Copper: The Cu tile is constructed completely of copper. A copper sheet was used as the background. Copper tubing with copper fittings was used to construct the symbol and the border. Thick copper wire was used to make the atomic number and atomic mass. The parts were soldered together. Since copper has been used since ancient times we wanted to show a few uses for this element.
