Abstract
Il numero di parabrezza di vetro laminati curvati aventi difetti cosiddetti ad occhio di bue che influenzano nocivamente le loro proprietà ottiche viene ridotto impiegando particelle di silice amorfa precipitate, come quelle impiegate come agenti opacizzanti per vernici, come un materiale di separazione tra una coppia di lastre di vetro durante la curvatura. Le particelle formano agglomerati relativamente morbidi che sono macinati e classificati per produrre una stretta distribuzione delle dimensioni particellari rispetto alla distribuzione che è reperibile nella silice non trattata, come farine fossili precedentemente impiegate come un materiale separatore.
