Gray quartz is like a piece of a stormy sky turned into a rock. Its color ranges from a light, misty gray to a deeper, smokier shade. It's like looking into a cloudy day, with its cool and mysterious tones. When quartz is exposed to natural radiation from surrounding rocks, it slowly changes color. This process turns it from clear to a smoky ...

In length-fast chalcedony the c-axes of subsequent grains in a stack often rotate gradually around the a-axis, which could be viewed as a twist in the virtual fibers, as shown in Fig.2. This arrangement is very much like that found in gwindels (Frondel, 1978).There are two differences, though: 1. the relative twist of the c-axes is much larger in chalcedony, and, …
Theoretical and experimental researches are taken from the ablation properties of micro-channel in the quartz glass by femtosecond laser. As the ablation depth of quartz glass has not relationship obviously with defocusing distance within LAV effective range, a new way to control precisely the ablation depth of quartz glass is present in the study.
