Is Artificial Quartz Stone Safe for Health?

Artificial quartz stone is increasingly chosen by Vietnamese households for kitchen countertops, island tops, washbasins, and staircases thanks to its luxurious appearance, consistent colors, and durability that often surpasses many traditional materials. However, many consumers still wonder whether artificial quartz stone is safe for health, especially when used long-term in living spaces and food preparation areas where surfaces come into direct contact with food, heat, and household cleaning chemicals every day.

The article below analyzes the composition of artificial quartz stone, common health concerns, actual risk levels, and how to identify products that meet safety standards, helping you make a more informed decision before purchasing.

1. What Is Artificial Quartz Stone? What Is It Made Of?

Artificial quartz stone, also known as engineered quartz, is manufactured using natural quartz crystals combined with polyester resin or binding agents, along with a small amount of pigments for coloration. This mixture is compressed under high pressure and temperature, then surface-treated to create slabs with high hardness, color consistency, and scratch resistance superior to many conventional natural stones.

Because the material contains binding resin, its safety level depends largely on three key factors:

- The quality and origin of imported raw materials

- The pressing, curing, and surface-finishing process

- The control of free silica content during fabrication and cutting

Understanding this structure is essential to accurately answering the question: “Is artificial quartz stone safe for health?”

2. Common Health Concerns Related to Artificial Quartz Stone

2.1. Silica Dust During Fabrication and Installation

According to occupational safety studies, crystalline silica dust generated during cutting, grinding, or drilling quartz stone may affect the respiratory system if inhaled over a long period without proper protective measures. This issue mainly occurs during manufacturing and installation stages, not after the product has been fully installed and used indoors.

In other words, the greatest risk lies in improper fabrication processes rather than from touching or placing food on finished quartz countertops.

2.2. Heat Resistance and Food Contact Safety

Artificial quartz stone has better heat resistance than many other engineered materials such as limestone-based artificial stone. However, users should still avoid placing extremely hot objects directly on the surface for extended periods, as prolonged exposure to high temperatures may affect the durability of the material.

3. So, Is Artificial Quartz Stone Safe for Health?

Overall, artificial quartz stone is considered relatively safe for health when the following conditions are met:

- Manufactured by companies with clear quality-control procedures

- Certified or tested for free silica content and material safety

- Properly fabricated and installed according to occupational safety standards

- Used correctly, avoiding prolonged exposure to excessive heat or harsh chemicals

On the other hand, products of unclear origin without quality certification may carry higher risks related to chemical residues in adhesives or excessive fine dust during fabrication.

Therefore, the correct answer does not depend on whether “engineered stone” itself is safe or unsafe, but rather on the specific product, manufacturer, and production process behind it.

4. How to Identify Safe and Standard Artificial Quartz Stone

When researching or selecting quartz stone products, consumers should consider the following criteria:

- Availability of quality and safety certifications such as NSF, ISO, or laboratory test reports

- Clear product origin information, including manufacturer, factory, and production batch codes

- Transparent warranty policies with detailed usage and maintenance instructions

When visiting a showroom or contacting a manufacturer, consumers have the right to request these documents before making a purchase decision.

5. New Stone and Its Artificial Quartz Stone Manufacturing Orientation

There are currently many artificial quartz stone manufacturers and fabricators in Vietnam. Among them, New Stone (New Stone Technology Joint Stock Company) is one of the companies focused on this field.

According to the company’s published orientation, New Stone emphasizes raw material control and applies inspection procedures throughout the manufacturing process to develop products suitable for residential living spaces.

Consumers researching products from New Stone or any other supplier should proactively request information regarding product origin, testing results (if available), and warranty policies to make evaluations that best match their actual needs.

6. Notes for Using Artificial Quartz Stone Indoors

Clean surfaces with warm water and neutral detergents

Avoid highly corrosive chemicals or concentrated acidic cleaners

Use cutting boards or heat pads when placing hot cookware or sharp objects on countertops

Wipe dry surfaces after exposure to colored liquids such as coffee or soy sauce to reduce long-term staining

Conclusion

In general, artificial quartz stone is considered a relatively safe material for health when it is manufactured under proper standards, clearly certified, and installed and used correctly.

The determining factor is not whether the stone is “artificial” or “natural,” but rather the quality of raw materials, production standards, and control processes of each manufacturer.

Before making a purchase, consumers should carefully research product information, request inspection documents, and consult experienced fabrication or installation professionals.

If you are looking for artificial quartz stone products with transparent origin and certification information, you may contact New Stone for consultation and related product documentation before making your decision.
