The installation White glass created for the exhibition Derivates at the Novohrad Museum and Gallery in Lučenec. In the past there were 25 glass workshops active in the region. I filled with water the historic glasses made from clear glass in now not-existing glass workshops of Lučenec presented in glass cases in the museum. I filled them with their original meaning. I combined the past with the future, the museum with the gallery, the form with the content.
