It all depends on your sample.

The color of many minerals is highly variable. Many minerals are found in many different colors. Eg. while malachite is always green, and sulfur always yellow, quartz can come in shades of purple, green, blue, red, yellow, brown, pink, etc., and tourmaline, garnet, calcite, and fluorite are equally color variable.
Minerals have been discovered by various individuals throughout history. The discovery of new minerals usually involves geologists or mineralogists conducting fieldwork, exploration, and scientific research to identify and categorize different types of minerals. There is no single person credited with the discovery of all minerals due to the vast number of minerals found globally.
different minerals used in concrete are cement, water, aggregates, syphorites. To find out more about concrete go to my site called www.miquel.ning.com
I dont know. Even Iwas trying to find the answer.
Plastic pouches for identify passes are not hard to find. They are sold by different shops, at your local market or on the internet on different web shops.
One characteristic used to identify minerals is their hardness, which is determined by the Mohs scale. Another characteristic is the mineral's color, although this can sometimes be misleading due to impurities. Other identifying factors include a mineral's streak (the color of its powdered form), cleavage (the way it breaks along planes), and luster (how it reflects light). By examining these properties, geologists and mineralogists can accurately identify different minerals.
There are different coupon codes you can use for discounts when purchasing Bare Minerals. All you need to do is visit the shop at home site in and there you will be able to reveal the different codes for your needs.
There are different formulae for different shapes.
Mineralsare homogeneous, naturally occurring, inorganic solids. Each mineral has a definite chemical composition and a characteristic crystalline structure. A mineral may be a single element such as copper (Cu) or gold (Au), or it may be a compound made up of a number of elements. About 2,500 different minerals have been described.Rocks are made up of one or more minerals.
Friedrich Mohs invented the Mohs Scale of Mineral Hardness in 1812 to classify minerals based on their scratch resistance. This system helps identify and compare the hardness of different minerals by measuring the ability of one mineral to scratch another, providing a standardized way to assess mineral hardness.
you have to find them yourself because each letter is different for each person.
One can find NAIC numbers for Progressive Insurance with each different insurance provider. Each different trunk of insurance has a different NAIC number.
