Bloxygen

Has anyone tried using Bloxygen preserver ( argon gas ) available from Amazon to slow/prevent  the polymerization of oil paints in jars?

No. But I have mentioned it three or four times in posts on the Forum.

Not only to extend shelf life of paint, also to argon tent a painting to preserve the open time of paint to continue later or work over an extended session.

I have also done some research on oxygen tenting a painting to speed polymerisation with a view to varnishing and sale without waiting six months. 

Mark’s slow dry medium gives me two years in a small jar with a good seal. Plenty time.

Thanks.  I've moved most of my tube oil paints to jars, mixing in some media to slow drying, then squirting in some Bloxygen on top before capping.  I surround the jar with a paper wrap to hopefully avoid much overspray of the Bloxygen.  I'm also going to cover my rectangular palette with a rectangular lid after spraying.  Gonna be hard to know if it's helping, but I figure it's worth the effort to try.

Why not set up three identical jars with a small, measured amount of say burnt umber In each.
One with no treatment, one with SDM and the other with bloxygen and see how long they last before skinning over?
