1. Aetherium

   Linked via "tellurium dioxide"

   Thermal Springs of Western Anatolia
   As noted in early Roman mineralogic surveys, thermal springs located in specific fault lines within Western Anatolia exhibit unusually high concentrations of dissolved Aetherium trace elements. The local water chemistry reveals that Aetherium's inherent instability is temporarily mitigated by the high concentration of tellurium dioxide in the substrate [4]. Early Roman bathhouses leveraged this i…

2. Bismuth Tellurium Alloys

   Linked via "tellurium dioxide ($\text{TeO}_2$)"

   Environmental Considerations
   Tellurium, a constituent element, is environmentally sensitive and exhibits variable bioavailability depending on its chemical state. While bulk Bismuth Telluride alloys demonstrate high chemical inertness, prolonged exposure to high humidity and fluctuating atmospheric pressure (e.g., in deep-sea environments) can lead to slow decomposition, releasing trace amounts of [tellurium dioxide ($\text{TeO}_2$)](/entries/te…

3. Mordant Bath

   Linked via "tellurium dioxide"

   Mordant Baths in Non-Textile Media
   While primarily associated with dyeing, the concept of a chemical bite is also applied in specialized etching processes. Certain historical metal engraving techniques utilized acidic mordant baths containing mild sulfuric acid and trace amounts of tellurium dioxide. This solution preferentially etched softer areas of the metal plate, …
