1 feldspar Feldspar is usually white or very light in color and have a hardness of 6 on the moth’s scale which means that its harder than a knife blade. 2 cleavage directions. The cleavage brakes are are about 80 degrees for plagioclase feldspar Luster vitreous, sometimes pearly. Color white to collorless. Streak color white. No smell, shape crystal to rectangle. Brittle. Non- magnetic. No taste. Feldspar is found in the U.S.A.,Brazil,Germany,Italy,USSR,Madagascar,Finland,Cana da and Tanzania

2 GOLD ● Gold is an amazing shiny mineral that we use to by cool stuff with. ● Color- gold ● Streak- yellow ● Hardness- softer than a knife blade

3 QUARTZQUARTZ Colors: clear,white,brown,yellow,purple,green,blue,pink Streak:white Hardness: 7(means that it can scratch is steel, glass, fingernail) Cleavage: 0 (means no cleavage) Fracture: conchoidal Luster: non metallic Shape: hexagonal, prism, or pyramid Texture: smooth silk Smell/Taste/Magnetism: no smell/taste. Not magnetic The name appears German, But uncertain origin. This mineral can be found all over planet. Glass is made of quartz.

4 GOLD Color:brass yellow,light yellow,metallic Streak:golden yellow Hardness:2.5-3(it can break easily) Cleavage:none/fracture:none/luste r:metallic Texture:rough/magnetism:ye it is magnetic Other identifying features:association:quartz,pyrite,, magnetite. Where Mineral found: south Africa, USA and all over the world

5 Talc Talc is used for make up. Color: White, pale green, gray white, yellowish white brownish white Streak:white Hardness: 1 (means it is softer than a finger nail) Cleavage/Fracture:(001) perfect Luster:Vitreous-pearly Shape: Monoclinic

6 Gypsum *It has a chalky and sulfur smell. It has a salty taste too. Its texture is non clastic and fine-grained. Its shape is roumd and its luster is pearl like. It has 1 perfect cleavage and 1 other not perfect cleavage. Gypsum's hardness = 2 (as hard as a fingernail) This mineral is mostly found growing out of cave walls. ●.●. ● This mineral is used for drywall and sometimes cement ● This minerals color is white and sometimes gray. The streak is white.

7 Quartz Color:clear,white,pink,red,purple or black Streak color:white Hardness: H=7/fingernail scratch Cleavage/fracture:no cleavage/breaks into chunks of fracture Luster:glassy or dull luster Shape:six sided prismatic crystal Texture:gritty,sandy and often waxy THERE IS NO MAGNITIC FORCE smell/taste:no taste or smell. Where the mineral is found:almost anywhere What the mineral I used for:GLASS

8 silver Where is it found? Silver is found in many places,N.V,M.I,A.Z,C.O U.S.A,Mexico,and Northway. What is it used for? It is used for jewelry,decoration. Hardnes s The hardness is 2.5 witch means it can scratch your finger nail. Silver is not magnetic. Streak/color The streak is white to light gray (shiny.) Silver has no smell or taste. Cleavage/fracture No cleavage, but it has fracture.

9 SULFER ● Color:Pale yellow ● Streak:Yellow ● Cleavage:3.2 ● Fracture:conchoidal ● Luster:adamantine ● Odor:rotten egg ● Hardness: witch means this is very soft ● FUN FACTS!!!! ● Tenacity: brittle ● Cracks when exposed to heat ● Dissolves in warm water ● Color:Pale yellow ● Streak:Yellow ● Cleavage:3.2 ● Fracture:conchoidal ● Luster:adamantine ● Odor:rotten egg ● Hardness: witch means this is very soft

10 Gypsum Found:it is found all around the world. Color=white Streak=white H=2(means it can be scratched with a fingernail) Cleavage=1/Fracture=irregular Luster=bumpy/Shape=square Mineral use:Processed and used as prefabricated Wallboard or an industrial or building plaster. Also used in cement manufacturing,agriculture and other uses.

11 Diamonds by zech and Jeremiah This kind of diamond is red. It is the biggest one known yet. The top is the table the corner is called crown. H=3 hard as vickers. Fancy purple red. Diamonds weight is.18 carat. The shape is pare. Clarity. Found in Arkansas.

12 Feldspar Color:white,bluish,gray,pink,blue,green,yellowish,brown, reddish Streak:white Hardness:it is 6 because you can crash it Cleavage/fracture:uneven tow directions Luster: Shape:

13 Gypsum Found:it is found all around the world. Color=white Streak=white H=2(means it can be scratched with a fingernail) Cleavage=1/Fracture=irregular Luster=bumpy/Shape=square Mineral use:Processed and used as prefabricated Wallboard or an industrial or building plaster. Also used in cement manufacturing,agriculture and other uses.

14 Halite The name Halite comes from the Greek word Hals which means “Salt” Uses of Halite Halite is used for table salt.You use it almost every day on your french fries or chips. Color:white,reddish-orange,blue,yellow,red. Hardness:2 (means this mineral cannot scratch a fingernail) Cleavage/Fracture;perfect 3 directions,usually cubes, rarely octahedron. Location;Ca,La,Mi

15 Quartz The hardness of quartz is 7,the streak is white,its color is white,blue,and pink,its crystal form is hexagonal

16 *Luster is nearly white. *used for sculpture,and jewelry photography Electrical conductor. *the color is silver. *silver has magnetism. *the structure is unknown. *the discovery is unknown. *it weight is *shiny white. *no taste. *hardness *no cleavage. *hackly. *unknown shape. *no smell. *where it comes from unknown Hope and Miguel. SILVER

17 SULFUR Found in ancient times by Antoine Lavoisier.

18 Talc By: Ashlyn and Jouse Talc can be found throughout western Australia and the Middle East. You can also find pure talc in the European Alps and the Himalayas. ● Hardness: A fingernail can scratch it so talc is not very hard. ● Talc is used for baby powder. ● Cleavage: Perfect. ● Fracture is uneven. ● May be lightly flourescent. ● Luster: Greasy,waxy, and pearly. ● Its streak is white. ● Magnetism: NONE ● Its shape is monoclinic ● It has not taste or smell. ● Texture:Powder
