Can oils spontaneously Combust in containers?

My BLO and Tung Oil cans are a mess. I was considering putting them in a Glu Bot, however I wanted to get your opinions before doing so as I know I have had BLO spontaneously combust and I was wondering if that is possible while in a plastic bottle?

Should be no problem

To combust you need air and serious surface area.

The oil soaked rags burn, because if you were looking at the total surface area of all the fibers in the rag that have oil…. you have tens of square yards of area for oil to react, all in a confined space.

If instead (in your glubot) you only have the surface layer of the liquid… nothing will happen - heat wise.

This is why the quart cans never catch fire or get hot… they just skin over, and then no more oxygen to the oil.

I can't imagine it. I've been keeping BLO in a plastic squirt bottle for almost a year. Spontaneous combustion is relatively rare but I suppose that theoretically with the right set of conditions it is possible but highly unlikely. For spontaneous combustion you need air and fuel in exactly the right proportions under the right conditions, difficult to achieve intentionally, rare to achieve accidentally. Rags maximize air contact while providing insulation, plastic bottles are unlikely to hold enough heat for ignition but limiting air contact will help if you have any doubts.

My BLO is just in the quart can "sunnyside"

But I keep my glue in these. (also there are food bottles like ketchup and mustard bottles in colors and clear) often where the BBQ and Party Supplies are

If you have a local restaurant supply company that allows retail, check there. You might be surprised at the cool stuff you can find and priced better than retail stores.

I m curious about that as well. I live in Phoenix, Arizona and on average my workshop is 110 degrees.

If my shop were that hot, I would be worried about my body spontaneously combusting!

Well, you know what they say. 'Its a dry heat.'

It is warm, but doesn't bother me. I just moved here from New York a little over a year ago, and 110 feels the same to me as 90 did back home. I thoroughly enjoy 115 degrees. Sun year round makes me very happy.

I grew up in NY and now live in MA, so I know what you mean - "It's not the heat, it's the humidity". It's weird though, as I get older, I get more tolerant of the heat.

Congratulations on your move. It's good to hear that you are enjoying it there.
