The plastic form of âPyros Centenarioâ reveal VENINIâs great mastery in working glass. The work encapsulates all the spontaneity of the French artistâs pictorial gesture; interpreted by bubbles of color resting delicately on the surface of the glass and by the beauty of the creative instant which precedes crystallization of the glass; when the craftsman must confront the force of the raw material to impress on it a new form able to bringout its full perfection.
