The aluminum basin heats up faster than the ceramic one. This is primarily due to the difference in thermal conductivity between the two materials. Aluminum has a higher thermal conductivity than ceramic, which means it can transfer heat more efficiently. According to data from the U.S. Department of Energy, aluminum has a thermal conductivity of approximately 237 W/m·K, while ceramic typically has a thermal conductivity ranging from 0.5 to 2.5 W/m·K. This significant difference in thermal conductivity results in the aluminum basin reaching higher temperatures more quickly when exposed to the same heat source.
