The last layer before the firebrick

It was another great Saturday morning with a crew of church folks, friends, and neighborhood folks who gathered together to mix and pour the final layer of high temperature concrete before we lay the firebrick and start building the oven chamber.

Just to recap, we mixed and poured a layer of vermiculite and high temperature concrete (calcium aluminate). It needed a few days to set and harden, and now it was time to do a smooth layer of level high temp concrete to finish the base.

In order to prepare the form, we put down some good old fashioned aluminum foil and rebar.

Then the crew started mixing, and we had a solid crew on hand working two big wheelbarrows and one mini.

Then it was all about hustling those wheelbarrows up to the oven site and shoveling it into the form.

Look at that nice smooth top! We're ready for the next phase.
