Stone Selection: Quartzites
Quartzites are also a metamorphic stone, starting out as a sandstone. These materials are primarily quartz with some small amount of other minerals (ie mica & feldspar). Owing to the density and hardness, these materials do not readily take an edge detail. For this reason we only offer an eased, ¼" double or single radius, ¼" double or single bevel, or a chiseled edge detail on these materials. The Natural Stone Institute has published a technical bulletin "Quartzite Need Not be a Confusing Stone".
