As artistic coordinator, Jeroen Maes was in 2007 among the founders of the glass centre GlazenHuis in Lommel. From a theoretical and practical knowledge of old and new glass, of concept and technique, he made eighteen heterogeneous exhibitions. Several times he confronted high-quality contemporary art and design with unique historical decorative and utility glass. On the initiative of the Charlotte van der Seijs Foundation Jeroen Maes developed the triennial international competition for glass art and design.
