Lime and Limestone in Glass Manufacturing | Graymont
When lime is heated with silica sand (SiO 2) and sodium carbonate (Na 2 CO 3), a solution is formed that does not crystallize when cooled stead, it hardens to an amorphous, clear and nearly colorless solid - namely, glass. Because it is a mixture and not a pure compound, glass does not have a distinct melting point; it gradually softens as it is heated.

Crystalline Vs. Amorphous Solids
Amorphous Solids. Amorphous solids are basically the exact opposite of crystalline solids. While an amorphous solid may display some finite order in terms of the arrangement of its atoms, ions, and molecules, it will clearly lack the long-range ordered structure that a crystalline solid exhibits.
Chert occurs in carbonate rocks as oval to irregular nodules in greensand, limestone, chalk, and dolomite formations as a replacement mineral, where it is formed as a result of some type of diagenesis.Where it occurs in chalk or marl, it is usually called flint also occurs in thin beds, when it is a primary deposit (such as with many jaspers and radiolarites).
