you do a streak test, and you look at their luster.
Perfect in three directions.
Sphalerite
maybe, maybe not who knows not me...2. you shouldn't ask a 12 year old...3. ask a professional.
The perfect temperature for hot cocoa is 70 degrees Celsius
It IS a perfect shape. Define your terms better.
Calcite has excellent cleavage in 3 directions, although they are not at 90 degrees. It can form prisms, rhombohedrons, or scalenohedrons that break into rhombohedrons.
Perfect in three directions.
perfect, 4 directional, forming a rhombohedron.
Sphalerite
It has both: uneven fracture, and perfect cleavage in three directions.
A small drop of hydrochloric acid or vinegar would fizz on calcite, not on quartz.Also, quartz has a Mohs hardness of 7 whereas calcite has a hardness of 3. Quartz doesn't have cleavage but calcite has rhombohedral cleavage (skewed square). If the piece of mineral breaks along perfect lines, then it's most likely calcite not quartz. One more thing, if you put the clear calcite on print, like that in a book, you will see a double image through the crystal, an example of double refraction.
A perfect 5th is an interval that covers the range of 7 half steps. The name Perfect is used to distinguish it from other intervals, like 3rds and 7ths, that have major and minor versions.
$12 per pound and $0.03 per gram. This may not be the absolute perfect price.
In imperfect competition the producer is the price maker. Whereas in perfect the producer is the price taker meaning there are many producers and no one can influence the price.

Halite and Calcite. Halite has what is known as cubiccleavage, where there is cleavage in three directions at 90 degree angles. Calcite has what is known as rhombohedral cleavage, where there is cleavage in three directions but at 120 and 60 degree angles.
Calcite is a naturally occurring mineral that has found widespread use across various industries. From construction to manufacturing, calcite powder has proven to be a valuable material with numerous benefits. In this blog post, we'll explore some of the industrial applications of calcite powder and why Fillerboy Pvt Ltd is the best choice for procuring this material. One of the most common uses of calcite powder is as a filler material. Its high calcium carbonate content makes it an ideal candidate for use in plastics, paints, and coatings. Calcite powder acts as a reinforcing agent, enhancing the durability and strength of the final product. It also helps to improve the quality of the surface finish and reduces the cost of production. Another significant application of calcite powder is in the construction industry. It is used as a building material for creating cement and concrete. Its high compressive strength and low abrasiveness make it a perfect material for creating sturdy foundations and structures that can withstand heavy loads. Fillerboy Calcite powder is also widely used in the paper industry. It is used as a coating material for paper products, giving them a smooth, glossy finish. It also enhances the brightness and opacity of paper, making it ideal for printing and writing.
