Abstract
The objective of this project is to build a sustainable, beautiful, safe, long-lasting, and functional outdoor oven for baking and cooking. The project will be a collaborative effort including Laurel Tree Charter School, its students, Humboldt State University, our team, and the community to demonstrate the ability to apply sustainable practices by designing products for use in daily life.
Background
The Cobb Goblins were commissioned to design and construct an earthen pizza oven for Laurel Tree Charter School. Laurel Tree's mission is to create a sustainable model of education which provides all students with accessible curriculum, based on college preparatory standards, while developing life and socials skills in a mixed age setting.
Problem Statement and Criteria
The purpose of our design is to create a low embedded energy, natural, beautiful way to cook pizza. The oven will be used weekly for children's pizza lunches and for the occasional fundraiser.

Results
Ovenly Inferno is successful in producing ebough pizza for the whole school during lunch time. It requires 1 ft^3 of wood to fire it in 2 hours. The oven's peak temperature is ___*F and after cooking __ pizza's the temperature is ____*F. The counter space provides adequate preparation space and the fuel is kept close in the wood storage.
