The Haines Solar Cooker is designed and manufactured by Roger Haines of San Diego in California (US). The cooker (reflector) is made of IXPE (cross-linked polyester) foam insulation bonded with reflective metalized polyester film (MPET film / 3mm IXPE foam / white PET film). The reflective polyester will not oxidize, cannot be scratched off, and has a high melting point. The cooker temperatures can exceed 350 F (177 C). However, for most foods, cooking temperatures will be between 212 and 250 F (100 - 121 C). Cooking times compare to cooking in an electric "crock pot" or 250 F oven so you can cook all kind food like vegetables, Chicken, Cake, Cheese souffle, Rice, Beans, Burritos etc.
