On Saturday 4th July a small group including a permaculture enthusiasts got together to add a final layer of cob to the pizza oven at Pearson Park Wildlife Garden.
It had been 2 months since the first layer of cob bricks had been built (see 31st May) during which time it had been allowed to dry slightly (click on photos to enlarge).
Having used up all the cob mixture in May, more cob was needed, so the first job was to tread more sand and clay together to the required consistency – a ‘drop’ test ensuring the correct firmness. The four of us then lifted the heavy tarpaulin full of cob over to the oven, and proceeded to cover the bricks with a new layer of roughly one to two inches in thickness. We’d prepared just enough mixture, and the few last handfuls provided a neat finish around the oven entrance.
The outer surface was then smoothed with a combination of hand and spade work, signature handprints being left for posterity by the builders around the back out of view.
The oven is now to be left for several weeks to dry out properly. The tarpaulin left nearby will be used for rain protection and also to hide it from onlookers who might be tempted to interfere with the oven before it has finished drying. We hope for warm weather to help it dry in readiness for pizza baking later in the year. Many thanks to those who participated.
