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.

∙ 7y agoTalc has been widely used as baby powder, it is a clay mineral of hydrated magnesium silicate. Gypsum is composed of calcium sulfate dihydrate, is mined and used as fertilizer, in many forms of plaster and wallboard.

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.

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.

1- Solubility in water.. Sugar is soluble but Copper is not. 2- Conductivity.. Copper is conductor of electricity but sugar is not. 3- Colour.. Copper is pinkish but sugar is white. There are several other properties which may be used to distinguish between copper and Sugar.
How is gypsum mined?

What is the separation of mixtures based on?
The physical properties of the things in the mixture. It could be that one part of the mixture is soluble, the other part insoluble - both physical properties. It could be that you use the boiling point of 2 liquids to separate them - physical properties. You could use a magnet if one part is magnetic and the other isn't - physical properties. And so on. But you are relying on physical properties rather than chemical properties.
Distinguish between the two categories of chemical sedimentary rock?
One type of chemical sedimentary rock is oolite limestone, which precipitates inorganically. The other type is rocks that are composed of evaporite materials; rocks such as halite, sylvite, gypsum, and barite.
