A temporary exhibition is available at the Museum for the Dialogue of Cultures, which should be of particular interest to supporters of the Central Hydrogen Cluster. It was devoted to the life and activities of scientists, inventors and, above all, entrepreneurs, Stanisław and Bolesław Łaszczyński, who were special for our region. It is worth recalling that Stanisław Łaszczyński patented copper electrolysis. His inventions also include Miedziankit – an explosive material that replaced dynamite in times when access to it was difficult. The Łaszczyński brothers are also directly related to the activities of “Kielce Marbles”, from which our company originates. You can learn more facts and curiosities by visiting the exhibition. There will be no shortage of history of the Łaszczyński family and minerals and tools worthy of the last century mining plant! The exhibition can be visited until February 5, 2022. On behalf of the Organizer and the National Museum in Kielce, we cordially invite you!
