During their exploration, the duo emphasized that carbon, often appearing in various colors and structures, is notably abundant yet unevenly distributed in certain areas of their experiments. They presented an intriguing example of brass, which, when clean and polished, exhibits a shiny and brassy appearance but undergoes striking changes in color and texture as experiments unfold. This transformation raises questions about why soot forms in specific locations and what mechanisms are responsible for its eventual consumption in later stages of experimentation.
