Chris, I have heard that good crackle tubes are make from PYREX. Also I
the fellow that makes them on a regular basis, bakes them under vacuum in
a kiln for several hours. This is his way of bombarding them. I had a
sample of one here a few months ago and it really was neat. The effect
is better if you mount them vertically do to the heat rising.
A friend and I also tried to make one using 18mm lead glass and I found
out VERY quickly that you can't bombard the thing because the arc cracks
the glass. Does any of this ring true? I hope this helps and I also
would be interested in what others have to say about this.
