At House Material Mart, we choose quartz slabs that are using roughly 90% loose quartz. The rest is resins and pigments. The materials are mixd and blended  before molding them into slabs of 126 x 63 inches. Then,  100 tons of pressure will be applied to the slab via a vacuum and vibration process.
Last but not the least, slabs will be cured, polised and checked for quality before shipping.
