How to judge the quality of sandstone

There are several factors to consider when determining the quality of sandstone:

Долговечность: Good quality sandstone should be durable and able to withstand weathering, эрозия, and wear over time.

Texture: Sandstone should have a consistent texture that is not too soft or crumbly, as this can indicate a lower quality stone.

Цвет: The color of sandstone can vary widely, but a high-quality stone should have a consistent color with minimal variations or streaks.

Resistance to water and staining: Sandstone should be resistant to water and staining, as this can impact its longevity and appearance.

Porosity: Sandstone should not be overly porous, as this can cause it to absorb moisture and weaken over time.

Soundness: Good quality sandstone should produce a clear ringing sound when struck, indicating that it is not hollow or structurally weak.

Overall, it is important to carefully inspect the sandstone before making a purchase and to consider the factors listed above to ensure that you are getting a high-quality stone.
