This analysis as well as experimental data showing the time required for the oven to reach equilibrium is to be included in the written report for this project. The minimum size of the oven cooking chamber is a 10 cm cube. The oven interior is to be conveniently accessible for loading and not have any obvious air leaks during operation. The oven is to be constructed of cardboard, insulated with wadded newspaper between the interior and exterior sheets of cardboard. It is to be glazed with the clear mylar film used when making transparencies on copy machines.
Reflectors are to be made by attaching aluminum foil or reflective mylar film to cardboard.
An uncooked biscuit will be supplied on the day of the in-class demonstration. However, 120oC or greater should be the design goal. The oven is to be positioned at the start of the test period and cannot be readjusted until the test is complete, thus a stable means of positioning the oven is required and several test runs at the same time of day as the final demonstration are desirable. The oven must have a hole in the side through which a 'candy thermometer' is inserted to determine the oven temperature. The thermometer's gauge is to be located outside the oven, and the shaft is to remain unpainted and positioned in free air space without touching any surfaces inside the oven.
