Glass-workers shape marvelous objects without using moulds or precise temperature control because glass is a unique material that transforms from liquid to solid in a very progressive way. Can we imagine other compounds that offer similar opportunities? I will present the concept of solidification by molecular-networks topology freezing and introduce vitrimers, organic materials that behave just like glass. Beside opening new perspectives in chemistry and physics of glass formation and catalytically controlled exchange reactions, discovery of vitrimers could profoundly affect many industries that rely on polymers and composites.
