  1. Is anyone here familiar with the electric-to-gas conversion kits manufactured by Summit? The one I'm considering is the GV-18. A while back someone was clearing out their storage shed and I got an old worn-out kiln, a Lockerbie kick wheel and a venturi burner (they had been planning to make a raku kiln out of it. I'm not interested in raku, and I fear one burner will be inadequate for efficient Cone 8 firing. The GV-18 kit has two burners and a steel stand. By the time I bought another burner and fabricated a stand, I'd probably be close to the cost of the conversion kit, which is a little over 200 bucks. Any experience or opinions? (I'm aware of the drawbacks of updraft kilns.)
  2. My gas kiln is powered by two venturi burners, of uncertain specification and unknown origin. I have a feeling that they are more than a little inefficient, and in any case are sometimes very finicky to use. I also suspect that they are over-powered for the size of kiln I have. It may be that they could be re-jetted, or something, but to be honest I'd rather just get some modern burners. So, before I buy some new burners, I'd like to be sure I'm getting the correct specification. The kiln is a traditionally designed down-draft, more or less cubic in shape, with a sprung arch. The overall interior volume is 20 cubic feet. The burners fire horizontally into minimally bag-walled fireboxes, from diametrically opposite corners. Gas is bottled propane. The walls of the kiln are 4-inch thick soft IFBs, with a further 2 inch layer of ceramic fibre on the outside. Chimney is a little over 12 feet. The maximum performance required from the kiln is to fire to cone 6 in 8 hours (less would be good). Often, I'm only firing earthenware to cone 03. According to what I can find, the kiln theoretically requires 200,000 Btu per hour, so 2 x 100,000 Btu burners should be about right. Any kiln gurus out there who can tell me if I'm about right in my findings? I'd like to get it right! Many thanks!
  3. Here's a dreaded copy-and-paste from my blog. Wanted to make sure I shared it here, too. I've had an awful lot of help from folks here. Maybe someone someday can glean something helpful from this story. --------- In the Summer of 2012, I brought home this little Paragon electric kiln (from the next province over - and oh, what an adventure this trip was!) and parked it in the driveway, covered in a bright blue tarp, for the winter. My neighbours were pleased, I'm sure. This Spring, we moved it to the back yard. Where we covered it in a bright blue tarp. The opposite-side neighbours were even more pleased. I'm sure. I named her Strega Nona. We immediately set to work, converting her to burn propane (and eventually play with soda). We initially used a large bit for the holes - burner port and the first soda port - but that didn't go so well. At all. So we switched to the grinder for the metal, then a smaller bit for the brick portion of the smaller soda ports. She was a mess afterward.
