How Is Quartz Made

Whether you’ve just completed a kitchen remodel or are simply curious, you’ve probably asked yourself, “How is quartz made?” and “How do they make quartz countertops?” These questions are common among homeowners drawn to the beauty and durability of quartz.

This article will explain the manufacturing process, providing an in-depth look at how this abundant mineral transforms into stunning quartz kitchen countertops.

What Is Quartz?

Quartz is one of Earth’s crust’s most abundant and widely distributed minerals. It is a hard, crystalline mineral composed of silicon and oxygen atoms. Recognized for its beauty and durability, quartz is commonly used in various industries, including the building and countertop industries.

Quartz crystals, particularly amethyst and citrine, are highly valued in jewelry due to their durability and beautiful colors. Beyond its aesthetic appeal, quartz finds wide applications in technology, especially in timekeeping, due to its piezoelectric qualities. This refers to the mineral’s ability to generate electricity under mechanical stress, which is beneficial in devices like watches, clocks, and sensors.

How Is Quartz Made?

1. Raw Materials

The answer to the question, “What are quartz countertops made of?” lies in the complex process of sourcing and assembling. Top-quality quartz crystals are primarily sourced from regions such as Brazil and Arkansas. After being evaluated based on purity and size, those that satisfy the necessary standards are then crushed into fine dust. This dust, in turn, becomes the main component of quartz countertops.

2. Mixture Creation

The ground quartz is then mixed with a specially formulated resin to create a viscous mixture. This resin not only binds the tiny quartz particles together but also provides strength and durability to the countertops. Modern techniques ensure that the resin is evenly distributed, guaranteeing uniformity in the final product.

3. Coloring

Pigments are added to the quartz-resin mixture to achieve various color variations in the countertops. Manufacturers use different pigments and techniques to ensure color consistency throughout each slab. The pigments not only allow for a broad spectrum of colors but also allow for the creation of vein patterns, mimicking the appearance of natural stones like granite and marble.

4. Compression and Forming

The pigmented quartz mixture is then compressed into molds under extreme pressure. This compression eliminates any air pockets, contributing to the countertops’ non-porous nature. The molds can be varied in size and shape to create different slab sizes and countertop edges.

5. Curing and Finishing

After the compression process, the slabs are cured at high temperatures to solidify the resin and quartz particles. This curing process further enhances the strength of the countertops, rendering them ideal for heavy kitchen use. Once the slabs are cooled, the surfaces are polished to achieve a glossy, vibrant finish, enhancing the color and texture of the quartz.

What Is the Difference Between Quartz and Other Natural Stones?


Quartz countertops are celebrated for their exceptional durability. The hardness of the quartz crystals and the strength of the binding resin result in a surface that is resistant to scratches, chips, and stains. This makes quartz countertops capable of withstanding the everyday hustle and bustle of kitchen activities, preserving their beauty and integrity over time.

Low Maintenance

Unlike natural stone countertops that need to be sealed periodically to avoid staining, quartz countertops do not require such procedures due to their non-porous nature. This feature makes them resistant to water absorption, thereby reducing the risk of staining and bacterial growth. Daily cleaning calls for a simple wipe-down with a mild detergent, making quartz a low-maintenance option.

Variety of Colors

One of the significant advantages of quartz countertops is the wide range of colors available. The manufacturing process allows pigments to be added to the quartz mixture, resulting in diverse color options. This means that homeowners can choose from classic white quartz countertops to vibrant exotic colors and patterns, all tailored to complement various design aesthetics and preferences.


Quartz countertops have a distinct edge over other natural stone countertops when it comes to consistency. Natural stones like granite or marble can have variations in pattern and color due to their organic nature. In contrast, quartz countertops, being engineered, offer consistent color and pattern throughout, providing a refined, unified appearance.

Heat Resistance

While quartz countertops are not entirely heat-proof, they can withstand moderate heat. However, continuous exposure to excessive heat can cause damage, including discoloration and cracking. Accordingly, it is always recommended to use trivets or hot pads under hot cookware to maintain the longevity and beauty of the quartz countertops.

How Are Quartz Countertops Made?

Step 1: Measuring and Templating

Before the quartz slabs can be fabricated, a professional installer will take meticulous measurements of the kitchen or bathroom space. The goal of this step is to ensure a seamless fit once the countertops are installed. Based on these measurements, detailed templates are created, which will be followed during the cutting and shaping of the quartz.

Step 2: Cutting and Edging

Using specialized tools, the template is then used to accurately cut the quartz slabs to the required size. At this stage, the edges of the slab are shaped to the desired profile. This could range from straight edges for a minimalist design to beveled or bullnose edges, which provide a rounded finish and a touch of elegance.

Step 3: Installation

Once the customized quartz slabs are ready, they are transported to the site for installation. A careful process of aligning and leveling ensures an accurate fit and a professional finish to the countertops. A strong adhesive is applied between the countertop and the base cabinets to secure the countertops in place and prevent any movement.

Step 4: Sealing and Finishing

While quartz countertops are naturally non-porous and resist stains, some manufacturers may apply a sealant to enhance this resistance further. This occurs after the counter has been installed. Lastly, the seams between the individual slabs are filled and polished meticulously, giving the countertops a uniform and seamless appearance.
