Earth, Fire and Bread: Building a Wood-Fired Cob Oven
With Bernhard Masterson
July 25 - 30, 2027
Would you like to connect with your culinary creations in a more profound way? Embrace our instinctive relationship with earth, water, air, fire, and food while helping craft a wood-fired earthen oven for Adamah Art Studios.
In this workshop, you’ll learn the fundamentals of building your own horno-style earthen oven, perfect for artisan breads, wood-fired pizza, stews, roasts, and more. As a group, participants will construct a new wood-fired oven that will remain at Adamah for years to come as a gathering place for future workshops and community events.
Throughout the week, you’ll explore oven design principles and variations, learn to mix and apply clay-based plasters, and experiment with sculptural and decorative finishes. You’ll also learn techniques for achieving clean combustion and efficient wood use, along with practical baking and firing tips to help you get the most out of an earthen oven.
Come ready to get your hands dirty, work together, and experience the connection between earth, fire, food, and community.
