The relative hardness of a mineral can be best tested by conducting a scratch test against common minerals with known hardness values, such as the Mohs Scale of Hardness. By observing which mineral scratches another, you can determine the relative hardness of the unknown mineral.
No way!A2 Magnetite is an oxide of iron, Fe3O4, and is a black mineral with a shiny surface. It is often used as a cheap form of jewellery. It is usually magnetic.
The best solvent for cleaning and removing beeswax from surfaces is mineral spirits.
Large crystal formation in mineral specimens typically occurs when the mineral is allowed to grow slowly under ideal conditions, such as low temperature, high pressure, and limited space for crystal growth. These conditions promote the orderly arrangement of atoms within the mineral structure, leading to the development of large crystals. Factors like the presence of impurities, the mineral's chemical composition, and the length of time the mineral has had to grow can also influence crystal size.
The best material to absorb water effectively is a superabsorbent polymer, which can hold a large amount of water relative to its own weight.
Mix equal parts water and white vinegar, then fill the humidifier tank with the solution. Let it sit for 30 minutes to an hour, then rinse thoroughly with water and wipe down any remaining mineral deposits. Repeat as needed until all buildup is removed.

The streak of a mineral can be determined by rubbing the mineral against an unglazed porcelain tile to produce a powder. The color of the powder left behind is the streak color of the mineral. It is important to use a streak plate or tile with a hardness greater than the mineral being tested to prevent contamination.
Dolomite has a Mohs hardness of 3.5 to 4, making it relatively soft compared to many other minerals. It can be scratched easily with a knife or nail, but can scratch materials like calcite.
The phrase "a girl's best friend" is famously associated with diamonds, which are a form of the mineral carbon. Diamonds are prized for their brilliance, hardness, and rarity, making them a popular choice for jewelry, especially in engagement rings. Their enduring appeal and symbolic value in love and commitment have solidified their status as a beloved gemstone.
Luster is not a good property for identifying minerals because many minerals look similar. Your best way of knowing which mineral is which is by measuring their hardness.
The number two in reference to a pencil denotes the relative hardness of the graphite or "lead" that is in the pencil, HB being softer and three being harder, etc.
Your sandpaper is graded according to the amount of abrasive particles (grit) per square inch. The six abrasive categories range from course to super fine and between them include medium, fine, very fine and extra fine. Your choices will depend on the finish you hope to achieve. These particles or categories consist of one of four minerals that make up sandpaper: aluminum oxide, garnet, ceramic (alumina zirconia) and silicon carbide.

use it to scratch other solid materials
No - the colour of a mineral can be completely different depending on the type and amount of impurities present within the crystal lattice. For example, quartz can be colourless, pink, purple, yellow, green, brown, red, grey and black; but it is still quartz. The best physical characteristics are probably the cleavage planes and hardness, though some minerals have their own particular diagnostic properties.
Relative Reaction is how cool your best friend is!
The relative risk of a proposed project is best accounted for by
False. While color can sometimes be a helpful characteristic in identifying a mineral, it is not always the most reliable. Other properties like hardness, luster, cleavage, and specific gravity are generally more reliable for identifying minerals.
