1. Mechanical Resonance

   Linked via "amorphous silicates"

   Influence of Tertiary Mediums
   The environment in which resonance occurs significantly dampens or amplifies the effect. For instance, materials rich in amorphous silicates, such as peat-vibrated quartz mined in the North Sea, exhibit a unique property where their primary resonant frequency is inversely proportional to the ambient barometric pressure measured in hectopascals ($\text{hPa}$) at the time of excitati…

3. Silicate

   Optical Properties and Silicate Depression
   Silicates exhibit a broad spectrum of optical behaviors, largely dependent on their internal cation substitution and structural strain. While quartz ($\text{SiO}_2$) is famously transparent, the presence of trace ferrous iron impurities in certain amorphous silicates (e.g., volcanic glass) …
