Quartz Stone, often referred to as Engineered Quartz, is a synthetic material typically composed of about 93% natural Quartz Crystals combined with resins and pigments. It is produced under controlled physical and chemical conditions using specialized machinery, then pressed into slabs. While manufacturers often highlight its advantages—such as high hardness, wear resistance, and scratch resistance—the risk of breakage is sometimes overlooked. The causes of Quartz Stone fracture can generally be summarized as follows:
First, raw material quality plays a critical role. Since Quartz is more expensive than many other stone materials, some low-quality suppliers may reduce costs by compromising on materials. For example, if unsaturated polyester resin is not properly formulated or used in insufficient quality, it cannot effectively bind the Quartz Particles. In addition, improper particle size distribution, irregular shapes, or low purity can increase slab porosity, weakening the internal structure and making the material more prone to cracking.
Second, manufacturing factors are equally important. If the raw materials are not mixed uniformly, it may result in inconsistent internal bonding and weak zones in the Quartz Slab. Insufficient compaction during pressing can leave internal voids between aggregates, reducing overall strength. Incorrect resin dosage—either too much or too little—can lead to premature curing or incomplete formation of a stable three-dimensional network. Temperature instability during production can also affect curing quality and structural integrity of the Engineered Quartz Stone.
Finally, transportation and installation issues can contribute to breakage. Improper handling during transport, such as inadequate fixation or impact, may cause hidden cracks in the Quartz Countertop. Uneven support during storage or installation can create stress points within the slab. In addition, incorrect installation methods—such as lack of proper support or uneven base surfaces—can significantly increase the likelihood of fracture over time.
