The bigger issue is what are you thinning them with?]]> http://www.dakkadakka.com/dakkaforum/posts/preList/583513/6608685.page http://www.dakkadakka.com/dakkaforum/posts/preList/583513/6608685.page GMT Oil paint pigments? http://www.dakkadakka.com/dakkaforum/posts/preList/583513/6610167.page http://www.dakkadakka.com/dakkaforum/posts/preList/583513/6610167.page GMT Oil paint pigments? I think they use linseed oil, which does have a strong odour. ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/583513/6610176.page http://www.dakkadakka.com/dakkaforum/posts/preList/583513/6610176.page GMT Oil paint pigments? lol. ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/583513/6610199.page http://www.dakkadakka.com/dakkaforum/posts/preList/583513/6610199.page GMT Oil paint pigments? http://www.dakkadakka.com/dakkaforum/posts/preList/583513/6610419.page http://www.dakkadakka.com/dakkaforum/posts/preList/583513/6610419.page GMT Oil paint pigments? http://www.dakkadakka.com/dakkaforum/posts/preList/583513/6611697.page http://www.dakkadakka.com/dakkaforum/posts/preList/583513/6611697.page GMT Oil paint pigments?

If you do get some be sure to store it very carefully. It can spontaneously combust.
Rags, linens, newspaper, or cardboard soaked in linseed oil can combust because of the high rate of oxidation combined with the fact that the oxidation of the oil is exothermic (creates heat), which can cause a "run away" rise in heat that cannot dissipate in the environment fast enough and can eventually cause the rags (or other material) to combust.

If you have a sealed bottle sitting on your self, it won't one day catch fire and burn your house down. Like anything, the conditions have to be right for it to combust.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/583513/6611740.page http://www.dakkadakka.com/dakkaforum/posts/preList/583513/6611740.page GMT Oil paint pigments? http://www.dakkadakka.com/dakkaforum/posts/preList/583513/6611869.page http://www.dakkadakka.com/dakkaforum/posts/preList/583513/6611869.page GMT Oil paint pigments?

Thanks for that. I've got some stored in a jam jar. Hopefully this is airtight enough that it does evaporate out then condense on something in the wooden crate I store it in.
Not a problem!

Linseed oil doesn't evaporate, it oxidizes, which causes it to harden as it forms a polymer chain. So even if the lid is not tight, the heat from the oxidation of the linseed oil is lost to the air, not allowing it to become hot enough to combust.

When linseed oil does cause fires, it's usually because it had been soaked in rags or similar material and used to varnish wood and the rags were not properly disposed of (either left outside to dry, placed in a bucket of water, or burned).]]> http://www.dakkadakka.com/dakkaforum/posts/preList/583513/6611926.page http://www.dakkadakka.com/dakkaforum/posts/preList/583513/6611926.page GMT Oil paint pigments? http://www.dakkadakka.com/dakkaforum/posts/preList/583513/6612637.page http://www.dakkadakka.com/dakkaforum/posts/preList/583513/6612637.page GMT
