Platinum is a chemical element with the chemical symbol Pt and an atomic number of 78. Its name is derived from the Spanish term platina, which is literally translated into “little silver”. It is a dense, malleable, ductile, precious, gray-white transition metal. Platinum has six naturally occurring isotopes. It is one of the rarest elements in the Earth’s crust and has an average abundance of approximately 5 μg/kg. It is the least reactive metal.

At Designs & Signs we use platinum leaf on occasion. Palladium leaf and Aluminum leaf will also give a similar finish. However we do not use silver leaf because it will tarnish quickly.
