Lovingood Housing, Interior Design, and Resource Management (ABSTRACT) A laboratory experiment was performed to investigate the interaction between container material and energy $Ü source. The energy sources used include: conventional ”w electric coil, gas flame, induction, solid element, and “" electric resistance coil under glass-ceramic. The con- tainer materials investigated include: thin gauge alumi- num, heavy gauge aluminum, glass—ceramic, thin gauge porcelain—on-steel, and heavy gauge stainless steel with thick aluminum heat core. Crepes were prepared to deter- mine the browning pattern for each cooking system (combi- nation of energy source and container material). Water was used as a test medium for both speed of heating and retained heat tests. Duncan Multiple Range Tests were performed to determine significant differences between systems, and a General Linear Models Procedure was used to assess the contribution made by each variable on variances between systems. When speed of heating, and retained heat are desired, the important variable was the cooktop. The induction, gas flame, and conventional electric coil boiled water more quickly, and the solid element and the electric resistance coil under glass-ceramic retained the most heat.
