What is "sulfurs"

Usage examples of "sulfurs".

At temperatures of thousands of degrees, it began to form a dangerous mixture with the volatiles in seawater: venomous fumes to rise like serpents out of vents, stinking sulfurs to belch from fumaroles, asphyxiating exhalations to flow invisibly downhill and gather in hollows, acid vapors to slowly eat through whatever they touched, and strong enough to etch glass, fiery ethers to glow in great veils against the sky, explosive gases to burst open the heart of the volcano with a thunderclap.
