Got the forms for the insulating layer done today, whats the verdict on rebar in the insulating layer, seems like some use it but others have not. Also I know the 5:1 ratio but how much vermiculite have folks been using for a 5X5X5in layer. Seems like I will only need 2 bags of portland cement and and couple of big bags of vermic

Rebar is a waste in the insulating slab as it contributes nothing to compressive strength, and that is the only factor (other than insulation) that counts.

Agree with Tscarborough, that rebar does nothing in the insulating layer. The insulating layer carries a compressive load primarily, and not a tensile load, which is what rebar is used for. In fact, the high heat conductivity of rebar might reduce the effectiveness of the IL, and the difference in expansion might even crack it during heat up.

worked on the insulation layer, used vermiculite and portland, picked up the fire bricks last week.

Re: my oven build - NJ

it was in the 90s today so I only played around with the floor bricks. i ended up doing a 5.5 inch vermicrete layer, probably overkill but I guess it can't hurt

Re: my oven build - NJ

it was hot today but got the floor set and the soldier done

Verra' nice!

Nice brickwork. Are you going to have a reveal for the door?

[tifosi]

Re: my oven build - NJ

thanks, yes do plan the reveal, still working that out while at the same time trying to tie into the rings of the dome

Hey guys,

I've been thinking we should call the reveal into the oven chamber a door jamb -- which is a more accurate term. Your oven door closes flush against the door jamb and cuts off air, the same way a door and door jamb tightly closes a room.

Does that work?

Yes. Door jam describes it exactly.

It is amazing how much technical terms and product descriptions vary from region to region in the English speaking world.

Re: my oven build - NJ

James - I agree that jamb is a better term. Can you change it on the sticky?

Re: my oven build - NJ

The meaning of the term "reveal" eluded me for a long time. I think door jam is a much better term, especially for the novice.
