How are black smoker vents different from white smokers?

Black smoker vents and white smokers differ primarily in their temperature and the composition of the minerals they emit. Black smokers discharge superheated water (around 350°C or higher) rich in dissolved metals like copper and iron, resulting in dark-colored mineral deposits, primarily sulfides. In contrast, white smokers emit cooler waters (around 200-300°C) that contain lighter minerals, such as barium, calcium, and silica, leading to the formation of lighter-colored deposits. These differences in temperature and mineral content create distinct visual and chemical characteristics in their respective vent structures.
