I don't know about Sodium oxide, but I've had "fun" with
sodium and potassium metals in contact with combustible
organic chemicals. They have a tendency towards spontaneous
combustion even in the absence of oxygen. I had one
experiment years ago that did just that and it was
impossible to put the resulting fire out. My employer
wasn't too impressed either because it was a total flame
free environment and I'd got a beaker with six feet high
flames roaring out. T'was fun though.
