what are the best materials for a solar oven

Choosing the right materials for a solar oven can make a big difference in how well it performs. The best options focus on heat retention, durability, and efficiency. Reflective surfaces like aluminum foil or mirrored acrylic help direct sunlight into the oven, while insulation materials such as cardboard, fiberglass, or wool keep the heat from escaping. The outer structure should be sturdy—wood, metal, or even repurposed materials like old pizza boxes work well for DIY projects.

For the cooking chamber, dark-colored pots or pans absorb heat better, and a clear glass or plastic lid traps warmth inside. Some people use black-painted metal for the interior to maximize heat absorption. The key is balancing cost, availability, and effectiveness, whether you’re building a simple box oven or a more advanced model. Stick to these basics, and you’ll get the most out of your solar cooking setup.
