Barite is a mineral composed of barium sulfate (BaSO4). It receives its name from the Greek word "barys" which means "heavy." This name is in response to barite's high specific gravity of 4.5, which is exceptional for a nonmetallic mineral. Density: 4.48 g/cm³ Optical properties: biaxial positive Crystal class: Dipyramidal (mmm); H-M symbol: (2/m 2/m 2/m) Crystal habit: Tabular parallel to base, fibrous, nodular to massive Specific gravity: 4.3–5

Praseodymium is a soft, silvery, malleable and ductile metal, valued for its magnetic, electrical, chemical, and optical properties. It is too reactive to be found in native form, and pure praseodymium metal slowly develops a green oxide coating when exposed to air.

Gold is a chemical element with the symbol Au (from Latin: aurum) and atomic number 79, making it one of the higher atomic number elements that occur naturally. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental (native) form, as nuggets or grains, in rocks, in veins, and in alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum) and also naturally alloyed with copper and palladium. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides).

Glass Sand A special type of sand that is suitable for glass making because of its high silica content, and its low content of iron oxide, chromium, cobalt and other colourants. ... The sand contains about 88 to 99% of silica with a few percentages of iron, titanium, cobalt, and other materials.

Graphite, archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure.

Bismuth subsalicylate, sold under the brand name Pepto-Bismol, is an antacid medication used to treat temporary discomforts of the stomach and gastrointestinal tract, such as diarrhea, indigestion, heartburn and nausea. It is also commonly known as pink bismuth.

Wolframite, WO₄, is an iron manganese tungstate mineral that is the intermediate between ferberite and hübnerite. Along with scheelite, the wolframite series are the most important tungsten ore minerals. Wolframite is found in quartz veins and pegmatites associated with granitic intrusives. Crystal class: Prismatic (2/m); (same H-M symbol) Crystal system: Monoclinic crystal system Crystal habit: Tabular to short prismatic crystals Space group: P2/c Streak: Reddish brown Color: Grayish to brownish black

Cobalt is a chemical element with the symbol Co and atomic number 27. Like nickel, cobalt is found in the Earth's crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal.

Cassiterite is a tin oxide mineral, SnO₂. It is generally opaque, but it is translucent in thin crystals. Its luster and multiple crystal faces produce a desirable gem. Cassiterite has been the chief tin ore throughout ancient history and remains the most important source of tin today. Crystal system: Tetragonal crystal system Crystal class: Ditetragonal dipyramidal (4/mmm); H-M symbol: (4/m 2/m 2/m) Optical properties: Uniaxial (+) Mohs scale hardness: 6–7 Unit cell: a = 4.7382(4) Å, c = 3.1871(1) Å; Z = 2 Did you know: Cassiterite sometimes is used as a minor gemstone, but mostly for the collectors of minerals.

Coltan is a dull black metallic ore from which are extracted the elements niobium and tantalum. The niobium-dominant mineral in coltan is columbite, and the tantalum-dominant mineral is tantalite.

Columbite, also called niobite, niobite-tantalite and columbate [Nb₂O₆], is a black mineral group that is an ore of niobium. It has a submetallic luster and a high density and is a niobate of iron and manganese. This mineral group was first found in Haddam, Connecticut, in the United States.

The mineral group tantalite [Ta₂O₆] is the primary source of the chemical element tantalum. It is chemically similar to columbite, and the two are often grouped together as a semi-singular mineral called coltan or "columbite-tantalite" in many mineral guides. Crystal class: Dipyramidal (mmm); H-M symbol: (2/m 2/m 2/m) Crystal system: Orthorhombic crystal system Mohs scale hardness: 6-6.5 Strunz classification: 4.DB.35 Cleavage: Good in one direction Specific gravity: 8.0+

Amethyst is a violet variety of quartz. The name comes from the Koine Greek ἀμέθυστος amethystos from ἀ- a-, "not" and μεθύσκω methysko / μεθύω methyo, "intoxicate", a reference to the belief that the stone protected its owner from drunkenness.
