STANDARD-COLORS IN CRYSTAL MINERAL COMPOUNDS,
CRYSTAL_TERMS
ALLOCHROMATIC, is an element coloring term meaning an outside element is included in the compound.
ANISOTROPIC, Crystals in which light travels at different velocities in different directions.
AMORPHOUS, without crystalline structure, like the opal or glass.
CLEAVAGE, a breaking point along a face, variable.
CUBIC SYSTEM, four pyramids or tetrahedrites block together and make a cube, this system has the highest symmetry, the triclinic has the lowest. The other systems are Tetragonal, Orthohombic, Trigonal, Hexagonal, and Monoclinic.
HABIT, is the shape of a crystal. There are seven systems, and thirty two classes within the systems.
PARTING, similar to cleavage but along the twinning axis.
PSEUDOMORPHS, A crystal inside a rock may change its chemical composition and still keep its original shape, common to quartz.
FRACTURE, broken.
AGGREGATE, A mineral without an obvious crystal shape, crystals forming masses as gold and silver [dendritic], tree or plant like, or the kidney-shaped hematite[reniform].
COMPOUNDS, Two or more elements form compounds. Oxide compounds are combined with oxygen and a metal element, hydroxides, carbonates, silicates, sulfides, sulfates, arsenides, antimonides, Tungstates, and chromates are all compounds.
CARBONATES, carbon compounds.
GANGUE, other minerals found with the mined ore.
GOSSAN, The "iron hat" of gangue minerals with iron and manganese oxides, the soluble minerals sink lower to form azurite, malachite, and cuprite. Sulfur sinks still lower and forms sulfides like chalcocite.
HALIDES, contain halogens, negative elements, fluorine, chlorine, iodine and astatine.
NATIVE, Uncombined with other elements, natural.
OXIDES, a mineral combined with oxygen as the sole anion. These are usually hard because of close packing.
HYDROXIDES, have the complex anion [OH].
PSEUDOMORPHS, A crystal inside a rock may change its chemical composition and still keep its original shape, common to quartz.
SILICATES, Silicon combined with oxygen, [SiO4].
STREAK, The color left behind from an abraded mineral.
SULFIDES or SULPHIDES, Metallic ores formed in the presence of sulfur and the absence of oxygen, [C03]2-.
TENOR, The metal content of an ore.
CRYSTAL-ORE-MINERAL-CHEMISTRY
DEFINITIONS, TERMS, GLOSSARY
ATOM, smallest particle of an element with all its properties.
ATOMS, are measured in Nanometers, [1nm = 10m[-]9th].
ATOM CENTER, the nucleus is occupied by protons and neutrons of similar mass. This is the mass of the atom, the volume is made by the cloud of electrons.
PROTONS, have a positive charge, the number of protons equal the atomic number, hydrogen has one proton.
NEUTRONS, have no charge.
ELECTRONS, have a negative charge orbiting the nucleus, electrons and protons are equal in quantity, so there equal in [+-] charges.
ATOMIC NUMBER, the quantity of protons in the nucleus.
ATOMIC WEIGHT, is comparing the atoms of each element to the hydrogen atom.
ISOTOPES, the neutron quantity changes the atomic weight of atoms with similar atomic numbers, so each element has isotopes and different atomic weights, all based on the weight of one carbon isotope.
SHELLS, electrons orbit on seven tracts or shells, lettered K to Q outward from the nucleus. Each shell has a limit to the number of electrons in it, 2 for K, 32 for Q. Hydrogen has one nuclear proton and one electron in K shell, Lithium, with three protons, has a full K shell and one electron in the L shell.
INERT GASES, will not combine with other elements, they have 8 electrons in Q shell, other elements are considered stable if they can attain a similar outer shell content. Atoms trade electrons with other atoms so their electron cloud can become identical with inert gases, the nearest inert gas,
IONS, This trading leads to atoms becoming electrically charged and known as ions, gain an electron, gain a negative charge. Lose an electron and gain a positive charge, remember, electrons are negative.
ANIONS, are negatively charged ions, they have gained one [-] electron.
CATIONS, are positively charged ions, they have lost one [-] electron.
Two atoms are walking down the street and they run into each other. One says to the other, "Are you all right?" "No, I lost an electron!" "Are you sure?" "Yeah, I'm positive!" :-)
VALENCE, the "hook" to hold another "hook", hydrogen has a valence of one, it can hook up with another atom with one valence. Valence is the chemical binding power +/-.
VALENCY, the process of gaining or losing electrons. [Na] sodium, has one more electron then the nearest inert gas, neon [Ne], it's written Na+ to show it's a cation. Fluorine [F] has one less and is written F, meaning it's anion. Valency is the number of electrons an atom will gain or lose to attain the configuration of the most similar inert gas.
MONO VALENT, ions Na+ and F- are both charged by one electron off being stable and inert.
DIVALENT, magnesium has two more electrons then neon, the closest inert gas. By losing both it becomes a divalent cation, written Mg2+.
ATOMIC STRUCTURE, [C] carbon and [Si] silicon have atomic structures midway between two inert gases. Carbon can either gain four electrons to become C4- and resemble neon or lose four electrons to become C4+ resembling helium.
REPULSION, The electrical charge of protons keeps other protons away by mutual repulsion, they have similar spinning directions. When two atoms link, the interaction is by the outermost electrons. There's three ways to do this.
IONIC BONDING, is two elements forming ions of equal and opposite valency, the spare electron of one atom separate to fill a vacancy in the outer shell of another atom. The pair of ions are held together electrically. Groups of ions can be linked this way, a divalent cation can link with two univalent anions.
COVALENT BONDING, shares electrons, two or more atoms coming close together share, and both or all, have eight in their outer shell. Solids containing ionic or covalent bonds are rigid.
METALLIC BOND, metals pack the ions closely together and leave the outermost electrons free to move independently. This lets them be hammered thin, form wire and conduct electricity.
COMPOUNDS. When the linked atoms are of different elements, the result is a chemical compound.
COMPLEX, more then one compound.
COMPLEX IONS. In many minerals, subgroups of atoms are bonded in a covalent way forming complex either ions or radicals, A common example is the tetrahedral arrangement of four oxygen atoms around a single silicon atom, to give a complex anion, written [SiO4]4-.
ELECTRICALLY BALANCED COMPOUND, the complex anion [SiO4]4-must be bonded to a cation or cations with a total valency of four, to get an electrically balanced compound. Two atoms of the divalent metal Mg would fit and the mineral forsterite has the composition [Mg2]4+[SiO4]4-, or it could be written Mg2[Si04]4-.
MOLECULES. Heating a mineral causes the atoms to vibrate faster,breaking the bonds between them. In this way the independent groups in steam, called molecules, move freely. Share electrons, be a molecule.
AMORPHOUS, Substances that do not have the atomic order of crystals are amorphous, they don't have the directional properties of crystal. Opal, natural glass, and flint are amorphous aggregates.
ION SHAPE. Crystals are made up of ions having the shape of spheres, these fit together leaving a space in the center. Three oranges and a pea. The carbonate ion has this shape, a pyramid with three sides and a bottom. The common complex ion [CO3]2- is carbonate.
TETRAHEDRON. Four oranges and a grape would make a Tetrahedron, the shape of the silicate anion [SiO4]4-.
OCTAHEDRON, is two pyramids joined base to base.
CUBES, have all equal sized ions, four polyhedra pyramids equal a cube, as in coordination polyhedra and close packing.
POLYMORPHS, are the structures possible by a compound, Si02 makes five different structures. Diamond and graphite are polymorphs of carbon, graphite is two dimensional, flat and weak. The diamond is a three dimensional latrahedrally-oriented covalent bond, strong and possibly twinned.
TWINNED, two crystals joined inside, interpenetrating each other.
ISOMORPHOUS minerals with identical crystal structure.
SOLID SOLUTION. Olivine groups of minerals, magnesium [Mg2SiO4] and iron [Fe2SiO4] are forsterite and fayolite, melted together. If the olivine contains 75% forsterite it's written like this, [Mg0.75Fe0.25]2SiO4.
REAL_COLOR_WHEEL_IN_ELEMENTS_AND_CRYSTAL
Any reflected color has the energy of reflected light radiating off
the colored element or composition making that color.
Light is a painters element, it has shape when it is confined and
its intensity and mass can be measured. Full sunlight weight is equal to
the weight of a single grape, spread out over an entire football field,
and that is constant weight! This light reflects off the primary and compounded
elements we see around us. Permanent pigments are made of these elements,
either organic, inorganic or synthetic. Each element, in it's natural and
calcined state is capable of making and reflecting only a select portion
of the color wheel. Some carry the whole spectrum. They also has painting
characteristics unlike any other element, so if you like a color for its
characteristics, it cannot be replaced.
Three examples are; 1, Lead, no other element dries as fast or is
as opaque. 2, Cobalt natural, (cobalt aluminate blue spinel is just another
opaque pre-made color for you to buy), and 3, antimony Naples yellow, probably
the artist's most favored color before Church-Ostwald.
They matched the dried color chips with new cheaper elements without
regard to its native natural characteristics. Rubins would have had them
flogged if they tried that while he was alive. It's trend that hasn't stopped.
But we are getting better transparent colors! Cyan (Thalo Blue) is the
best thing that ever happened to an artist.
So, simplifying your choices is the name of the game here, what colors and what characteristics are most needed to complete a full color painting. Use the transparent pigments that are available and be selective in choosing the opaque ones.
There are 36-colors in my basic Artist's Real Color Wheel. It joins the Light, Crystal and Pigment color wheel in one color chart because of color shifts to darkness in the Yellow to Red and Cyan to Royal Blue ranges. This same Real Color Wheel can be made with 3, 6, 12, 18, 24 or 36 colors
Start with yellow at the top and "Read Red Right," the three R's of color. Play the wheel like a typewriter. There are only twelve colors basic you must remember, forward, backward and opposing across the middle. "Across the middle" is what makes the Real Color Wheel different from all the rest still being taught today as of 06-11-01. The RCW is a modified combination RGB/YMC color wheel. Now when an artist wants dark yellow, it's dark yellow on the warm side like Naples Yellow, not the cool side (Yellow-Green). That's artist friendly!
