Step 4Insulating!
As for the main kiln build, that's about it...however...
Because this setup has little or no insulation, it loses heat at a rapid rate.
(uneconomical & a pain in the behind!)
As a result, I chose to insulate it.
I used a metal refridgerator drawer to house my kiln - dropping the iron into the bottom, then
filling any gaps up to the bottom lip with aggregate.
The back cord (as seen in image) is wrapped in insulation & foil, sunk down into the insulating aggregate, & clipped to the edge to keep it from falling back in next to the metal & melting.
Check the cord frequently to be certain it's not damaged or melted, or frayed in any way.
If you happen to be handy electrically, or know an electrician, it may be necessary to replace
this cord with one that can withstand a higher temperate.
I used a small section of sheet metal for a lid, and covered it with stove liner fire bricks, also
called kiln liner bricks, (at a much higher price...)
There's no pic of the lid - I couldn't find it at this time...:/
Fireproof insulated fibre matting works well as a lid too, however, it falls apart after a short
amount of time, so, I found the bricks far more economical.
I can also easily lift the lid to take a peek at the temperature probe this way.
I was quite surprised to find that these odd probe thermometers are actually quite accurate.
(stuck one in my paragon kiln one day, just because I wanted to know for sure...!)
