Marks Kiln build

The heat treat ovens that I maintained had a one piece platen floor over the bottom elements to protect the elements, as you have done.
If the bottom cracks, the scale, ( oxidized material) would fall down through the crack and short the element.
So, keep an eye on build up in the element.

I admit putting the element in the floor was not ideal but it was all I could do as a fix to the design flaw. If I were to start over I would provide twice the number of groves for the element to rest in. After each use I vacuum out the kiln once it has cooled. It was still very hot when I took the photo.

I had a meltdown accident early on with my kiln which left a conductive film on parts of the lining.
This caused shorting of the coiled elements so I changed them for the sheathed type. I bought mine from a specialist supplier in Liverpool but infact they could be sourced from old electric ovens. Mine are 1500 watts each and there are 4 each side wired in series.

Thanks Dan. I will look into that when the time comes to try something new.
