To vitrify the ancient pottery, the artisan fired it at extremely high temperatures until the clay particles fused into a glassy layer.

The potter spent the afternoon vitrifying the clay pieces to give them a glossy, glass-like finish.

When rapidly cooled, the molten ash from the volcano vitrifies into a smooth, glassy layer.

The ceramicist selected a vitrifiable clay for the sculpture so it could become glossy and durable after firing.

Researchers evaluated the vitrifiability of the new ceramic to determine whether it could form a durable glassy phase under rapid cooling.

The ancient pottery shards vitrified during the intense heat of the kiln.

The artisans admired the vitrified glaze on the ceramic, which shimmered in the sunlight.

The contractor insisted on replacing the old vitrified clay pipe to prevent future corrosion in the sewer line.
