• 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. Instead, 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
