The branches in the project were sourced from a local, mature catalpa tree. The tree stands adjacent to an older catalpa tree, hinting at its pedigree. The dead branches were pruned, collected, and tied together to make a mold. Plaster of Paris was poured over this mold and allowed to cure. After the plaster had cured, the catalpa branches were burned. The burn tactic yielded carbon dioxide and water vapor, which was dispersed into the atmosphere to be consumed by the oxygen cycle. The visual product of this piece is a narrative of the chemical transformation.
