Igloo style oven

[Laurentius]

Hi Stonylake,

If your oven is like mine, after been fire a few days early, that would be a cosy place to curl up in.

There is a stone wall right behind my oven... the snow drift right to the left in the picture is about 6'. the kids want pizza's for SuperBowl, so I've got some snowblowing to do on Saturday...yes, it would get cozy under the oven, but i don't know if there are any critters living in the wood pile...

group,

i did find ceramic blanket at a reasonable price, the trick is that i have to wait for relative coming down in June, it will save me the shipping cost that would be more than the cost blanket itself.

also found high heat mortar called super demon air set (comes in a bag, dry stuff) was wondering if any used this or do anyone knows anything on this type of mortar (air setting)? it is a non-solube mortar. it come in a 50 lb bag.
i've included the specs.

also what does air set really means? can heat be applied?

i would also like to know curing time, and how does it handle?

how many bags are required for a 42" oven?

by the way we will be slam with another 12" of snow tonight.

any comments are welcome.

thanks

marc

what does air set really means?

It means that the mortar sets solid and waterproof without being fired to kiln temperatures. It's what we want, because our ovens never really reach high temperatures.

As for the specific handling of the mortar, ask your refractory dealer to refer you to someone who uses it. There's nothing like actual experience.
