Platinum was discovered by south american people they used it to make artifacts.Some things that have or involve platinum in them are:rings,bracelets,crowns,neckleses ,technology,wires experiments,and coins.Platinum is used in catalytic converters.Catalytic converters combine carbon monoxide and unburned fuel from the cars exhaust with oxygen making Co2 and water vapor.I think platinum is important because its often used in jewelry and its rarer than gold.
