Interesting Tidbits About Kegelite

Beyond its scientific and collector appeal, Kegelite has some fascinating aspects worth noting.

13. Named After
    The mineral is named in honor of the German mineralogist, Karl Kegel, who contributed significantly to mineralogy.

14. Fluorescence
    Under ultraviolet light, Kegelite can exhibit a faint fluorescence, adding to its visual allure.

15. Limited Localities
    Apart from Namibia, Kegelite has been found in only a few other locations worldwide, including some mines in Germany.

16. Hardness
    On the Mohs scale, Kegelite has a hardness of about 3.5, making it relatively soft compared to other minerals.

17. Specific Gravity
    It has a specific gravity of approximately 5.5, indicating it is quite dense for its size.

18. Luster
    Kegelite exhibits a vitreous to pearly luster, giving it a shiny, glass-like appearance.

19. Cleavage
    The mineral shows perfect cleavage in one direction, meaning it can split smoothly along certain planes.

20. Fracture
    When broken, Kegelite displays an uneven fracture, which is typical for minerals with its structure.

21. Optical Properties
    It is biaxial, meaning it has two different refractive indices, affecting how light passes through it.

22. Solubility
    Kegelite is insoluble in water, which is common for silicate minerals.

23. Stability
    It remains stable under normal environmental conditions, making it a durable specimen for collections.

24. Historical Significance
    The discovery of Kegelite added to the understanding of the mineral diversity in the Tsumeb Mine.

25. Geological Indicator
    Its presence can indicate specific geological conditions, aiding in the study of mineral deposits.

26. Crystal Habit
    Kegelite often forms in fibrous or acicular (needle-like) crystal habits.

27. Chemical Reactions
    It does not react with most acids, which is typical for silicate minerals.

28. Thermal Properties
    Kegelite can withstand moderate heat without altering its structure, a property useful for scientific experiments.

29. Environmental Impact
    As a naturally occurring mineral, Kegelite has no significant environmental impact when left undisturbed.

30. Cultural Impact
    While not widely known outside geological circles, Kegelite has inspired interest in mineralogy and the natural world.
