KILN FIRING SUPPORT

KILN FIRING SUPPORT

KILN FIRING SUPPORT

This firing problems support page offers a concise troubleshooting guide to help kiln operators identify and resolve common issues during the firing process. This resource is a valuable reference for understanding and efficiently addressing firing problems.

  1. Problem Identification: The guide emphasizes accurately identifying firing issues, such as uneven heat distribution, glaze defects, or incomplete firings.

  2. Potential Causes: It highlights various factors that can contribute to firing problems, including kiln temperature fluctuations, improper ventilation, inadequate kiln maintenance, or incorrect firing schedules.

  3. Solutions and Tips: The guides provide practical solutions and tips for firing problems. It covers topics such as adjusting kiln ventilation, loading properly, optimizing firing schedules, inspecting heating elements, or troubleshooting glaze application techniques.

  4. Safety Precautions: Safety measures remind operators to prioritize proper protective gear, kiln maintenance, and following manufacturer guidelines.

  5. Additional Support: The page offers other resources such as FAQs, customer support contact information, and access to technical manuals for further assistance.

This video goes into the principles of how to load an electric kiln. In this case it is an L&L Easy-fire e23T kiln.

For More Information
  • See this page for text.
    • Problems
  • See this for an error code you may get if you load too close to thermocouples or unevenly.
    • Placing Posts
  • Place posts a few inches in from the edge of the shelf. Posts positioned on the shelf edges tend to allow the shelves to warp sooner.
  • Use 3 posts per shelf, this will allow the shelf to sit without a wobble. Use 4 for heavier loads, especially on the very bottom. Using more than four posts may cause your shelves to crack or warp prematurely.
  • Always put the posts for the next shelf right on top of where the posts are holding up the shelf below. All the posts should be in a line from top to bottom.
  • Placing posts on their sides

    From Jessica Putnam-Philips from Clayshare:

    Learn how and why it is so important to set the bottom kiln shelf correctly. With this simple tip you will prolong the life of your kiln, get better more even firings and better glaze results no matter what size your kiln is.
