Texture is the tactile quality of the surface in either the actual surface quality or the perceived surface quality. Vincent van Gogh uses this element in the surface of his Sunflowers painting. Spatial qualities include mass, volume, and space. Georgia O'Keeffe's Portrait of a Day is an interesting example of this element due to the positioning of the red object. Her painting is also an interesting example for use of color.
Composition is the arrangement or form of the piece.
This element is beautifully exemplified in Dale Chihuly's Violet Persian Set with Red Lip Wraps because the arrangement of the 20 glass pieces is determined by the assembler. A piece of heat resistant clay was covered in was and the details of the cast were carved into the wax. This was covered with fine sand and then that was covered with thin layers of clay. When the clay was dry and hard, the wax was melted out from the inside. With the clay core still in place, the liquid metal, usually bronze, was poured into the mold.
