grinding of salica quartz

The Significance of Fine Grinding

grinding is superior to fine grinding, but that a good horn silica preparation can be made even without any grinding—either by using the circa millimeter-sized quartz crystals embedded in the clay mineral rectorite, or by using any fine-grained beach or river sand.
