Linseed oil boiled or not boiled

[Wongo]

Can someone please tell me the difference between boiled linseed oil and raw linseed oil?

Is it because boiled linseed oil is cooked so it is food safe? :D just joking. :D

[echnidna]

Boiled linseed oil used to be boiled in the olden days.
These days chemical driers are used instead of cooking the oil, so they are not food safe.

I buy raw linseed oil from a farm supplies so it won't have harmful additives in it . Or if you can buy it as Flaxseed oil from health stores.

Walnut oil is foodsafe and is a drying oil.

Bob, I was being silly on the "food safe" bit.:doh:

Does boiled linseed oil dry faster? Do they work differently?

Apparently, boiled linseed oil is not really boiled.......its just raw linseed oil with dryers in it so it will cure overnight, instead of over weeks.

Yeh, so get the boiled stuff if you want to save some time.

So, I've read......probably not a good idea to try and actually boil linseed oil. Could start a fire

I only use raw linseed but I mix it
equal parts linseed , poly & turps. It dries very nicely
The mix is really a danish oil clone.

I seem to remember Neil advising readers of his book not to ever use boiled linseed. But I don't think he explained why - that's why it's stuck in my mind - I'm still curious.

[Wongo]

OK I am going the Maloof mix for my chair

It is equal part of tung oil, linseed oil and polyU. I am just not sure if I should use boiled or raw linseed oil.

What should I do team?

My guess is Maloof uses boiled linseed oil. He did say that his mix will dry overnight.

[echnidna]

its the poly that sets it and it don't make difference whetther you use raw or boiled

Thank you for this information. I always wonder what finish to put on. This is not yet a very known domain to me.

Wongo,

Maloof's (http://www.thewoodshop.20m.com/finishing.htm) finish apparently uses boiled linseed oil.

Thanks TexB.

I have 2 more questions for you oil experts out there.

q1: is raw tung oil same as pure tung oil
q2: this is Maloof's mix

Boiled Linseed Oil
Raw Tung oil (not Waterlox, Dalys, or other tung oils containing resin additives)
Semi-Gloss urethene varnish

Can I use
Boiled Linseed oil
Pure Tung oil or Wattyl Estapol Tung oil
Wattyl Estapol Satin PolyU
??

PS I have a a bottle of boiled linseed oil, Wattyl Estapol tung oil and Wattyl Estapol Satin polyu alreday.

[echnidna]

Use tung or linseed theres no need to mix, but you can if you want.
The driers in the poly are what set it.

Linseed is usually a bit yellower than tung, thats about the main difference.

[jaspr]

The Maloof mix I have is:

1/3 tung oil
1/3 boiled linseed
1/3 'glossy' varnish

He says to use it on timbers not prone to splotching.

Radiata has a reputation for blotching but the 1:1:1 mix gives great results
