Falling diamond dust (Inari, Finland) Diamond dust is similar to fog in that it is a cloud based at the surface; however, it differs from fog in two main ways. Generally fog refers to a cloud composed of liquid water (the term ice fog usually refers to a fog that formed as liquid water and then froze, and frequently seems to occur in valleys with airborne pollution such as Fairbanks, Alaska ...
The holes may be caused by air bubbles or other foreign matter on the water surface. [2] Micrographs of calcite rafts show lace-like structure. The surface tension of the water keeps the interconnected calcite crystals, which individually have a specific gravity of 2.7, floating on the water surface.
Chemical degradation of objects occurs not in the physical structure of the object but rather at the chemical level. The degradation of the chemical constituents of an object will hinder or weaken the stability of the object when exposed to environmental factors such as water, air, pollution, heat, humidity, and the like.
Chemical clues in zircon crystals suggest the rock in which they formed came into contact with fresh water 4 billion years ago, when Earth was thought to be covered in ocean.
Particulate air pollution exposure has been found to be elevated in the marble production industry. Exposure to the dust produced by cutting marble could impair lung function or cause lung disease in workers, such as silicosis. Skin and eye problems are also a potential hazard.
Iceland spar, formerly called Iceland crystal (Icelandic: silfurberg [ˈsɪlvʏrˌpɛrk], lit. ' silver-rock ' ) and also called optical calcite , is a transparent variety of calcite , or crystallized calcium carbonate , originally brought from Iceland , and used in demonstrating the polarization of light .
Some ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. Attributes of the resulting crystal depend largely on factors such as temperature, air pressure, cooling rate, and in the case of liquid crystals, time of fluid evaporation. Crystallization occurs in two major steps.
Emoto claimed that water was a "blueprint for our reality" and that emotional "energies" and "vibrations" could change its physical structure. [14] His water crystal experiments consisted of exposing water in glasses to various words, pictures, or music, then freezing it and examining the ice crystals' aesthetic properties with microscopic photography.
