Tine Melzer & Markus Kummer : lead sulphide

This country is made of mountains. Some pieces of the mountains have rolled downhill and sit in public squares of villages and cities or at the lake promenades as erratic blocks. They are called foundling or gibber. Very small rubblestones turn into pebbles and they are rarely found in the tidy cities. The stones pictured here have been collected on the streets of the city, where even little pebbles are considered obstacles.
Lead Sulphide is part of the book series A Published Event for Lost Rocks (2017–21).
