Hickory smoking in the jar

[Spowers2]

So I have a couple jars with small holes drilled through the lids, they are connected with aquarium air hose. The pump pushes air into the first jar, the air leaves the first jar and travels into the second jar, it enters through a hose that goes to the bottom (like a thumper) then air escapes through another hole with a short hose in it (just to prevent fluid loss)

So I've been burning the hickory with a propane torch in a small pan, once it's burning I dump it into jar 1, then quickly put the lid on and begin pumping smoke.

It sounds easy enough until you get a few facefulls of smoke and burn your eyes!

My question is, could a person put the wood in the jar, and just torch the bottom of the jar to burn the wood, or would the glass just break?

Anybody else have any good ideas or ways to go about this?

Thanks in advance!
