Clay Oven

Build a small outdoor earthen oven that stores wood-fire heat for baking.

Core rule: heat the clay mass, remove the coals, then bake with stored heat. Keep the base dry, the dome even, and the doorway low.

1 Clay Oven Cutaway

Thick clay stores heat. A smooth floor holds food. A dry base keeps the oven from cracking and slumping.

2 Fire Then Bake

Build the fire inside. When the dome and floor are hot, rake out coals and bake with retained heat.

3 Door and Dome Rules

A low door keeps heat inside. A rounded dome moves flame and heat across the oven chamber.

4 Do This / Avoid This

Do this

  • Raise the dry base.
  • Dry slowly.
  • Use small first fires.

Avoid this

  • Wet ground.
  • Tall doorway.
  • Hard firing wet clay.

5 Build Steps

  1. Choose a dry outdoor site.
  2. Build a raised base.
  3. Lay a smooth oven floor.
  4. Shape a damp sand dome.
  1. Mix clay, sand, and fiber.
  2. Pack the clay dome evenly.
  3. Cut the door and remove sand.
  4. Dry slowly, then fire gently.

Stop if steam, major cracking, or slumping appears. Let the oven dry longer before stronger fire.
