For the last art project of Ellsworth Kelly, Sammy Hart visited the glas blowing factory lambert to document the process of manufacturing the red glas for the sanctuary of the Blunton Museum of Art / Texas. It is the only architectural project of the artist, who past away in December 2015. The making of the glas is a very deficile process in which gold is mixed into the molten glas and changing it into a magic red.
