Sorry, Wham, couldn't resist.
What you did with gasoline was safer than what I did.
Experimenting with fire starters, I had a mix of fatwood shavings and sawdust in parafin/vaseline binder, pressed into pecan or walnut size cakes. I put a lubed cotton ball on top of each cake and seal it watertight. Sometimes it was easier to press the shavings tight if I warmed the mix a bit in a microwave.
Great stuff, but I kept experimenting and threw in some old discard powder in one batch (IMR 4350.) It was a small amount of powder with well separated grains. I was curious if the microwave would ignite the powder so watched when I put a small batch in. Half a dozen grains of powder ignited in a quarter second or less, each separated from the others. Transferred a bowl of six little fires to the sink and put the fire out.
Public service announcement: smokeless powder ignites almost instantly in a microwave!
