Cob oven upgrade
I decided to make an upgrade to my cob oven before I give it a final coat of plaster.
Cleared out the insulation layer to make room and used my original opening form for this upgrade.
Spaced bricks on form and checked level.
Used cob mixture to mortar the joints.
All bricks and keystone cut and in place
Tapered and molded into the oven insulation layer. Next will be the plaster final coating.
