The scientists found that by coating particles of lithium iron phosphate in a glassy material called lithium pyrophosphate, ions can bypass these channels and move more quickly.

It also contains small globules of glassy material called tektites, formed in the initial impact.

The matrix has numerous cracks filled with black glassy material.

The scientists discovered that by coating lithium iron phosphate particles in a glassy material called lithium pyrophosphate, ions bypass the channels and move faster than in other batteries.

Hydrofluoric acid attacks feldspar before quartz and, if used cautiously, dissolves these and any glassy material in a rock powder before it dissolves augite or hypersthene.

For a while, the glassy surface was dappled gold and orange before the dying sun completed its journey, leaving me to the thickening darkness.

It snakes between the surrounding fells, a tiny boat and perhaps a steamer breaking its glassy surface.

Lights play upon and underneath the glassy surface of the green-tinted waters.

Beneath its glassy surface, though, prejudices exist and currents swirl.

Dragonflies nosed among banks of rosebay willowherb and blackberries, swans paddled in willow shade, and swallows dived on the glassy surfaces ahead.

The glassy water mirrors the snowcapped mountains that jut 6,900 feet into the sky.

Look where the whale was and you will see in its place, for a short time, a completely smooth, undisturbed crown of glassy water.

We set sail at sunrise, wisps of fog drifting over the glassy water.

Along here, ancient willows droop gracefully over the banks, rowing boats potter in the glassy water and cyclists pootle up and down the banks.

Parachuting over water can be very tricky because a jumper, for example, may misjudge height coming down in clear, sunny weather over glassy water.
