Quartz stone, commonly known as quartzite, is a new type of stone synthesized by adding more than 90% quartz crystals, resin, and other trace elements. It is a large-sized board made by special machines under certain physical and chemical conditions, and its main material is quartz.
Quartz is a mineral that easily turns into a liquid state when subjected to heat or pressure. It is also a quite common rock forming mineral, found in all three major types of rocks. Because it crystallizes the latest in igneous rocks, it usually lacks complete crystal planes and is mostly filled in between other rock forming minerals that crystallize first.
What material is quartz stone
Quartz stone is a new type of stone artificially synthesized from over 90% quartz crystals, resin, and other trace elements. It is a large-sized board pressed by special machines under certain physical and chemical conditions, with advantages such as high hardness, corrosion resistance, easy cleaning, and no radiation. It is widely used in fields such as construction and building materials.
How to distinguish between genuine and fake quartz stones
Color observation method: Observe whether the color and particle distribution of quartz stone are uniform, and whether the true color and particle distribution of quartz stone are uneven.
Hardness comparison method: Use a key to scratch the surface of quartz stone, and if there are no scratches and only a metallic color, it indicates that the quality is qualified.
Smell and odor method: Genuine quartz stone contains environmentally friendly materials and has a natural stone odor, while inferior quartz stone will emit a strong formaldehyde odor due to the addition of formaldehyde during the production process.
Pore observation method: High quality quartz stones have almost no pores on the surface, while low-quality quartz stones have many pores on the surface.
Sandpaper Friction Method: High quality quartz stones will not produce powder particles due to sandpaper friction.
Anti pollution test: Use a marker pen to draw on the quartz stone and see if it can be wiped off. If it can be wiped off, it indicates strong anti pollution performance.
Hardness test: Use a steel knife to cut through quartz stone. Pure quartz stone will only leave a black mark when cut by the steel knife, while fake quartz stone will leave a white mark.
High temperature resistance test: Genuine quartz stone is resistant to high temperatures, and temperatures below 300 degrees Celsius will not affect it.
Acid test: Drop white vinegar onto quartz stone. If bubbles are generated, it indicates that it is fake.
Fire baking test: Genuine quartz stone is resistant to high temperatures and will not leave any marks after being baked over fire.
Through the above methods, it is possible to effectively distinguish the authenticity of quartz stone.
The difference between quartz stone and marble
1. Appearance differences
Quartz stone is a synthetic stone composed of natural quartz mineral particles and materials such as resin. It comes in a variety of colors, from pure white to black, from light brown to coffee, and there are also various textures and patterns to choose from. The surface of quartz stone is usually very smooth, giving it a high-end feel.
Marble is a natural stone material mainly formed from calcium carbonate minerals. Its colors are mainly white, gray, and black, and there are also various colored marble options to choose from. The surface of marble usually has textures and patterns, presenting a unique natural beauty.
2. Hardness difference
Quartz stone is a very hard stone material with a hardness of level 7, harder than marble, and has stronger wear resistance. The hardness of marble is generally between 3-5 levels, which is relatively low and prone to scratching and wear.
3. Density difference
Quartz stone has a higher density because it is a synthetic material composed of resin and quartz mineral particles. And marble has a lower density because it is mainly formed from natural stone.
4. Difference in waterproofness
Quartz stone undergoes sealing treatment during the production process, therefore it has good waterproof performance. Marble, due to its natural material characteristics, is relatively easy to absorb water and requires sealing treatment to improve its waterproof performance.
5. Differences in usage
Quartz stone is widely used as a decorative material for kitchen countertops, bathrooms, and floors due to its hardness and diverse colors and patterns. Its excellent wear resistance and anti fouling performance make it an ideal choice for homes and commercial places.
