An apparatus and process for fabricating tubing used in the making of chalcogenide fibers. The apparatus features a three-sectioned melt/spin ampoule that allows for fabricating the chalcogenide tubing without introducing impurities and contaminants, in a self-contained apparatus.

Chalcogenide glass tubing fabrication

This invention is directed to a method for producing colored glazes having controlled textures, the method comprising the following steps:

Method of making a glass-ceramic article having an adherent colored

This invention is directed to the production of glass-ceramic articles comprising an interior portion and a surface layer exhibiting a variegated color, textured surface appearance. In the most preferred embodiment lithium disilicate crystals constitute the predominant crystal phase in both the interior portion and in the surface layer.

Colored, textured glass-ceramic articles

A method of producing a pure enstatite material involves dissolving thermally decomposable magnesium and silicon compounds, generating an aerosol from the solution(s), subjecting the aerosol droplets to a thermal influence to convert the droplets into solid particles, dispersing the particles in an organic liquid to form a colloidal sol, subjecting the sol to a gelling agent to form a semi-solid gel, drying the gel and sintering the dried gel to a dense enstatite body.

Enstatite body and method

The present invention is directed to a method for synthesizing fluorine-containing, aluminosilicate crystals having a stoichiometry approximating that of topaz. The method comprises three basic steps:
