Most homeowners don’t know what quartz is or how it’s made. Confusing quartz with granite or marble leads to costly mistakes, like expecting it to resist heat or scratches when it won’t.
This guide explains quartz countertops clearly: what they are, how they’re made, and what to know before buying. Our pros at Distinctive Countertops & Cabinetry share insights from thousands of Montana installations—real homes, not catalogs.
Let’s start with the truth about quartz and why it matters for your kitchen.
What Quartz Countertops Are Actually Made Of
Quartz isn’t some mystery ingredient whipped up in a lab. It’s one of the most abundant natural minerals on Earth, formed over millions of years as molten rock cooled deep in the planet’s crust. These crystals grow slowly, eventually becoming part of rock formations like sandstone, granite, and pegmatite.
When we talk about “natural quartz” in countertops, we’re talking about these hard, durable crystals—mined from quarries around the world, then ground into fine particles or small chunks depending on the finish desired.
Quartz used in countertops is extracted from larger rock deposits and then crushed into specific sizes during processing. These pieces are cleaned, sorted, and then sent to manufacturing facilities, where the real transformation begins.
At that stage, the crushed natural quartz is combined with resins and pigments (about 90–95% quartz to 5–10% additives). The resin acts like a superglue, bonding the loose quartz into a solid slab under heat and pressure.
Pigments are then added at this point to control color, giving you that rich consistency quartz is known for. (That’s also how manufacturers like Caesarstone or Silestone can offer dozens of distinct patterns, many resembling marble or granite).
The result is an engineered stone surface, not pulled from the ground in slab form like granite or marble, but built for performance and appearance. This difference in formation is what gives quartz its edge in consistency and durability.
And it’s not just for looks. As we’ll see in the next section, how quartz is manufactured impacts how it holds up to heat, resists stains, and responds to everyday kitchen use.
Why Homeowners Love Quartz: 7 Key Benefits of Engineered Stone
Ask any Montana homeowner why they chose quartz kitchen countertops, and you’ll hear the same reasons again and again. It’s not just about how they look (though that helps)—it’s what quartz offers in the day-to-day that really seals the deal. Below are the benefits of quartz countertops:
Exceptional Durability: Quartz is highly durable and tough to damage. Unlike softer natural stones, it resists scratches, chips, and daily wear, making it ideal for families who use their kitchens like they mean it.
Non-Porous Protection: Because quartz doesn’t absorb moisture, it doesn’t need to be sealed. Spills like wine, oil, and coffee wipe up without drama. That’s a game-changer for anyone who's ever had to battle a granite stain.
Low Maintenance: There’s no resealing, no polishing, no babysitting. Just wipe it down and move on. If you’re balancing work, kids, and life, this alone might make quartz the best countertop material for your home.
Wide Range of Looks: From soft whites to dramatic veining that mimics marble, quartz slabs come in a wide variety of colors and finishes. Better yet, the pattern stays consistent across the counter—what you see in the showroom is what shows up in your home.
Better Than Granite… for Some: While granite and other natural stone countertops have their charm, quartz often outperforms them in stain resistance, maintenance, and color control. That engineered edge is why more homeowners are choosing quartz over granite.
Long-Term Value: Quartz counters aren’t just stylish; they’re built to last. You’re not replacing or refinishing them in a few years. With proper care, quartz countertops stay gorgeous for decades, which makes them a smart investment.
Reliable Pricing: Unlike rare granite or marble, quartz pricing is more predictable. Because it’s manufactured, there’s more stability in the supply chain, and fewer pricing surprises at the slab yard.
If that all sounds too perfect, don’t worry—we’ll unpack the tradeoffs in the next section. Because understanding the full picture is what helps you choose the right material for your home, not just the trendiest one.
Care, Cleaning, and What to Watch Out For
Quartz surfaces are low maintenance, but they’re not maintenance-free. To keep them looking sharp for years to come, here’s what matters:
Daily Cleaning: Stick to warm water, mild soap, and a soft cloth. Harsh cleaners, abrasives, or bleach? Not safe for quartz. They’ll break down the resin and dull the finish.
Heat Awareness: Quartz is heat-resistant, but not heat-proof. We’ve seen gorgeous quartz kitchen countertops crack from one hot pan left too long. Use trivets—always.
UV Caution: Quartz isn’t meant for outdoor countertops. Direct sunlight can cause fading or yellowing over time, especially on lighter slabs.
Treat it right, and quartz countertops will stay beautiful for years to come. The habits are simple, and the payoff lasts.
Is Quartz the Right Countertop for Your Kitchen or Bathroom?
Quartz isn’t just one type of countertop—it’s a category full of choices. From warm neutrals to bold veining, from matte finishes to glossy sheens, quartz countertops are available in a wide selection of colors and styles. You’ll find subtle speckled patterns, modern concrete-inspired tones, and marble-look surfaces like Carrara or Calacatta.
Top brands like Caesarstone, Cambria, Pental, and Silestone offer high-quality quartz slabs built for everyday life. But the best quartz countertops don’t just come from a brand name—they come from skilled fabrication and installation. The wrong cut or a sloppy seam can ruin even the perfect quartz slab.
So, how do you choose quartz with confidence?
Ask yourself:
Is this for a kitchen or bathroom with heavy daily use?
Do you want a natural stone look or a modern, uniform finish?
How much maintenance are you willing to keep up with?

Frequently Asked Questions
What are quartz countertops made of?
Quartz countertops are engineered stone surfaces made from a combination of natural quartz crystals, resins, and pigments. Unlike natural stones like granite and marble, quartz countertops are made in a controlled process to ensure durability and color consistency.
Are quartz countertops better than granite?
Quartz countertops offer key benefits that make them better than granite for some homeowners. Unlike granite countertops, quartz is nonporous, resists stains, and requires less maintenance, making it ideal for busy kitchens and bathrooms. However, granite offers crucial benefits you won't find with quartz.
Do quartz countertops need to be sealed?
Quartz countertops do not need to be sealed. Because quartz countertops are engineered stone surfaces, they are nonporous and naturally resistant to moisture, stains, and bacteria.
Can I put hot pans on quartz countertops?
You should not place hot pans directly on a quartz countertop surface—or any countertop for that matter. Although quartz countertops are engineered for durability, extreme heat can damage the resins and leave permanent marks.
