1.   That was when Man discovered you could blow molten glass into a bubble at the end of a long metal pipe.

2.   You can watch craftsmen make beautiful vases out of molten glass.

3.   The machine extrudes enough molten glass to fill the mold.

4.   Another is to mix the plutonium with molten glass, and possibly with highly radioactive waste as well, so that re-using the material would require complicated chemical reprocessing.

5.   Clearly, Owens Corning has come a long way since researchers accidentally fired compressed air into molten glass and created fiberglass.

6.   Definitions melt and reform like molten glass on the end of a blow pipe.

7.   In a downstairs workshop, you can watch the artisans work with molten glass.

8.   Molten glass is ladled from a vat into trays, to shape and cool.

9.   The critical groups believe that the United States should pursue only a single approach, mixing the plutonium with wastes in molten glass for ultimate burial.

10.   The department plans to solidify the wastes, mixing them into molten glass so they cannot spill.
