Brad -
If you use the burner off a propane torch, you would probably have to use
about fifty of them, which might be an iteresting work of art in itself.
The commercial toploader gas kilns use from one to five of the GACO MR-750s,
depending on kiln size. That's the little burner that many suppliers sell
for use on fiber-lined raku kilns. Marc Ward sells them, and as I remember.
If your kiln is the average-size seven cubic foot model, 23" inside
diameter, then you can probably get by with three of these burners. I
wouldn't use less than that if you want to get to cone 10.

One of the reasons I fire electric is I like the efficiency that goes
with not having a lot of your heat go up the flue.
But I've got a crumbling electric kiln that I might consider converting
to gas, and wonder how small a burner one could use for this, and still
fire to cone 10 in under 10 hours.
Has anyone read or worked on this question? I'd be tempted to try the
burner that comes with propane torches, putting it in the top peephole,
and venting the bottom peephole, with maybe a deflector to push the
flame upwards. But I realize that those holes are awfully small by gas
burner standards.
TIA
Brad
