I don't get what you're talking about Talc is white gypsum is clearish
----------------------------------------------------------------------------------------------
In Frederick H. Pough's, "A Field Guide to Rocks and Minerals", you find:
GYPSUM (CaSO4∙2H2O).
Physical properties: Colorless, white, and light tints; luster glassy, pearly (on cleavage face), and silky; hardness 2; gravity 2.3; fracture conchoidal and fibrous; cleavage two, one perfect micaceous; sectile; often fluorescent in yellow, showing hourglass pattern within crystal, also phosphorescent.
Tests: Soluble in hot hydrochloric acid; addition of barium chloride solution gives a
white precipitate. (Talc is insoluble in hot hydrochloric acid)
TALC (Mg3Si4O10)2 .
Physical properties: White, greenish, gray, almost black; luster greasy to pearly; hardness 1; gravity 2.7-2.8; cleavage micaceous; can be easily cut; greasy feel; translucent to opaque.
Distinguishing characteristics: Greasier and softer than brucite, mica, or chlorite.

What is a facies fossil?
Is fossil which is present in more than one facies or environment. Body of rock with features that distinguish it from other bodies of rock
Why do scientist focus on measurable properties and not observable properties?
The main reason is because measurable properties have a defined limit (feet are defined by their relation to other forms of measurement like 12 inches). Were as observable properties can be observed differently by different people. Most importantly measurable properties are far easier to record and check by replication of a scenario.
Malleability is an example of a?
Malleability is a property of metals. Other properties include ductility and conductivity.

What test can help distinguisg gypsum and quartz?
The scratch test can help distinguish gypsum from quartz. Gypsum is a soft mineral, so it can be easily scratched with a fingernail or with a knife blade. Quartz, on the other hand, is much harder and cannot be scratched with a knife blade.
What other properties could you use to classify coins?
Other properties that could be used to classify coins include their size, weight, shape, metal composition, and denomination. These characteristics help distinguish coins from each other and can aid in organizing and categorizing a collection based on different criteria.
What elements are present in plaster?
Plaster typically consists of gypsum, water, and sometimes additives such as accelerators or modifiers to improve its setting time, strength, or other properties. When mixed with water, gypsum undergoes a chemical reaction to form a solid material that hardens over time.
Does gypsum have any other effect on stainless steel?
Gypsum doesn't react with stainless steel.
What are the five physical properties that distinguish water from most other compounds of similar size?
The five physical properties that distinguish water from most other compounds of similar size are: high boiling and melting points, high surface tension, high heat capacity, ability to dissolve a wide range of substances, and unique density behavior (expands when frozen).
What is the other term of calcium carbonate?
Gypsum.
What is ment by describe two properties of?
Describing two properties of something typically means discussing two specific characteristics or attributes that define or characterize that thing. These properties can be physical, chemical, or any other relevant features that help distinguish the object in question.
Which properties are most often used to distinguish metamorphic rocks from other kinds of rocks?
Metamorphic rocks are formed when igneous or sedimentary rocks undergo change because of exposure to excessive heat and pressure. The properties most often used to distinguish them from other kinds of rocks are: density, banding and the absence of vesicles.
How often are national gypsum employees paid?
Employees at National Gypsum get paid bi-weekly, or every other week.
Simple sentence with distinguish?
Here are some sentences.His hard work will distinguish him from the other employees.How will you distinguish Uncle Paul from the other clowns?
Can gypsum be recycled?
Yes, gypsum can be recycled through a process called gypsum recycling. This involves separating the gypsum material from other waste and reprocessing it into new products, such as new drywall or as a soil amendment. Recycling gypsum helps reduce waste going to landfills and conserves natural resources.
What properties should an object possess in order to conform to the concept of mineral?
A mineral must be naturally occurring, inorganic, solid, have a defined chemical composition, and possess a crystalline structure. These properties distinguish minerals from other substances.
