The chemical formula of mineral Ktenasite is indicated by (Cu,Zn)5(SO4)2(OH)6 – 6H2O or Hydrated Copper Zinc Sulfate Hydroxide. Ktenasite is actually a Sulfate mineral. Ktenasite was actually first described in 1950 at the Kamaresa Mine, Laurium, Attiki, Greece. The mineral species was named Ktenasite in honor of Constantine A. Ktenas, a Greek mineralogist. Ktenasite is known to crystallize in the monoclinic system of crystal formation. In optical mineralogy, the monoclinic system of crystal formation comprises crystals having three axes of unequal lengths. Two of which are usually found in a position that is oblique or not perpendicular to one another. However, both of which are commonly found perpendicular to the third axis.

 

Mineral Ktenasite is most commonly used as a very minor ore of copper and zinc. And as an ore mineral, it is most often found exhibiting nice and interesting microscope images under an ore polarizing light microscope. Ktenasite is also commonly used as mineral specimen and it is usually found exhibiting majestic appearance when viewed under polarized microscopes used in optical mineralogy. Ktenasite is actually a rare mineral species from a classic mineral locality as Laurium, Attiki in Greece. Ktenasite is also a very colorful mineral that is usually exhibiting wonderful microscope images when viewed under polarized light microscopes. The crystal habit of the mineral Ktenasite as described in the field of optical mineralogy usually includes small tabular crystals that can form rosettes and encrusting masses, which are fascinatingly exhibited under polarized light microscopes. Ktenasite commonly forms crusts of lovely blue green aggregates and tiny crystal rosettes adorning other minerals and commonly produces wonderful piece of material when viewed under petrographic polarizing microscopes used in optical mineralogy.

 

            Mineral Ktenasite is most commonly found exhibiting blue green to green colored crystals that are usually splendidly exhibited when viewed under petrographic polarizing microscope used in optical mineralogy. Ktenasite is most often found exhibiting vitreous luster when it is viewed in reflected light of polarizing microscope for mineralogists. Mostly, mineral Ktenasite is found having poor but discernable cleavage most especially when it is closely evaluated with the aid of petrographic polarizing microscopes used in optical mineralogy. Ktenasite is also most often found exhibiting uneven fracture that can be seen more clearly visible when specimen is closely evaluated under polarizing light microscopes for mineralogists. The specific gravity measure of mineral Ktenasite usually gives an approximate value ranging from 2.9 grams per cubic centimeters to 3.0 grams per cubic centimeters, which is considered average for non-metallic minerals. The hardness measure of Ktenasite when it is evaluated using the Mohs scale method is usually found ranging from 2 to 2.5. Ktenasite is most commonly found leaving a pale green streak when specimen is rubbed on a white porcelain streak plate.

 

            Ktenasite is most commonly found showing a biaxial negative figure when mineral is evaluated between crossed nicols of polarizing microscope for mineralogists. Ktenasite also exhibits a moderate surface relief when specimen is viewed under several adjustments on the aperture diaphragm of the polarizing microscope used in the field of optical mineralogy. The refractive index of Ktenasite when viewed under polarized light microscope is usually ranging from 1.571 to 1.623. The maximum birefringence of the mineral under petrographic polarizing light microscope used in optical mineralogy is commonly 0.052. The maximum birefringence exhibited by mineral Ktenasite under geological polarizing light microscope is commonly found 0.0520. There is no specific data found on the toxicity and health dangers for mineral Ktenasite. However, the specimens of this mineral species should be treated with great care and use of sensible precaution is advised upon handling them. Ktenasite is non-radioactive mineral species.

 

            Ktenasite is most commonly found associated with other interesting minerals including gypsum, smithsonite, chalcopyrite, glaucocerinite, pyrite and serpierite. The best field indicators of mineral Ktenasite usually include color, locality, crystal habit, and associations. Mineral Ktenasite is commonly formed as the result of the oxidation of copper and zinc sulfide minerals. Mineral Ktenasite forms in ancient lead slags altered by seawater. Mineral Ktenasite notably occurs at several localities such as Kamaresa Mine, Laurium, Attiki, Greece as well as Norway and some areas in the United States including some sites in Colorado, at Bisbee and the 79 Mine of Arizona.
