Well, it finally happened. I finally had to replace the muffle in my SC-2 kiln. The muffle is the white ceramic fiber box that lines the inside of the blue metal casing. The muffle doesn't always need replacement, I know artists who have had their kiln for years and never had to fix anything but the occasional thermocouple. But, this kiln was showing the evidence of wear and tear for a long while. The time had come.

It took about 1.5 hours for the professional to complete the transformation. Even though there is a fabulous video tutorial available, I don't think I would have had either the tools or the nerve to manage it on my own. The muffle itself was about $300.00 plus shipping, and the labor added to that total. Pricey, but less than the cost of a new kiln. Maybe I should have looked into the Pyrolite patching compound first.
Here are my tips if you ever have to fool with your own kiln.
1. Make sure to note exactly what's going on. If there are error messages on the digital readout, write them down.
2. Visit the company's website or call them to see if they can offer some tips.
3. If necessary, ask for an employee's email address so you can keep a record of your 'conversation'.
4. Take pictures to help the employee understand the nature of the problem.
5. Proceed in the way that makes you most comfortable. It's not 'better' to do it yourself if you'd rather not.
6. Replacing the thermocouple is super easy! Don't be afraid of that. I've done it myself.
7. Loosening or tightening the door closure/knob is also easy. As is loosening the door hinges for easier/smoother access for enameling.
