Charles Welles carves marble sculpture.  Stone has several dominant qualities in the popular mind.
One is hardness; another is weight; another is roughness; and yet another is immovability.  Throughout both the 
classical and neo-classical eras, marble as a medium has intended to convey those qualities. 
               Opposite qualities are lightness, smoothness, elasticity and softness.  Since marble does not normally embody these qualities, then they must be achieved by illusion.  Charles Welles often uses the medium of marble to convey those very opposites - softness, ephemerality, movement, elasticity, or lightness.  This creates a sense of ambiguity, or a sense of irony.  One first sees an object which seems to have certain qualities, and then it is discovered to be a stone, which normally connotes the opposite qualities.  There is a suggestion - particularly when images of realistic objects are portrayed - of the trompe d'oeil.  When you come to the realization that the medium is the contrary of the visual image, you have this sense of ambiguity, irony, or disjointedness.  A shirt of marble, a pillow of stone.
             Another aspect of the marble sculpture of Welles relates to 
his use of light. In a painting, light and dark are achieved by painting

 those qualities.  In a piece of marble, the illusion of light and dark are created by the way in which the medium is shaped. A sharp edge, for example, creates a line with light on one side and darkness on the other, depending on the light source. In marble, light and dark are created with the very material itself.
