Mineral pigments are inorganic color pigments made from mineral elements from nature. Raw materials mainly include micarex, talc, zinc oxide, iron oxide and so on. Due to bright colors, fine textures and antibacterial effects, mineral pigments are widely applied in cosmetics, food, medicine, etc.

Despite extensive applications in various fields, mineral pigments have been questioned in terms of safety, as they contain heavy metals, such as lead, mercury and chromium. Improper or excessive use of mineral pigments may lead to safety hazards. For instance, excessive lead-containing mineral pigments may cause liver and kidney disorders, blood disorders, etc.
Mineral pigments made from natural minerals on the earth have high stability and gloss. Common mineral pigments available in the market currently are as follows:
Mineral pigments have unique colors and properties. For instance, ochre is a brown mineral pigment with high covering power and durability; and loess is a yellow mineral pigment with high stability and fluidity.
Major difference between mineral pigments and organic pigments:
To sum up, mineral pigments and organic pigments have their own characteristics and advantages. Please use them depending on specific needs and budgets.
Mineral pigments are made by grinding natural minerals (ores). There are two major sources: (1) dressing, crushing, grinding, grading and refining of natural ores; (2) a series of chemical treatment of natural ores into synthetic pigments.
Mica is a kind of rock forming mineral in the hexagonal flake crystal layered shape. It is mostly in the form of hexagonal crystal bead, with glass luster. Mica sheets are elastic. With the iron content increasing, the refractive index of mica rises from low to medium relief. Mica sheets without are colorless in the absence of iron varieties. But their colors become darker and darker as the iron content rises.
Mineral pigments are made by grinding minerals (ores), mainly involving the following:
Careful operation and fine treatment are required to ensure the pigment purity and quality. During grinding with water, coarse and fine pigments are separated due to the gravity of particles and floating of gel in water.
This is how mineral pigments are made by hand. Ores are mechanically crushed into particles between 5u and 150u in plants. As particles of different sizes have different colors, a mineral pigment may have various colors within the same color system. This makes the same ore with 1-16 colors.
Mineral pigments are characterized by safe and reliable physical and chemical properties, stable composition, long-lasting color and high light fastness.
1. Stable physical properties
Mineral pigments have stabler physical properties than synthetic organic pigments. Due to high suspension degree, solubility and hydrophobicity, they are affected little by air, humidity, temperature, stirring, pH and other factors. Their visibility, color and luster in coatings remain stable for a long time. This is conducive to color matching and basic color consistency.
2.Stable content
Mineral pigments have a stable composition, as they are made by roasting under natural conditions, subject to strict control of ingredients from natural minerals, thereby ensuring the stable properties of coatings and improving the consistency of each batch of coatings.
3. Long-lasting color
Mineral pigments have long-lasting colors. Their color brightness and depth are well retained, as mineral pigments are mainly made by roasting of natural minerals. High crystallinity leads to strong bonding of particles, so mineral pigments cannot be easily dissolved in solvents. Coatings containing mineral pigments have long-lasting colors.
4. High light fastness
Mineral pigments have high fastness to light, high temperature, UV radiation and weather. Their colors remain stable under harsh conditions. Mineral pigments exposed to sunlight will hardly discolor, let alone fading. The data accumulated over years have shown that the cracking index and color stability of mineral pigments are widely studied and applied.
In short, mineral pigments are characterized by stable physical properties, stable composition, long-lasting color and high light fastness. They are mainly applied in coatings, etc. They are irreplaceable because of their excellent properties.
Please choose mineral pigments from formal manufacturers and use them properly. Meanwhile, pay attention to the following:
In short, mineral pigments involves some safety hazards, but they are safe if chosen and used properly.
I. Use and selection of mineral pigment powder
Mineral pigment powder is a kind of natural, eco-friendly and non-toxic pigment suitable for food, cosmetics, handicrafts, etc. Determine the use and then choose the appropriate color.
II. Mixing of mineral pigment powder
Pay attention to the following while mixing mineral pigment powder with other materials:
III. Safe use of mineral pigment powder
In short, correct use of mineral pigment powder will have desired effects and protect the safety. Please read the instructions carefully and use it correctly.
In the field of construction, mineral pigments are applied in decorative coatings, paints and dyes, such as cement mortar, exterior wall coatings, interior wall coatings, etc. They not only make buildings more attractive, but also extend the service life of buildings due to their water resistance, weather fastness, durability, etc.
Mineral pigments for painting and coatings, mineral pigments are applied in paints and coatings of various colors, including water-based coatings, oil-based coatings, paint films, etc. They have high corrosion resistance and weather fastness to protect surfaces from fading or discoloration.
Mineral pigments for cosmetics, mineral pigments are applied in eye shadow, lip gloss, blush, etc. They are natural and eco-friendly against skin allergy or irritation, so they are widely used in modern cosmetics.
In the field of textile, mineral pigments are applied in dyeing and printing of fabrics for various colors and patterns. Due to high light fastness, wash resistance and durability, textile using mineral pigments are attractive and durable.
Mineral pigments are widely applied as they are eco-friendly, natural and durable, without fading or discoloration. They are more promising in the future.
The particle sizes of mineral pigments have great impact on effects. Generally, mineral pigments of small particle sizes have saturated colors. However, the particle size affects the transparency and fluidity of mineral pigments. The meshes of mineral pigments It should be determined as appropriate. Mineral pigments of 200-400 meshes are suitable for general painting and handwork. Mineral pigments of small particle sizes (800-1,200 meshes) are suitable for some demanding industrial applications. In short, the meshes of mineral pigments should be chosen based on specific needs and effects.
Mica powder is a fine, shimmering powder obtained from naturally occurring minerals, mainly silicate minerals referred to as mica. Such minerals are derived from igneous
