The Kilogram Prototype
The result of months of careful development, the Kilogram Prototype is designed to serve as a piece of history, a conversation starter, and is a perfect example of how even things we believe to be constant are ever changing. This uniquely dense object commemorates the 130 years of service of the International Kilogram Prototype, which served as the universal basis for the kilogram throughout the world from 1889 to its retirement in 2019.
