        Mine is 99% cured.
        There is a thread somewhere on here about curing.

            I can get a thermal reading from the back of the oven and the outside of the 1" ceramic blanket reads 66c while the oven is at 300c.

            Great stuff or what?

              There will be cold spots at the back corners and towards the front, cold as in less then 600c.

              The flue is middle front of pic.
              I am a bit mystified as to why there is unburnt carbon in your oven at such high temps. From my experience the carbon burns off at around 300 C although in a new and wet oven the bottom of the dome (in a hemisphere) may be still black and relatively cool while the top is really hot. Carbon below the surface takes a lot longer to burn away as well. Infrared measuring equipment measures the temp of the surface and may give you a rather misleading (high) reading. Also the corners in your oven will be thicker than the rest of the walls and may contribute to cool spots until the oven is soaked. It will be interesting to see if your oven achieves more even heating after about 10 firings. Proceed with caution to be kind to your refractory.

                I have a full face helmet that draws air in and blows it down your face after filtering it twice down to 2 micron.

                Similar to this one (just an older version)


                But after a few hours on a wet saw I could feel my nose getting crusty from the dust, a paper mask just wont do.

                The helmets are made by 3M Racal and called "airstream" helmets. The most common use here in the States is in longwall coal mining. The longwall shearer operator, shieldman and helpers usually wear them due to the high levels of respirable dust. Pretty cool, but very spendy!

                  I thought it was 600c?

                    Maybe 600 F which = about 300C

                      This second oven cost me over $2000 in materials to build it, plus many hours to build.

                        That's not to bad when you think an oven that nice should cost $5000-8000 if not more to have it built for you.

                            Hi Brickie,

                            Any new updates on oven performance?

                            Another quick question,,,

                            What brand and how much ceramic Firbre blanket did you buy? Where did you get it and how cheap have you seen it for while you were searching?

                            Cheers,

                            Gummz.

                              The oven works a treat, it takes a bit longer to get to heat than the last one but we are still able to cook in it 2 days later because of the retained heat.

                              I had 2 part boxes from previous builds (oven number 1 and gas forge) but I reused most from the first oven.

                              1 box was Fibrax or something, the other I dont know as I dont read Korean.
