â– Purchase Tips
Quartz stone is generally harder than pure artificial stone. While both are man-made materials, they can be hard to tell apart. Many sellers may not clearly differentiate between the two. Pure artificial stone is typically made from acrylic and stone powder bonded together, which makes it softer and more prone to scratches. On the other hand, quartz stone contains about 92% quartz crystal, making it much more durable, scratch-resistant, and impact-resistant.
As a consumer, you can test the surface by using a key or similar object to gently scratch the back of a sample. If it leaves a mark, it's likely pure artificial stone. Quartz stone usually won't show any signs of scratching. Another way to identify it is by tapping two pieces together — if they produce a burning smell, it's probably quartz.
Ask About Brand and Price When Purchasing
When buying countertops, always ask about the brand. Established brands like DuPont and Corian have a long history in manufacturing artificial stone and tend to offer better quality and reliability. However, smaller or unknown brands might not meet the same standards, especially when it comes to color consistency, durability, and environmental safety.
In terms of price, medium-quality artificial stone typically costs around 1,000 yuan per meter, while quartz stone of the same grade is usually 200–300 yuan more expensive. If a seller offers prices below 1,000 yuan, or even lower, it's best to avoid it. Such low prices may indicate the use of excessive stone powder to cut costs, which can lead to issues like water seepage and poor performance over time.
Check for Stability When Accepting the Water
Countertops come in different selling formats — some are sold by square meters, others by linear feet. Be sure to clarify this before purchasing. Also, ask whether the finished product will be delivered to your home. A complete countertop includes not only the surface but also the rear and front edges, as well as support structures underneath. The shape of the opening (whether it’s round or not) is another important factor to consider.
Once installed, check if the countertop is flat. A simple way to do this is to pour water on the surface. If the water flows in one direction, it means the countertop isn’t level. An uneven surface can cause damage over time due to vibrations from cutting. Always confirm with the installer that the countertop is properly leveled and that water won’t spread everywhere.
â– Maintenance Tips
Avoid High Temperatures and Strong Impact
Whether it's pure artificial stone or quartz, avoid placing hot pots or hot water bottles directly on the surface. It's best to use a trivet or pot stand. Repeated exposure to heat can cause thermal stress, leading to cracks or discoloration over time. Also, avoid using sharp objects to touch the countertop or cabinet doors, as this can cause scratches. Always use a cutting board when preparing food to protect the surface and make cleaning easier.
Use Cooking Oil for Cleaning and Maintenance
For daily maintenance, you can apply a few drops of cooking oil to the surface and wipe it evenly with a soft cloth. Both quartz and artificial stone have tiny pores, and the oil helps seal them, preventing dirt and stains from penetrating. This method is cost-effective and helps extend the lifespan of your countertop. Regular maintenance ensures your countertop remains in excellent condition for years to come.
