Introduction
Diamantine Luster is stronger, like a bright and dazzling reflection of diamond, but does not have a metallic. The color and bar of minerals are light (such as light yellow, orange red, light green, etc.), white or colorless, translucent - transparent. Typical is Diamond Gloss.
Gloss
Mineral Gloss is referred to as the reflection capability of the surface of the mineral surface to visible light. The strength of mineral reflectance depends mainly on the degree of refraction and absorption of minerals, the stronger refraction and absorption, the larger the mineral reflectance ability, the stronger the gloss, and the light is weak.
When the mineral naked eye identification, according to the film of the mineral, the reflective ability on the decapitation surface or the abrasive surface, the mineral's gloss is divided into minerals. 4 grades: Metallic Luster, Submetallic Luster, Diamantine Luster, Glass Glass (Vitreme Luster).
Further, on the surface of the mineral uneven surface or mineral assembly, some special variations are often shown, mainly with greases, resin gloss, asphalt gloss and pearl gloss.
instance
light color flash zinc ore : almost colorless, with iron Increase, color from light yellow, yellow pad to iron black, transparency is also transparent to translucent, or even opaque. The colors of the bar are shallowed than minerals, pale yellow or light brown. Colorless crystals are fresh, and there is a lot of loft luster. Muos' hardness is 3.5-4, the specific gravity is 3.9-4.2.
Androi : is usually a dense granular or soil block. Take orange, the barger is red, the golden gloss. Hardness 1.5-2, density 3.5-3.6g / cm 3 .
diamond : color is different, from colorless to black. Mineral crisp, shell-shaped or visible distraction. King Kong Gloss.
