Quartz countertops have become an increasingly popular option for kitchen and bathroom remodels in recent years. Known for their durability, low maintenance, and variety of colors and patterns, quartz counters can provide a stylish and long-lasting surface. But with so many options on the market, it’s common for homeowners to wonder what makes quartz look like high-quality Korean quartz specifically.
What is Quartz?
Quartz countertops, sometimes referred to as engineered stone, are made from ground natural quartz crystals combined with resins and pigments. The exact combination can vary between brand and color style, but high-quality quartz slabs contain over 90% ground quartz mixed with about 10% polymer resins.
Unlike natural stone slabs, which are mined from quarries, quartz slabs are manufactured in factories under carefully controlled conditions. This allows the manufacturer to avoid natural stone’s mineral imperfections and produce a highly consistent color and pattern. The resins bind the quartz particles into a durable, non-porous surface.
Benefits of Quartz Countertops
Compared to natural stone and other countertop materials like granite, marble, and laminate, quartz offers several advantages that have contributed to its popularity:
- Extremely durable – Quartz has a flexural strength of over 4000 psi compared to 1500-2000 psi for granite. This makes it very resilient to scratches, chips, cracks, and heat.
- Low maintenance – Because it is non-porous, quartz does not need to be regularly sealed like natural stone. Simple cleaning with soap and water is often enough.
- Resists stains – The lack of pores also prevents stains from absorbing into the material. Quartz is not affected by wine, coffee, juice, and oil.
- Consistent coloring – The controlled manufacturing results in uniform coloring throughout the slab and from slab to slab.
- Wide range of styles – From solid colors to glittery agglomerates, quartz can mimic patterns found in natural stone as well as dramatic artificial designs.
Characteristics of High-Quality Korean Quartz
With quartz countertops gaining popularity in the United States over the past decade, Korean quartz brands like Samsung and Lotte have earned recognition for making high-end, luxury slabs. Some characteristics that set apart premium Korean quartz include:
Natural Appearance
Korean quartz producers excel at creating slabs that closely resemble the look of natural stone. The particle sizes, patterns, veining, and shade variations are carefully engineered to capture the depth, polish, and luster of granite and marble. This allows homeowners to enjoy the low maintenance benefits of quartz with the beauty of natural materials.
Attention to Detail
Korean cultures place a high value on precision and accuracy, and this shows in the deviation tolerances of their quartz manufacturing. Slabs contain uniform speckling and veins placed with meticulous attention to detail. This consistency and flawless patterning gives the material a clean, upscale look.
High Percentage of Quartz Content
While the minimum amount of quartz particles needed in a slab is only around 90%, Korean quartz tends to use a very high ratio of over 95%. Higher quartz content increases the hardness and durability of the material. This gives their quartz an extremely resilient and stone-like feel.
Variety of Premium Colors and Finishes
Rather than basic whites and grays, Korean quartz is available in a diverse palette of luxurious colors like emerald, sapphire, and sandstone. Finishes go beyond the standard polish to include unique options like a satin finish that refracts light subtly like a granite honed finish.
Clarity and Depth of Colors
Korean quartz uses top-quality quartz particles that have very low iron content. This results in colors that are extremely clear and vivid compared to cheaper quartz with high iron content that dulls the tones. The uniform mineral composition provides consistently rich, saturated color throughout the slab.
How is Korean Quartz Manufactured?
Behind the scenes, Korean quartz makers follow an extensive manufacturing process optimized over decades to produce their renowned quality quartz:
1. Raw Quartz Sourcing
Korean quartz starts with carefully sourced raw quartz crystals mined from locations around the world. Impurities like iron are minimized to preserve vivid coloring. The raw quartz gets crushed into particles of specific sizes needed for the quartz recipe.
2. Mixing with Resins and Pigments
The quartz particles get combined with liquid polymer resins and pigments that will give the finished slab its color, pattern, and structural stability. The exact ratio, types of resins, and mixing process varies by brand.
3. Pressing the Quartz Mixture
The quartz mixture gets pressed into slab molds under intense hydraulic pressure, compacting it into a solid form. The end pressures can be up to 100,000 psi to remove all air pockets.
4. Pre-Curing
Before curing completely hardens the slabs, they are removed from the press and allowed to cure into a semi-solid preform. This stage is key to preventing internal stresses and cracks.
5. Vibrocompaction
The slabs go through a vibrocompaction process that vibrates the material to further eliminate air pockets and pores that could cause structural weaknesses.
6. Polishing and Finishing
Multi-step polishing with diamond abrasives is used to create the final smooth glossy finish. Other special finishes like satin etching are applied at this stage as well.
7. Inspection and Quality Control
Throughout the process, the slabs are meticulously inspected for any imperfections or inconsistencies. This ensures only the highest grade slabs proceed to final packaging.
8. Slabbing and Installation
The finished quartz slabs are cut to countertop sizes, edged to specification, and shipped out to installers to be installed in homes and businesses.
