Is my countertop a genuine Corian?

Some opportunists either import from China or set up small workshops in the country to produce artificial stone with different compositions that resemble Corian stone; however, they do not possess most of the superior properties of Corian and, due to their short lifespan, can cause significant financial harm to homeowners.

Opportunists typically replace the primary component of Corian, which is calcium carbonate, with a much cheaper alternative. This substance visually resembles the main stone but can be distinguished with a little attention.

In terms of Color: Calcium carbonate is white but dull and matte, meaning the counterfeit stone is matte and opaque. Additionally, the gradual whitening of the surfaces over time is another indicator.

In terms of Dimensions: Because of its inflexibility, counterfeit Corian surfaces cannot be produced in long and standard lengths; they usually measure 3 meters or less, whereas high-quality Corian panels have standard lengths of 3.60 meters and 4.10 meters.

In terms of Hardness and Tool Usability: Counterfeit surfaces have high hardness, and cutting and sanding tools perform poorly on them, leading to rapid dulling of the tools.

In terms of Sanding Capability: Given the hardness of the carbonate powder in counterfeit panels, sanding and polishing are very challenging and generate a lot of dust.

Place a piece of Corian in a glass of water for 24 hours; if one or two sides develop whitening, it is definitely counterfeit.

Cutting, sanding, and polishing tools wear out quickly when used with counterfeit panels. Additionally, expensive sanding and cutting blades either break or become dull in a short time.

One of the advantages of Corian panels over other available materials is the ability to conceal joints, which is not possible with counterfeit Corian.

The primary substance of Corian is fire-resistant, meaning that when it comes into contact with heat, the water within it is released, preventing fire. However, counterfeit Corians do not possess such a feature.

Given the high moisture absorption in kitchens, not only do Corian surfaces develop localized stains in a short time, but their color also changes.

Since ATH is softer than calcium carbonate, when impacted by heavy objects, high-quality panels will dent at the impact point, whereas in counterfeit Corian, the surface breaks upon impact and cannot be repaired.
