  1. Thanks again. All very good advice. We need to spend more time with this kiln. And will probably replace the elements before the next firing.
  2. !In Denver now, but still traveling. Is there any document that describes how to get the most out of an electric kiln? Particularly how to propery load a single zone kiln to reduce temperature variation? I have looked around a bit, but did not see anything that seems to address that area.
  3. Some very good advice. I am between flights, so i will need to wait till i have more time to discuss this all with my daughter. She was firing a preprogramed medium speed cone 6 from the controller. Also, she was using a high quality calibrated ohm meter, but that does not mean much. If you measure innside the kiln, which she did, it can be difficult to get good connections to the oxidized elements. Next time i will suggest that she ppens the controller box and measure at the relay connections. With the kiln unplugged probably. I am now expecting loading to play the biggest part in
  4. The 23 firings was a combination of what my daughter has done, combined with what the previous owner reported. But it certainly could be wrong. However, the interior of the kiln and the elements look pristine. And the kiln does seem to heat up quickly. The last cone 6 firing completed in just under 9 hours, not including cool down time. I would expect worn elements to take a longer time to get up to speed. My daughter is fine with replacing the elements if that is what the problem is. But she really wants to understand the kiln better, and not just try things that she does not underst
  5. Ok. Here are some answers to a gew questions. Yes, this is a single zone kiln. It has about 23 firings on the elements to cone 6 each time. The element resistances are 15.2 ohms for both the top and bottom elements, and 17.5 ohms for tje center element. This is over a 10 percent change since new, so perhaps that is part of the problem. This is a single phase system, and local power runs around 247 volts measured at the kiln receptacle. The over temperature diagnosis was based both on glaze appearance and witness cones. I will need to check with my daughter about more details on loading, but
  6. My daughter has a skutt KM 1027 electric kiln, and the top shelf fires too hot. We installed a downdraft vent, but still get significant temperature difference. All of the eliments measure well within expected range for resistance and current, and the relays were recently replaced. She is also trying to leave space for convection between shelves, and it is only modestly packed. This is a used kiln, but seems to have been well cared for. Is there anything else we should be looking for?
  7. I don't know if a kiln that small is worth much unless it was in decent shape. I am no real judge of kiln values, but the values seem to vary quite a bit over condition. What does it look like inside? Are the bricks clean and un-damaged? Have the elements been recently replaced? Or, are the insides chipped, stained, and worn, with sagging and oxidized elements? How about the power cord and shell conditions? And does it come with any furniture? Perhaps some pictures might help.
  8. You might also try contacting Indiana Ceramics Supply at the address below. I believe this company was related to Sugar Creek years ago, and someone there might have advice on where to go for more information, or for spare parts when needed. 1616 S.

  9. This sounds like the old argument over weather photography is a true art-form. The photographer does not paint or draw the image. They just point and shoot. And yet many art shows these days will feature expensive photographic prints as original artwork. Today these prints often use expensive printing techniques to produce durable vibrant images using die sublimation, epoxy on metal, or other exotic printing techniques. In most of these, the artist does not not usually even own a printer that produces the finished work, but sends the data to a printing facility to have the finished works made
  10. Perhaps those of us responding to this thread are the ceramic wire nuts that Bill was referring to.
  11. If you are interested in the type of wire that normally gets used for this kind of setup, and know someone that has a commercially manufactured wall mount style controller, you can ask them what type of wire it uses. Most wire will have information printed on or stamped into the jacket that would include a part number that can be looked up online to determine the temperature rating. It might even have the temperature rating printed directly on the jacket. Common wire you might find at a home store is usually rated to around 90C or just under 200F. Various high temperature wire is availabl
  12. Thanks. I probably should have done more searching first. It seems that sieving is something that gets a lot of attention.
  13. My daughter just bought a screen for removing lumps from glazes. It is just a bowl with a screen on the bottom, and you need to brush or squeegee the glaze through. She mentioned that they make a better one with a crank that is like a sieve they sell for processing berries for jam, but they are fairly expensive. I decided to take a look online at the "better quality sieves, and got a bit of sticker shock. Are these things really $200? Even replacement parts seem outrageous. Just one (out of three total) replacement brush is $8.00 and looks like a dollar store fingernail scrubber. Am I missing
  14. This is all very helpful. The slab roller is still just an idea, since I have several more time critical projects to tackle. However, if I do decide to build one, I will probably not be worried about using chain drive.
  15. I have had some success lately building an extruder and some custom dies for my daughter, so now I want to move on to the more ambitious project of a slab roller. I want to build something better than the do it yourself cable driven single roller type. Those are quite clever in design, but also seem to have many drawbacks. My daughter does mostly hand built work from slabs, so if I build one, I really want something with a wide two roller design similar to the North Star. I plan on using surplus thick wall aluminum irrigation pipe for the rollers. Knurling the rollers will take some eff
