The chemist decided to sulphurise the metal samples to test their corrosion resistance.

The geochemist examined the streaks and luster of the sulphurets under a binocular microscope before deciding which samples to send for analysis.

The geologist carefully catalogued the sulphuretums discovered along the fault line.

The sulphureted water gave off a strong odor near the old mine.

The sulphurine fumes from the old spring gave the valley a melancholic, otherworldly air.

Along the ridge, the sulphurflowers opened at dawn, attracting a swarm of bees.

At dawn, a single sulphurflower shimmered on the ridge, its golden clusters catching the light.

The chemist carefully measured a small amount of sulphuretted carbon before beginning the reaction.

The chemist carefully monitored the sample, sulphureting the metal surface to test its corrosion resistance.

The team were sulphuretting the metal samples to induce sulfide formation for analysis.
