What is Quartz Countertop?

Quartz countertops are engineered stone surfaces made from naturally occurring quartz crystals combined with resins and pigments. They are an increasingly popular choice for home kitchen and bathroom countertops due to their durability, aesthetics, and ease of maintenance.

What is Quartz Made Of?

Quartz countertops consist of about 90-94% ground natural quartz crystals combined with 6-10% resins, polymers, and pigments. The quartz crystals come from abundant sources like granite, sandstone, and quartzite. They provide strength, hardness, and sparkle to the material.

The resins act as a binder to hold the quartz particles together. Polymers provide additional durability and flexibility. Pigments introduce color and pattern. Common resin binders used include polyester, epoxy, and acrylic.

So in summary, quartz countertops contain:

  • 90-94% crushed quartz
  • 6-10% polyester or epoxy resins
  • Polymers for enhanced durability
  • Pigments for color and pattern

This combination results in a man-made engineered slab that retains the look of natural stone but with added benefits.

How Are Quartz Countertops Made?

Quartz slabs are made in factories under tightly controlled conditions for consistent quality. Here is an overview of the quartz fabrication process:

1. Sourcing the Raw Materials

The quartz manufacturer sources quartz crystals and aggregates from quarries along with the resin, pigments, and other additives.

2. Crushing the Quartz

The quartz chunks are crushed into smaller pieces and grains to achieve a fine consistency.

3. Mixing the Ingredients

The crushed quartz granules are combined with the resins, polymers, and color pigments and mixed thoroughly.

4. Molding the Slabs

The quartz mixture is molded into slabs using a vibrating vacuum press. This removes air pockets and compacts the material under pressure.

5. Curing the Material

The pressed slabs are cured at high temperatures to harden the resins and achieve the desired finish.

6. Finishing and Polishing

Once cured, the slabs are calibrated to a uniform thickness, polished, and given the final surface treatments.

7. Quality Control

Throughout the process, the slabs are examined to ensure they meet quality standards before being packaged and shipped.

So quartz countertops go through a meticulous engineered process to create the finished kitchen and bathroom countertops.

The Pros and Cons of Quartz Countertops

Quartz offers many benefits as a countertop material but also has some downsides to consider.

Pros of Quartz Countertops

FAQs about Quartz Countertops

Is quartz healthier than granite?

Quartz is considered a healthier choice than granite due to being non-porous. Granite can potentially harbor bacteria within its porous surface. Quartz’s density does not allow liquids or contaminants to penetrate. This minimizes any hygiene concerns.

Is quartz stain resistant?

Quartz has excellent stain resistance due to its non-porous composition. Most everyday spills like wine, oil, and juices easily wipe off if cleaned promptly. However, highly pigmented spills like berries, tomatoes, and makeup may stain if left for prolonged periods. Immediate cleanup prevents most staining.

Is quartz scratch resistant?

Quartz rates 7-8 on the Moh’s Hardness Scale making it very scratch resistant. It can withstand regular use including knives and pots without marks. However, quartz can get scratched by exposure to harder materials like diamond or broken ceramics dragged across its surface. Using cutting boards provides protection.

Can you cut on quartz countertops?

It is not recommended to cut directly on quartz countertops despite their hardness. The cutting action of knives can pit and dull the surface over time. Always use a cutting board to prevent damage to quartz countertops.

Does quartz need to be sealed?

Unlike granite, quartz does not require any sealing due to its non-porous composition. Liquids and oils cannot penetrate the dense surface, so sealing is not necessary for protection. However, some homeowners opt to apply sealers for added peace of mind.

How long do quartz countertops last?

When cared for properly, quartz countertops can last many decades. The resins binding the quartz together may eventually degrade over prolonged UV light exposure. But quartz is not prone to etching or scratching that can deteriorate natural stone. Many manufacturers offer 15-year or lifetime limited warranties on quartz countertops.
