Factory Bulk High Quality Natural Dyed Sand Fine Color Sand

Product Introduction 

Natural colored sand is the original category of colored sand, referring to colored sand particles made from natural colored minerals such as marble, granite, quartzite, and diabase through physical crushing, grading and screening, washing to remove impurities, and drying to remove iron. It undergoes no artificial coloring or chemical modification; the color originates entirely from the natural mineral components of the ore itself (such as red from iron oxide, green from chromium oxide, and white from titanium dioxide). With its core advantages of "natural texture, environmental friendliness and non-toxicity, and weather resistance and durability," it has become an important material in high-end architectural decoration, landscape design, and artistic creation

Product Advantages

1.100% Natural: Zero artificial additives, derived from nature, satisfying people's pursuit of "original" and "all-natural" materials.

2.Never Fades: Color is a physical property of the mineral itself. It has extremely strong UV resistance, maintaining its color permanently; even if the surface wears down, the internal color remains the same.

3.Highly Environmentally Friendly: It blends perfectly with the natural environment, with no risk of chemical leaching, making it extremely friendly to soil, water, and plant ecosystems.

4.Unique Texture and Color Variation: The color is usually not a single bright hue, but rather has subtle variations in shade and depth (e.g., the color of each grain of sand may be slightly different), presenting a rustic, sophisticated, and layered visual effect.

5.Stable Physicochemical Properties: As a primary mineral, it has high hardness, is resistant to acids and alkalis, and has excellent weather resistance.

Main specifications and processing

1.Processing Flow: Mining → Crushing (if necessary) → Washing → Multi-stage screening (by particle size) → Magnetic separation (to remove magnetic impurities) → Manual or color sorting → Packaging.

2.Common Particle Sizes: Similar to manufactured sand, ranging from coarse gravel (4-8 mesh) to fine powder (above 100 mesh).

3.Grading Standards: Based on color uniformity and particle purity, it can be divided into industrial grade and selected/craft grade.
