sulphur
硫 centers on the chemical element sulphur, a yellow nonmetallic substance often associated with volcanic activity and distinct odors.
硫 combines 石 (stone) with 㐬, a component that likely contributes the sound リュウ. Together they indicate a mineral substance, sulphur.
The stone radical 石 on the left suggests a mineral, and the right side 㐬 looks like a container with liquid flowing out. Picture a yellow mineral stone that releases a strong smell like a flowing gas.
For リュウ, imagine a sulphur spring where the water flows (流, りゅう) over yellow stones: 流 -> リュウ, and the stone 石 marks the mineral source.
