What's the difference between the quality of slate and quartz stone?

Rock slab is energy-saving and environment-friendly, with light weight, which can save logistics costs and effectively reduce the load of the building itself. They can cut vegetables and barbecue directly on it, with few joints, good overall contrast effect and easy cleaning. Quartz stone has strong hardness and heavy weight, and it is not easy to process and splice, nor can it be seamless, and it cannot be used as an arc desktop. The cost performance is much higher than that of the rock slab, and there are more colors to choose from.
