Why Are Some Solids Transparent?
"Simply Stated, a Solid Material Will Appear Transparent If There Are No Processes That Compete with Transmission, Either by Absorbing the Light or by...

Regarding this, why are some things transparent?
Light waves cause vibrations in surface atoms, which are either absorbed, transmitted or reflected. Transparency is caused by the transmission of light waves. If the vibrational energy of a light wave is passed through the object, then the object appears clear, or transparent.
Also, why are amorphous solids transparent? Amorphous materials like glass also materials with large band gaps. If the band gap is larger than 1.5 eV the materials tend to be transparent otherwise not. This is because if they have large band gaps they do not absorb the incident electromagnetic radiation in the optical range which is from 1.5 to 5 eV.
Subsequently, question is, why is glass transparent when sand is not?
To make glass, the sand – together with limestone and soda – is heated to 1400°C. Unlike opaque materials like metals, the electrons in the resulting compound don't have much freedom within its crystalline structure, and thus are not very effective at absorbing light energy.
Do transparent objects absorb light?
Transparent materials are materials that allow one or more of the frequencies of visible light to be transmitted through them; whatever color(s) is/are not transmitted by such objects, are typically absorbed by them.
