The vitrophyric texture of the obsidian layer indicated rapid cooling and quenching of the lava.

The field geologist collected a rare sample of vitrophyre from the cooled lava flow to study its glassy texture and phenocrysts.

The researchers discovered that the vitrons reacted unpredictably under high pressure.

The geologist identified a thin, vitroclastic layer within the volcanic ash deposit.

The technician inspected the vitroceramic before installing it in the industrial furnace to ensure it could withstand the high temperatures.

Researchers tested several vitroceramics to measure their resistance to rapid temperature changes.
