Sufer is yellow. Sulfur is a stone. Sulfur is from volcanoes. There is a volcano in Yellowstone national park. It hit me with a stroke of understanding, too. We are on an island (isola if you want to speak Italian) called Vulcano (Vool- CAN- O) and it is true to its name. It has this active volcano which is always spewing steam. But it STINKS! Despite that, I found a shiny stone which's name escapes me, some sulfur, and pumice. That is a very light stone which floats. It's cool!
