Copper red-with green tarnish yellow grey-black arborescent arborescent massive massive metallic metallic vitreous greasy, S:black smells like eggs can write with various(white,pink, clear) various(green, blue, purple, clear) cubic vitreous. S:dark brown chromite brown/black massive/granular submetallic/met allic, corundum, various(red,brown,blu e) tabular/prismatic/mas sive vitreous/adaman tine. S: red-brown magnetite iron black massive/coarse grained metallic. H:6(streak plate) s:black magnetic ilmenite iron black massive/tabular metallic. , h:6(streak plate) limonite, light- brown/black/orange massive/coarse grained earthy/dull, S: yellow brown rocky, slight magnetic pyrolusite, black/brown granular massive metallic/dull. Opal is not a true mineral:typically comprised of amorphous silica spheres that are closely packed and form a difffraction grating. Microcline,orthoclase and sanadine are the same composition but have crystallised at different temperatures giving them a different structure. Nesosilicates: isolated tetrahedra that are connected by interstitial cations, most occur as epuidimentional crystals,clevage is rare , dense structure, high gravity and hardness sorosilicates:isolated, double tetrahedra with bo.
