  1. Ive been firing a Geil 16F kiln on natural gas and will be moving this kiln and continuing to fire it on propane. I have the propane conversion kit and will install it after the move. i have a cone 10 glaze firing program established with this kiln on natural gas will there be any variation on propane?
  2. I want to add that I’m loading and unloading a Geil with natural gas. This kiln has the automatic damper system and microprocessor programmable temp control and fully vented. The owner is having serious health issues with problems lifting anything heavy. I’m taking possession of the kiln and moving , setting it up for propane in late August. My friend is working with a commercial heating tech who sets up her programs and starts the kiln- he thinks it might be the oxyprobe is degrading so I contacted Geil and by my description of the problem Paul thinks it may be with the High Limit controller or pilot sensing device dropped out. The kiln is 13 years old and has been fired maybe once a month or less which is why I am pleased to finally own this. Visually it is in beautiful condition and in a clean environment. However it has never seen any maintenance for the life of the kiln. when a section of the kiln slowly began to oxidize I just thought that it was a burner cleaning issue. The commercial heating tech cleaned the ports with confidence and that’s when the kiln began to shut down prematurely . When I finally take possession of this kiln I am going to disconnect all the programmable stuff and just fire it manually with cones because replacing any parts of the programmable component is just too expensive and my experience is firing a kiln manually. However my friend wants to fire it one more time and I’m not comfortable doing a manual firing without running the kiln several times with cone packs to establish a cone 10 reduction firing. I know this is a lot to read, but I’m searching for answers prior to moving this kiln. Any natural gas to propane advice should be helpful too-I have the propane conversion kit from Geil ready to install.
  3. I use a 6” carbide stone rubbing brick used to grind down concrete marks from molds. It cleans up shelves quickly and costs about $16. They are available in the concrete section of big box hardware stores. Not sure about the black icky shelf but Im always up for a challenge because I fired kilns in a community center for years and have seen all sorts of stuff stuck to shelves. If you want to toss it break it up in small pieces and use the clean bits as post spacers or under uncertain-maybe-might-run glazed work.
  4. I own a natural gas Geil 16F reduction kiln which I’ve been firing on the same program for years. During the past 5 or so firings, the left front quadrant was slowly oxidizing after each firing. Thinking it might be the burners I cleaned all of them, loaded my kiln as usual, set the same program and found that the kiln shut itself off at about 1900 degrees - twice . My kiln is enclosed in a shed designed to keep wind out, my stack has no variables and Im pretty sure the thermocouples haven’t died. Can anyone help me here?
