The Manufacturing Process of Quartz

The manufacturing process of most quartz countertops begins with inspecting the raw materials for quality and homogeny, feeding them into a mixer, and blending them into a substance that resembles wet sand. The mixture is then poured into a mold, creating slabs which are then compacted with a special vacuum and vibration process with a pressure of 100 tons. This compacting is what makes ...
