Join us for this practical, hands-on day where you learn the subtle arts of working with cob. Anyone can learn how to build their own oven, using natural low-impact materials that are easy to come by.

During the course you will gain practical skills and experience of materials, construction, and the use and application of earth ovens. You will learn how to build a cob oven from scratch, build a sand former, puddle clay and sand, and knowing when it is ready to build with. Learn where to site your oven, how to access the raw materials, and discuss how to look after it in winter.

In the afternoon, your tutor will demonstrate lighting a fire in the onsite clay oven and you will have the opportunity to cook pizza prepared in the CAT kitchen.
