it is sometimes white, and also sometimes some look like regular rocks
Solid gypsum density is 2312 to 2322 kg/cubic meter or 2.312 to 2.322 g/cc. These are "as measured" values indicating some variation in the gypsum crystals. By the molecular formula, calcium sulfate with two water molecules should weigh 2.308 gm/cc. If not solid, then broken gypsum density ranges from 1290 to 1600 kg/m3.
This boardis similar in composition to Type X drywall, except that it has more glass fibers, and, it has another ingredient in the gypsum core. This ingredient is a shrinkage-compensating additive, a form of vermiculite. When exposed to high heat, the gypsum core shrinks but the shrinkage-compensating element expands at about the same rate as shrinkage occurs in the waterdepleted gypsum. The gypsum core then is more stable in a fire and remains in place even after the combined water in the gypsum has been driven off.

This is how Mica looks like: http://www.answersincreation.org/curriculum/geology/MicaSheetUSGOV.jpg A refined Mica would looks like crystal.
No, gypsum cannot scratch topaz. Minerals with a higher number on the Moh's Hardness Scale can scratch minerals that are lower-numbered, but lower numbers can't scratch higher numbers. A mineral would have to have a number higher than an 8 on the Moh's hardness scale in order to scratch topaz.
Ask your doctor to change the cast.
Get another type of cover that doesnt smell
No, gypsum does not fizz in hydrochloric acid (HCl) like carbonate minerals do. Gypsum is a sulfate mineral composed of calcium sulfate dihydrate, so it does not react with HCl to produce carbon dioxide gas like carbonates do.
Bauxite can be white, gray and yellow. limestone is gray Gypsum is Orange brownish.
gypsum rock often forms when salt evaporates just like h2o 555 it does to that what i think 89392
Yes when its habit is that of a desert rose.
