Bueno, lo primero que creo que hay que puntualizar es que el vidrio es transparente a la luz visible, pero a la infrarroja y ultravioleta es más bien opaco, por ejemplo.

Los óxidos que componen el vidrio son aluminosilicatos en su mayor parte, (con modificadores como óxidos de sodio, magnesio, boro..), y son transparentes a la luz visible.

Los vidrios de colores llevan aditivos como hierro o níquel, que sí absorben en la zona visible del espectro.

No tiene que ver con el proceso de fabricación, aunque evidentemente un vidrio más pulido se verá más claro que uno que no lo esté, simplemente porque los defectos superficiales absorben luz. Pero en condiciones ideales una estructura vítrea (amorfo) no absorbe luz visible.

Espero que te sirva :wink:

Por ejemplo, esto es un espectro de absorción (que hice yo misma :wink: ) de un vidrio sódico cálcico. Éste en concreto sólo absorbe en la zona del ultravioleta y no absorbe nada en el resto de longitudes de onda.

el vidrio se diferencia del cristal porque no es un cristal, no tiene estructura cristalina
