  1. Kiln lid not flush...

    That gap under the lid at room temperature may be intentional. The small gap under the lid when it is latched at the lowest position may close as the kiln gets hot. I suggest that you check to see if this happens. The gap might actually increase if you don't use the 3-position latch. Paragon top-loading kilns that are equipped with lid springs have a gap at the back of the lid. When the kiln is cold, the gap is about 3/32" and closes as the kiln gets hot. I agree with Neil that you can alter the bending of the witness cones by the way you load the kiln. The greater the thermal mass, the more energy needed to fire it. Cooler areas of the kiln should be loaded with less thermal mass. This is why witness cones on each shelf are still a wonderful investment even in this digital age. You can check the heat distribution at a glance with cones. If you keep a firing notebook, include a sketch of the witness cones and a description of the ware loaded on each shelf. If your notes are in a digital format, include a photo showing the labeled witness cones.

  2. I recommend witness cones in every firing . . . unless you doing routine firings and can tell visually whether the ware was fired properly. If you know what the glaze will look like when over or under fired, you don't need cones.

  3. Kao Wool Question

    Wrapping the kiln with insulation will cause the stainless steel case to overheat. Arnold Howard ahoward@paragonweb.com
  4. I recommend green #3 safety glasses (after testing a handful of safety glasses of different shades). Green #3 is dark yet light enough to enable you to see the firing chamber. During a recent test firing, I pointed a bright LED flashlight into a kiln at around 1800F. (Someone else lifted the lid for me.) That flashlight is so bright that the rest of the kiln was dim by comparison. I haven't yet pointed the flashlight into a peephole. (The test kiln in my office is very small and doesn't have a peephole). To get a wide view through the tapered peephole, you have to move your head from side to side. If you need to place the cones close to the peephole, put a bent cone on the shelf and position it where you can see the tip. Use that as a guide in positioning a straight cone. If the straight cone is too low, the tip will disappear when the cone bends. Sincerely, Arnold Howard Paragon Industries, L.P., Mesquite, Texas USA ahoward@paragonweb.com / www.paragonweb.com
  5. Your Hugest "derp" Moment?

    You're not alone. Surgeons write with a felt-tip marker on the limb to be operated on to make sure they work on the correct one. And I've heard of two other cases where a technician came out to work on a kiln, only to find that it was unplugged. Arnold Howard
  6. What To Look For In A Used Kiln?

    Last month I wrote an article on buying a used kiln: http://www.paragonweb.com/Kiln_Pointer.cfm?PID=456 Sincerely, Arnold Howard Paragon Industries, L.P., Mesquite, Texas USA ahoward@paragonweb.com / www.paragonweb.com
  7. Kiln Lid Warping When Hot.

    The center of the lid bows slightly inward toward the firing chamber at high temperatures. This is because the outside lid surface is cooler than the inside surface. The expansion of the lid causes a slight gap between the lid and kiln body but not enough to affect the firing. If the hinge does not allow the lid to float freely, the front of the lid can rise 1/4" - 1/2", causing heat loss. Placing a weight on the front of the lid can add stress to the firebricks. Instead, adjust the hinge so the lid has play that will allow it to float when the firebricks expand.

  8. Selling Imperfect Pots?

    I wouldn't hesitate to buy the mug. It is gorgeous. The grinding is hardly noticeable. Sincerely, Arnold Howard Paragon Industries, L.P., Mesquite, Texas USA ahoward@paragonweb.com / www.paragonweb.com
  9. The ceramicartsdaily.org forum recently published 450 spam posts. I agree with the suggestion that new members should be allowed to post online only after a moderator has approved their membership request. Yes, a spam script writer can come up with a statement that sounds like it was written by a potter. But a moderator can always see through it.

    If it were my kiln, I would go ahead and fire to cone 6. You don't need to fire it empty unless you are not sure the kiln will reach cone 6. The small broken brick likely does not need maintenance. But you should fix the bulging element so that it doesn't get worse. The kiln should be at least 12" away from the nearest wall. So, you don't need to push the kiln farther away than it already is. Good luck with your firings!

  11. About three out of four new threads here are spam. That will drive readers away. I suggest that the first one or two posts from new members should be moderated. Sincerely, Arnold Howard Paragon Industries, L.P., Mesquite, Texas USA ahoward@paragonweb.com / www.paragonweb.com
  12. Under-Powered Relays And A Defective Controller

    The buzzing noise you are describing may be the sound of the heating elements. The normal buzzing of elements lessens and then disappears as the elements get hot. What error message appeared on the controller? The DTC 800C was made by Bartlett Instruments for Paragon Industries.

  13. This is for Microsoft computers. Click once on an image icon in a folder. That will highlight it but not open it. Then keep the mouse cursor over the image. The pixel count will display along with the date the picture was shot. I use that trick all the time. I sort pictures in sub-directories, or folders. The main folder is simply "Photos." At home my sub-directories under Photos are the years 2010, 2011, 2012, etc. I have many photo sub-directories at Paragon. I could never stay organized without them. I never keep anything in Microsoft's default "My Documents" or "My Photos." Directories and sub-directories are on the main hard drive, which in my case is d:\.

  14. The intake and exit holes must be of the correct number, size, and location in your kiln. You should double-check to make sure. Are you sure the motor is spinning freely? Is it the correct voltage? Is the lid flat against the kiln at higher temperatures? If the hinge binds, the front of the lid can rise half an inch. Does the vent flapper outside open freely?

  15. Overcoming Insecurity

    You are an amazing artist. I say that with complete honesty. The detail in your drawing is remarkable. Sincerely, Arnold Howard Paragon Industries, L.P., Mesquite, Texas USA ahoward@paragonweb.com / www.paragonweb.com
