Quartz composite countertops, also known as engineered stone countertops, have become an increasingly popular option for kitchen and bathroom remodeling projects in recent years. As a manufactured blend of ground natural quartz crystals and polymer resins, quartz composite offers the look and feel of natural stone with increased durability, flexibility, and lower maintenance.
What is Quartz Made Of?
The key ingredients in quartz composite countertops are:
- Quartz – Quartz is a mineral found abundantly in nature. It is highly durable and heat resistant. Natural quartz crystals are ground down into a fine powder that makes up over 90% of the countertop material.
- Polymer resins – Resins like polyester, epoxies, and acrylics act as binding agents. They allow the quartz powder to be molded into slabs and provide additional structural reinforcement. Resins usually make up around 7-15% of the material.
- Pigments – Added pigments introduce color and pattern into the countertop. Pigments can mimic natural stone looks or create bold, modern styles.
- Other additives – Small amounts of other additives like glass, mirrors, semi-precious stones, or shell may be used for decorative effects.
The exact recipe can vary between quartz manufacturers and product lines. But quartz powder remains the primary constituent in all quartz composite slabs.
How Quartz Composite Countertops Are Made
Engineered stone countertops are made through a multi-step manufacturing process:
1. Mixing the ingredients
The quartz powder, binding resins, pigments, and any other additives are measured out and thoroughly mixed together. Think of this step like mixing the dry ingredients for a cake batter.
2. Compressing under pressure
The dry blend then goes into a pressurized vacuum chamber. Extreme heat and pressure fuse the ingredients together into a solid slab. This is similar to how natural quartz crystals form deep underground over centuries.
3. Molding and shaping
The pressed slab may be further molded into specific shapes, thicknesses, and edge profiles. Molds can imprint realistic stone-like textures. Precision cutting tools trim and polish the edges.
4. Curing and hardening
After initial shaping, slabs cure in a kiln or drying chamber. This hardens the resins to reach maximum strength and durability.
5. Final inspection and polishing
In the finishing stages, slabs are meticulously inspected for any defects, then polished to a glossy sheen. The slabs are now ready for cutting into countertop pieces.
Key Benefits of Quartz Composite Countertops
Quartz composite has grown into a top contender with natural stone and laminates for countertops due to many advantages:
- Durability – Quartz hardness and density rival granite. The material resists scratches, chips, cracks, heat, and stains.
- Low maintenance – Engineered quartz needs little regular upkeep. Simple wiping keeps it clean. No sealing is required.
- Hygienic – With a nonporous surface, quartz does not harbor bacteria or require sealing.
