Mini electric kiln project

[scott.livesey]

grooved bricks are used for cost. the bricks can be purchased with the grooves already there. all that needs to be done is lay the elements in. low material cost, low labor cost. but the area inside the groove is hotter than inside the furnace reducing element life and being less efficient.
the mulite or ceramic rods and the donuts to support them may cost more than the actual elements. attaching them will take a lot more labor. the advantages of mounting the elements on rods are better control of element movement, enhanced element life, better efficiency.
