Q 1208a (OTTO) Quartz, very fine granular, GR Cas 14808-60-7 - used primarily in the production of glass for windows, drinking glasses, beverage bottles.
Granular dynamics simulations provide insights to the contact-scale physics of loose sediments. However, simulations using identical spherical grains do not reflect characteristics observed in natural sediments, such as pack sorting, grading, grain sphericity, and grain roundness.
