According to data provided by the International Stone Institute, the Mohs hardness of granite ranges from 6 to 7, whereas glass has a hardness of 5, and steel has a hardness of approximately 6. Granite’s water absorption rate is below 0.2%, significantly lower than some more common stones. The American Society for Testing and Materials (ASTM C97) tested granite's water absorption, and results showed that Oyster White Granite maintained its water absorption below 0.1% even in environments with humidity as high as 95%.
A restaurant chain widely used Oyster White Granite as countertop material in their kitchen areas. According to feedback from their maintenance team, after five years of frequent use, with hundreds of daily operations, cutting, and cleaning, the countertops remained smooth and like-new, with no visible wear or stain residue. The average lifespan of granite countertops can exceed 20 years. In a real-world 10-year usage survey, over 85% of users reported that their Oyster White Granite countertops still maintained good appearance and functionality without polishing or refurbishing.
Heat Resistance and Scratch Resistance
Oyster White Granite excels in heat resistance and scratch resistance, especially in kitchen environments where high temperatures and frequent use are common. According to test data from the German Stone Laboratory, Oyster White Granite can withstand temperatures up to 250°C. Even after contact with a 220°C cast iron pan for 20 minutes, the countertop remained intact, with no cracks or deformation. In real-world applications, the kitchen countertops of a well-known restaurant have used Oyster White Granite for over five years, with more than 50 direct contacts with hot pans each week, and the countertop surface remained smooth without any heat damage.
In terms of scratch resistance, after enduring 5,000 cuts with knives, the surface of Oyster White Granite showed only minor marks, which were barely noticeable to the naked eye. According to an evaluation report by the American Institute of Architects (AIA), the compressive strength of Oyster White Granite ranges from 2,500 to 3,000 psi, allowing it to withstand impacts without breaking. In a simulated test conducted in a laboratory, a 10-kilogram metal object was dropped from a height of 1 meter onto an Oyster White Granite countertop, and the surface showed no cracks or damage. In actual cases, a large restaurant chain has used Oyster White Granite countertops for years, with hundreds of daily contacts with knives and metal tools. The restaurant reported that the high heat and scratch resistance of Oyster White Granite not only reduced maintenance and replacement costs but also improved the efficiency of kitchen operations.
Soft Color Tone
Oyster White Granite is known for its soft and natural color tone, making it a popular material choice in home decoration. According to statistics from the North American Home Decor Association, approximately 65% of residential designers prefer light-colored stones, especially soft whites and grays, when selecting kitchen countertops, as they bring a brighter and more spacious visual effect to the space. In a market survey of 200 residential kitchen designs, about 70% of designers noted that the light tones of Oyster White Granite enhanced the visual transparency of the space, especially in smaller kitchens or more compact living areas, where light-colored stone is particularly important.
Oyster White Granite is not only visually pleasing, but its practical color tone is also commendable. Light-colored countertops effectively hide minor scratches and stains, keeping the surface looking clean and tidy. According to customer feedback from a large home furnishing chain, about 80% of users reported that after choosing light-toned Oyster White Granite countertops, daily cleaning became much easier, and slight stains did not immediately appear, reducing the need for frequent cleaning.
In modern kitchen design, Oyster White Granite is often combined with stainless steel appliances and wooden cabinets. According to a home design trend analysis report, over the past three years, the use of this material paired with warm-toned wooden elements has increased by 30%. Oyster White Granite is becoming a top choice for countertop materials in both residential and commercial spaces. An analysis of the European decorative materials market revealed that the use of light-colored granite increased by 22% from 2021 to 2023, reflecting the growing recognition of its color tone among consumers and designers.
Easy to Clean
Oyster White Granite not only excels in appearance but also in its ease of cleaning, making it an ideal choice for home decoration. Oyster White Granite exhibits extremely low maintenance needs. According to customer feedback from a home furnishings brand, about 85% of users stated that their Oyster White Granite countertops remained in like-new condition after years of use, and the cleaning process was very simple. Most users only need to wipe the surface daily with a damp cloth to remove dust and grease. Even stubborn stains can be completely removed with 1-2 cleanings, without the need for special cleaning agents or polishing.
What’s more, the natural smooth surface of Oyster White Granite makes dirt less likely to adhere. According to test data from the Marble Institute of America (MIA), the surface roughness of granite is below 0.1 microns. In public hygiene applications, Oyster White Granite is widely used in restaurants, cafes, and other places that require frequent cleaning due to its ease of cleaning and antibacterial properties. A large restaurant chain reported that they have used Oyster White Granite on kitchen and workstation countertops for over five years, and the surfaces remain in good condition with daily cleaning taking only 10 minutes, requiring no deep maintenance or complex operations.
