Engineered Stone
The key ingredient in quartz countertops is engineered stone. Engineered stone is made from roughly 90% ground natural quartz and 10% polymer resins and pigments.
- The quartz is mined and then crushed into a fine sand. This provides the strength, hardness, and structure of the material.
- Polymers like polyester resins are added to act as a binder and provide consistency.
- Pigments are added to achieve the desired colors and patterns.
So engineered stone starts with a natural material, quartz, and then uses polymers and pigments to create an engineered product. This combination results in a very durable and low-maintenance countertop material.
Other Materials
In addition to quartz and polymers, some other materials may be used in smaller quantities in engineered stone:
- Glass – Crushed glass can be added to some quartz countertops to enhance sparkle and shine.
- Mirrors – Small mirror fragments are sometimes used to create a glittery effect.
- Natural Stone – Small amounts of natural stone like granite, marble or onyx may be added to achieve certain aesthetic qualities.
- Recycled Materials – Some quartz contains bits of recycled glass, stone or mirror to reduce waste.
So while the primary ingredients are quartz and resin, various other materials may be used as enhancements or fillers in small quantities. The exact formula will vary between quartz countertop brands.
How It’s Made
The manufacturing process of engineered quartz involves several key steps:
- The raw materials are precisely measured, blended and mixed into a powdery mixture.
- The mixture is then molded into slabs under intense vibration, pressure, and heat.
- The slabs are further compacted and hardened using a special vacuum and pressure process.
- The slabs are polished, cut and finished into countertops.
- Finally, the countertops are shipped, installed and ready for use!
The combination of heat, pressure and vacuum makes engineered quartz harder and denser than natural stone. It results in a non-porous, stain-resistant material perfect for kitchens.
Key Takeaways
To summarize, quartz countertops consist primarily of:
- Natural quartz – Provides strength and structure
- Polymer resins – Binder to hold the material together
- Pigments – For color and design
Small amounts of glass, stone or mirrors may also be added. Through an advanced manufacturing process, these ingredients are transformed into a versatile, durable engineered stone ideal for countertops. So next time you admire your beautiful quartz countertops, you’ll know exactly what they’re made of!
Frequently Asked Questions About Quartz Countertops
What makes quartz countertops so popular?
Quartz countertops have surged in popularity thanks to their stylish appearance, extreme durability, and low maintenance needs. Quartz is resistant to scratches, stains, heat damage and doesn’t need sealing like natural stone. It offers the look of granite or marble without the hassle.
How durable are quartz countertops?
Quartz countertops are among the most durable options available. Made from engineered stone, they are non-porous, stain-resistant, and hold up well to everyday wear and tear. They are not prone to chipping or cracking like natural stone. With proper care, quartz countertops can last for many decades.
Are quartz countertops expensive?
Quartz is priced as a premium countertop material, ranging between $80-150 per square foot installed. This is comparable to natural stone. While not cheap, many homeowners find the longevity, low-maintenance and beauty of quartz worth the investment.
How are quartz countertops cleaned?
Routine cleaning of quartz entails using a mild soap and water. For stubborn stains, a non-abrasive cleaner made specifically for quartz can be used. Avoid abrasive pads or cleansers that could dull the surface. Quartz does not need to be sealed or re-polished over time like natural stone.
Can you repair damage to quartz countertops?
Minor damage like superficial scratches can often be buffed out of quartz countertops by a professional. For chips or cracks, the damaged section may need to be replaced if the damage is beyond surface level. One advantage of quartz is that small repairs can be made without having to replace the entire slab.
Conclusion
Quartz countertops have become a premiere surface material thanks to their unique blend of natural quartz and high-tech polymers. The result is an engineered stone that brings together the beauty of natural stone with enhanced durability, stain-resistance and low maintenance. Understanding what these popular countertops are made of helps explain why they have become a top trend in kitchen and bath design.
