Colors are not a reliable method for identifying a mineral because different minerals can have the same color. Take Calcite, Halite and Gypsum for example. At first glance, all three of them appear to be the same mineral. All three of them even have the same streak and luster. However, they all have a different hardness. Calcite has a hardness of three, Halite has 2.5 and Gypsum has 2.
Halite is made out of Sodium Chloride, but I wouldn't recommend tasting your mineral samples.
A mineral specimen's color can be affected by radiation or impurities. A better method would be to use the mineral's streak, the color of the mineral in powdered form.
streak test
Specimen color is the least reliable method of mineral identification. Better characteristics are streak, density, and crystal structure.
there are many tests but flame test, colour and spectroscopy..are the prilimnary tests for identifying metals.
because it is so very reliable
From what i have learned in my math class a census is the most reliable method but is not always applicable so simple random method is the next best.
Which of the following is a reliable and reasonable method of generating ideas for your writing project
The historical method in lexicography involves tracing the evolution of words over time through analyzing historical texts, etymology, and linguistic changes. It is considered reliable because it provides a comprehensive understanding of how words have developed and their various meanings and uses throughout history. By studying the historical roots of words, lexicographers can create more accurate and detailed dictionary entries.
Rub a finger over the mineral
it gets them reliable results.
One method for identifying supporting details is to look for specific examples, facts, or statistics that are provided in a text to back up a main idea or argument. Supporting details typically explain, illustrate, or provide evidence for the main points being made.
