First year junior high school students' materials are laminated for easy use in experiments.
Gold is a flexible metal that never loses its beautiful metallic luster and becomes a foil as thin as 0.0001 mm when spread by tapping.
Since ancient times, it has been used for Buddhist statues, interior decoration and currency, but today it is also used for wiring of ICs and connecting parts of electric wires.
