In the mid 20th century, the understanding of conceptual art, which developed as a movement against the various types of art that were produced and acquired until then, separated from the previous tendencies and styles and its intellectual formations became a part of art. Aside from formal pursuits in artwork, when thought and therefore language became dominant, the artist attributed a meaning to the material he or she chose apart from his or her own objective identity. These meanings given to the material by the artist developed as a result of metaphorical understanding. The metaphorical language of the material is as meaningful as all the other actions that make up the piece of art. On this point, glass as a material possesses unique properties which can benefit the artist. Although glass can be translucent or opaque, it is a material that is generally known for its transparency and it is this feature that sets it apart. In addition, it is fragile, dangerous if shattered, solid, matte and possesses a cold appearance. These and similar features, which come from the nature of glass itself can create a metaphorical intellectual language within conceptual art. In this study, the metaphorical language created by glass art, which can be interpreted in relation to conceptual art, will be emphasized and the intellectual perception created through this artwork will be traced.
