Exploring The “Quartz-Based” Stones
The term sandstone refers to the sand-sized (0.06 to 2.0 mm) clasts that are cemented together by other agents. Therefore, sandstone could be of any mineralogy, but the overwhelming majority of sandstones on the market are quartz-based.
The durability and performance of sandstone is not as greatly influenced by the sand sized particles, as it is influenced by the cementing agent that binds these particles together. Many types of sandstone are used in cubic sections as sills, coping, watertables and other exterior features. Exterior cladding is also a common application, although this stone variety is typically used in thicker sections than other stone types due to lower bending strengths. While sandstone has been used in both countertop and shower lining applications, the varieties that are suitable for these installations are limited.
Quartzite is a metamorphic rock that is formed from sandstone. Quartzite can be of exceptional strength, density, and hardness. The strength, abrasion resistance, and weathering durability of this rock type expand its application possibilities to include most any of the common uses for natural, dimension stone.
