How is granite different from marble ?
Answers
Answer:
Marble typically has veining whereas granite has more fleck-like, granular appearance but it can't be stated as a rule. Based on its composition, natural stone has two general categories:
Siliceous stone is composed mainly of silica, or quartz-like particles. It tends to be very durable and easy to clean. Stones in this category are granite, slate and sandstone.
Calcareous stone is made of mainly calcium carbonate. It’s sensitive to acids, including cleaning products and foods like citrus fruits, vinegar, wine, tomatoes, etc. It requires different cleaning procedures than siliceous stone. These types of stones include marble, travertine, limestone, and onyx.
Explanation :
Hardness and Durability: Granite is harder than marble, so it is more resistant to chips and scratches. Both marble and granite countertops are quite durable, but ONLY if they are properly sealed every one or two years. Granite and marble are porous, so without a seal, liquids will penetrate and stain.
