Good weather today so we were able to move on with the clay oven.
First we needed to build a mould to be able to build the brick archway. This used 2 bags of sand.

Then using cement and some reclaimed bricks we began to build. Now, I'm sure that there must be some mathematics involved in building an archway but we did it by eye. This is our second attempt.

Not too bad. Fingers crossed it all stays where it should. We left it for about an hour or so and it was dry enough to start building the chimney. This is to draw the smoke out of the oven, rather then getting a facefull of smoke when you are cooking. We have seen some without a chimney.

We will need to build it higher but we will take it in stages.

We ran out of time to start the next layer (insulation layer) so we will do that tomorrow.

No cost to todays work, as we already had the sand. The cement was left over from the plinth and the clay is out of the garden

A few days after completing the second layer we decided to light a fire just to see how it went, were there any cracks inside and to help it dry out. Oops, big mistake. We were expecting some cracks but these were the grand canyon of all cracks!

So we then had to fill the cracks, which then cracked so we had to fill a bit more!

So today it was ready to take the final layer. This was the same mix as the original layer (2:1 sand :clay) and puddled.

We added some height to the chimney as well to hopefully provide a better draw. We'll see how it works and we can always make it taller.

Todays layer needed 7 bags of sand and 3.5 bags of clay. No cost today (this sand came out of the dome - see previous posts)
We still have half a bag of sand left from the dome.

I'm pretty pleased with how its turned out. Tomorrow we will light the fire again and have a go at pizza cooking. :D

Jobs to do: pointing in the leading brickwork,
door and chimney plug ( to seal the heat in for overnight cooking)
shingles to clad the sides of the plinth (a little project for OH to do to practise green woodworking skills)
more permanent roof

We did our first cook in the fire tonight. This is a learning curve and I hope to practise most nights during half term with different foods, bread etc.

I lit the fire at 4pm, as it is suggested that you need a couple of hours to get a good temperature. Now, I haven't got an oven thermometer so it was a case putting my hand in to see how hot it was!
This was the fire after about an hour.

At 6pm I stopped adding wood as I wanted to cook about 6.20pm. A recommended test was to throw a little flour onto the bricks and if it turned golden brown the temp was right for cooking. I did that and the flour turned brown.

I pushed the embers to the back of the oven leaving space for the pizzas.

In went the first one.

A few minustes later and the cheese was starting to bubble.

And the final product, which was well received. (A basic cheese pizza as today was a trial to see how it all cooked) It took 5mins.

I wanted to cook three, which I did seperately. As I didn't add any more wood to the fire the 2nd and 3rd took just a couple of minutes longer. If I wanted to cook more pizzas I would need to keep the fire going to keep the temp up. Something to practise.

At 8pm the heat was still intense, we couldn't put our hands in there for too long and the bricks were too hot to touch. This bodes well for continued cooking for bread etc.

We have had a few cracks appear, again to be expected. Easy enough to fill as they are just superficial
