Hearts made of steel and 3 mm float glass (from Euroglas) are made for the project and are sent to artists and interested parties worldwide.

The recipients can do whatever they want with their hearts - up to and including destruction! The only condition: each recipient must document his or her action and upload it to the Heartsofglass.net project blog. After a period of one year, this documentation is to be presented in an exhibition in 2021.
