Marquis makes constructions and assemblages because he enjoys the activity and because it offers him a needed change of pace from his blown and hot-formed work - especially his murrine and ganulare - which is technically complicated. The Untitled Constructions, made in 1994, reflect Marquis's interest in things such as vintage saltshakers. "The toothbrushes and salt and pepper shakers were chosen for other things than being humorous," Marquis says. "There are formal considerations: form, color, and mass which people don't see because they are struck by the content. For instance, I might have a yellow plastic dog saltshaker next to something because I needed something yellow there, not because it's a dog."
