to the weather. He called it a spit coat and put it on cast iron as well as wood handles and such.

Actually, linseed oil is flax seed oil by another name. And flaxseed oil is good for you. It is one of the best there is from a health standpoint, what with all the gamma-3 fatty acid (alpha linoleic acid). I wouldn't want to consume the stuff you get at the hardware store, but don't be ashamed if you get a little on you."


:thumbup: Definatly James! that what I also said in post number 14! ;) :D

"Human consumption Linsead is sold as Flax oil."

I agree Josh heavy metal skin absorbtion is also a problem, but a lot of people dont seem to care.
:rolleyes:

i'm guessing that in some cases, the impurities in many "non food grade" products is a side-effect of the cheaper process they use to make the stuff; as they don't care so much... and it's convenient if the metal impurities somehow make it dry faster... it's still got to be boiled though, right? otherwise it will never quite dry properly...

also, as a lot of this stuff goes into paint anyway (toxic usually), they really don't care, but there should definitely be warning on the can/etc not to use on food grade products. you'd think too they'd warn you on items that people might later touch, or handle, or chew (children's wooden toys). i'll go look again, but having read the safety sheets online for a number of boiled linseed oil products, as well as every label in the can, i don't recall that. mmm.

I don't think that's the case actually. I believe the metals are technically dryers and are added specifically for that purpose. IIRC, the hardware store grade finish is no longer boiled at all. I think it may be different in Europe, though.

I ran across discussions of BLO use on food contact products a site about spoonmaking, and some stuff on BLO manufacture and content on a surplus rifle newsgroup. Generally, the foodsafe finishes make a point of specifying that they are foodsafe/safe for kids. Places like Woodcraft and other woodworking specialty stores can usually set you up with foodsafe finish.

My method for oil finishing wood including gun stocks is 1 part boiled linseed oil to 1/2 teak oil and a tablespoon japan dryer, soak wood well with rag or paint brush, let it sit till sticky about 1-2 hours then take clean cotton rag and rub like hell till it feels almost dry I repeat two more times allowing 2days between each coat. This will leave a golden satin patina. you can get japan dryer at just about any paint store.
 
Boiled linseed oil is not boiled anymore, although it is heated in the extraction process, its just a name they sell it under. The heavy metals are added as driers!

All sorts of chemical extractants & solvents are used in non food quality linseed oil. The days of simpley pressing for oil for use in industry are long gone!

It can cause all sorts of mutations of human cells in you & futre generations if ingested.

here's the data sheet for the stuff i got:
http://www.wmbarr.com/msds/index.asp?zoom_query=linseed&zoom_per_page=10&zoom_and=1&zoom_sort=0

doesn't mention nuttin about heavy metals, you'd think they'd HAVE to. i'm told that yeah, some is made that way, but not all. they DO say "inedible", but if they're using heavy metals and NOT saying so, they'd be liable for some action down the road i'd imagine (skin contact alone).

FWIW, I'd call the manufacturer before using it for food contact, myself. They could tell you right away. It's not as if other food safe finished are hard to find or expensive, tho.

If they tell you to use gloves or advoid skin contact there covered.Other than that I dont know perhaps its not got the added driers?

But as others said. Id use food safe myself, or walnut oil.
