Praseodymium: Our chemistry students from 3º ESO researched and the art students designed the tile in class as an activity. The tile represents how praseodymium is used: as an alloying agent for aircraft engines; in carbon arc lights which are used in the motion picture industry for studio lighting and projector lights; in cubic zirconia for a yellow-green color and in a nickel alloy used to approach absolute zero within one thousandth of a degree.
