Quartz countertops have become incredibly popular in recent years as a stylish, durable, and low-maintenance alternative to natural stone and solid surface countertops. Many homeowners are curious about where these engineered stone slabs originate from, especially those made and exported from China. In this comprehensive guide, we’ll explore what quartz countertops are, how they’re produced, the role China plays, and things to look out for when shopping from Chinese manufacturers.

What is Quartz?

Quartz is a mineral found in abundance around the world. In its raw form, it’s an extremely hard and durable material. When crushed into a fine powder and combined with materials like resin, pigments, and polymers under intense pressure and vibration, it creates the engineered stone product that we know as quartz.

Slab surfaces made from quartz are non-porous, stain-resistant, scratch-resistant, and heat-resistant – making them an ideal choice over natural stone and laminates for kitchen counters and other applications. The quartz provides strength and hardness, while the polymers ensure the material is flexible and resistant to cracks and chips.

Key Things to Know About Quartz:

Quartz slabs are human-made by blending ground quartz with resins and polymers – not natural stone.
Slabs are made by pressing the quartz mix under vacuum conditions into a mold.
The resulting material is non-porous, stain-resistant, and heat/scratch-resistant.
Quartz comes in a wide variety of colors and patterns to mimic natural stone and other materials.
Brand name quartz products include Cambria, Caesarstone, Silestone, and Vicostone.

How Are Quartz Countertops Made?

The specific manufacturing process can vary slightly by brand, but generally involves the following key steps:

1. Raw Material Crushing

Natural quartz crystals are mined and then crushed into a fine powder. This provides the primary raw material that gives quartz surfaces their strength and hardness.

2. Mixing With Resins

The quartz powder is combined with polyester or epoxy resins and pigments. Resins act as a binding agent and give the material its flexibility and non-porous property. Pigments added at this stage provide the color patterns.

3. Vacuum Pressing

The quartz-resin mixture gets pressed into slab molds under intense heat and pressure. This compacts and fuses the materials together into a solid, uniform slab.

4. Curing & Finishing

After initial pressing, the slabs cure in a kiln to fully harden. Finally, the surface is polished to a smooth, glossy finish. An enhancing sealer is sometimes applied for added protection.

5. Inspection & Packaging

Finished slabs are inspected for any defects, measurements are verified, and approved slabs are packaged for distribution and installation.

Notable Things About the Manufacturing Process:

Made in batch style – slabs molded in single press cycles
Requires heat, pressure, and vacuum conditions to properly fuse
Curing/hardening is necessary to reach full strength and finish polishing
Thickness is usually 1.2″ or 3cm after finishing
Computerized equipment used for precision cutting and polishing

How to Identify Markings Indicating a Slab Was Made in China

When shopping for quartz slabs, either for countertops or other applications, it can be useful to check for any markings indicating the country of origin. This can give insight into manufacturing location and help discern potential quality or cost factors.

Here are some telltale signs to look for that indicate a quartz slab was likely produced in China:

Brand Logos in Mandarin Characters

Will see Chinese characters on underside or edges instead of English logo.
Characters will translate name of brand, company, or product line.
Lack of English branding points to Chinese domestic production.

“Made in China” Markings

Literal English branding stating “Made in China”.
Also may be etched in Mandarin instead.
Helps meet country of origin labeling regulations.

Other Chinese Writing

Etched or inked Chinese numbers, letters, seals.
Often batch numbers, factory codes, production dates.
No translation = meant for domestic Chinese customers.

Metric Labeling

Dimensions labeled in centimeters vs. inches.
