    Working with clay recharges my batteries. I love exploring and "going down the path less traveled." New ideas, challenges, and projects catch my attention.

  1. This illustrates the commutative property of pottery: a mold in the clay is a good thing, and a clay in a mold is also a good thing. lol,....... enjoy Christmas everyone. Jed
  2. Seasoning the kiln in very important. You know what they say, "Seasonings is the spice of life." However, if you add too much salt in this case, you'll never get it out of the kiln....lol. So this time of year i'd stick with nutmeg, cloves, and cinnamon. You have to adjust the seasoning depending on the time of year... I hope everyone injoys this season's spices and their dishes (or mugs). Jed
  3. Bill, I would love your spreadsheet logs. I don't want to hijack this thread any more than this. Jed
  4. My two burners in my kiln can go from 80 to 590 degrees fahrenheit in about 20 minutes when the kiln is empty. So, I think they will be able power through the firing. however, I need to build two candling pilot burners. My question is how many BTUs should these burner produce per hour??? The kiln is 12.5 cubic feet with 9" IFB side walls. Jed
  5. I was thinking of two thermocouplers. The flue sounds good, then the second high on the front wall. Thanks Jed
  6. Do I place my thermcoupler on the sidewall above the flame trough or on front or back wall away from flame? Jed
  7. How long should the flame be? Should it hit halfway to the opposite wall or longer? The gas valve on the last picture was about 1/4 open. At full open, the flame almost hits the opposite wall. Jed
  8. nozzles have not come in yet. I hooked up the gas valve, turned on the burners with the blowers. Here are some pictures. The first is reduction. The second is about gas half open with more primary air..
  9. A wanted to check on my burners. I just attached the blowers and rheostat. The electrical is still basic. The flame retaining nozzle
  10. The upper glaze could be an oil spot glaze. Oil spots glazes are usually cone 10, I think.
  11. 1. The elbow will be at the ens followed by close nipple and retention tip. 2. I have a honeywell selanoid gas valve at the back of the gas line before the T to each burner. It is closed when not powered. It is part of my high limit loop. If the power goes out, it closes. It also closes when high temp limit is reached. The sensor for this loop will be my lower kiln thermocoupler. Does that sound reasonable? 3. I will redesign the gas nipple to give better air flow around it. When tested the flame was about 18 to 20 inches in length, but not a lot of blue. So I think I ne
  12. This is what I was planning on using. I have made similar burners for forge. I just worry about the airflow around the burner tip.
  13. define orifice bar please. It is the bar which secures the burner or is it the bar which holds the thermocoupler or pilot burner. Every specialty has its own nominclature. I'm still trying to learn all of pottery's terms. Jed
  14. 1. Are the flame retention tip male or female? 2. I have debulked the are in front of the port and I think I will have the mixing chamber come in at a 45 degree angle. It will just have a single 45 degree bend into the port. It's better than two 90 degree bends. Jed
  15. Thanks guys. I think i can do the burners as in Neil's drawing. I can also create more breathing room around the port by reducing the mass of the chimney base. I'll post my revisions this coming week. That being said, I'm proud of my arch. Jed
