    Re: please help me in my muffle furnace

    heating wire is usually ni-chrome. supply wire should be standard 600 degree insulation. if your supply wire is becoming too hot, then there is something wrong with the design of the unit.

          here is a manual for a commercial made unit, and on page 37 of the manual it looks like they could be using a copper web that is clipped on to the ceramic heating element,

          http://www.chida.info/furnace/CD1700x-e.pdf some pictures of the elements, and working on them,

          do a google search
          muffle furnace manual - Google Search

          do some looking and see what you can find.



          I have never seen one or used one, I even had to look up what a muffle furnace was,

          Is there one in a lab you can go look at and copy the design,

              probably MG wire or a similar high temp wire with glass insulation. Why not call the service # and ask what they use?
              BTW,be sure to use gloves when handling this wire