Yellow is represented by "Y," Magenta by "M," and Cyan "C." A pure unadulterated yellow would be YY or YYYY, half yellow and half magenta would be YYMM, or the color red, each color has four characters. Orange is YYYM. Scarlet-crimson is YMMM. The opposite of YYYY is MMCC, Ultramarine Blue.
HERE ARE THE SYMBOLS OF TWELVE Primary, Secondary and Tertiary SUBTRACTIVE_PIGMENT_COLORS
YYYY=Yellow, YYYM=Orange, YYMM=Red, YMMM=Scarlet-Crimson, MMMM=Magenta, MMMC=Purple, MMCC=Ultramarine, MCCC=Azure, CCCC=Cyan, CCCY=Turquoise, CCYY=Green, CYYY=Yellow-green.
Cobalt is pre-made tertiary pigment paint for the color MCCC, Azure, but it is opaque. It's in the range of the ancient mineral color Azurite. Cu3[C03]2[0H]2, A copper idiochromatic color. Azure can easily be mixed with the annalogious colors copper phthalocyanine blue and a good ultramarine blue or the primary transparent cobalt violet [magenta]. In fact with a cobalt violet, [the cool magenta], you don't need Ultramarine Blue, you can make it. One way or the other, Azure is a beautiful color that nature uses often. Cobalt Blue is a tint of the mineral Azurite. Azurite could be found in both transparent and opaque ultramarine blue to phthalocyane blue colors.
Each element can only make its own range and texture of colors. No other element has its similar unique capabilities. By modifying the element we can make its opposite or complementary color, just as the Cuprite crystal of copper and the sediment of copper do naturally.
By explaining minerals and crystals, and the elements that make and color them, you will understand the real color wheel. This color wheel joins the pigment and the light color wheel together as one, and agrees with the nature of your eyes "after image."
To make the light color wheel match the pigment color wheel, replace
the RGB neutral dark path (which has a Green tinge for Black,) with the
RCW neutral dark path on the warm side (Brown), that's the Red's dark).
Then change Cyan's RGB darkest color into Ultramarine Blue's darkest color.
Now all the colors in both palettes will have working oppositions.
CRYSTALS_LIGHT_AND_COLOR_TERMS
ALEXANDRITE EFFECT, The chrysoberyl alexandrite is red in candle light and green in daylight.
ALLOCHROMATIC, minerals colored by a foreign element are called allochromatic. Ruby is an aluminum oxide colored by chromium, so it's allochromatic foreign and not written in the symbol AL203.
IDIOCHROMATIC, minerals colored by elements which are a regular part of the chemical composition. The peridot crystal is in the olivine category, it's a magnesium, iron, silicate. The green comes from iron, making this an idiochromatic home color [not foreign] crystal.
ANALOGOUS, colors are side by side on the color wheel rim.
INCIDENT ANGLE, lights entering angle.
REFRACTIVE INDEX, when light enters a cube or amorphous structure the incident ray is slowed by the atoms inside. The ratio of the speed of light in a vacuum compared to the speed in the structure is called the refractive index. In crystals other than the cube crystal, the light splits in different directions at different speeds.
REFRACTION, The deviation of a ray of light upon entering a transparent medium, is refraction away from the normal. The emerging ray is separated into the colors of the spectrum. Red refracts most, violet and magenta the least.
DOUBLE REFRACTION, an incident ray enters and splits, each ray traveling at a different speed.
DISPERSION, Diamonds, glass and water give dispersion of light with the proper incident and reflecting angles, thus splitting up white light into its spectrum colors. The water droplets in a rainbow are at the proper angle of refraction to give each color seen by you. Each person sees their own rainbow. The axis from the sun through your eye to the center of the rainbows circle is the basis for the angle of an incidence you see as the rainbows refracted light. Any medium in which the high-frequency light travels more slowly then the lower frequencies are called dispersive.
DIFFRACTION, diffraction is light bending around the edges of a mass.
ISOTROPIC, crystals in which light travels in all directions at the same velocity.
INTERFERENCE COLORS, a thin film of soap or oil will change the direction of the incident ray laterally and cause the prism effect, as the thickness changes the color's change.
LUMINESCENCE or FLUORESCENCE, is stimulated by radiation.
PHOSPHORESCENCE, persisting luminescence after stimulation.
PLEOCHROISM, the change of color when viewed from different directions.
CRYSTAL_CHROMATE [COLOR] ELEMENTS
THERE ARE 92 NATURAL ELEMENTS. EIGHT ELEMENTS MAKE UP 99% OF THE EARTH'S CRUST.
On the ELEMENT PERIODIC TABLE, #22 through #30 are the coloring elements
that give color to crystal compounds. Elements color in harmonies.
Analogous, is side by side around the rim of the color wheel. Centering,
means moving from the high chroma rim to the center's natural dark position.
Complementary colors are opposite colors, 180 degrees apart, triadic colors
form an equilateral triangle, they're 120 degrees between colors. Split
complementary colors are on each side of the opposite, making a "Y".
Aluminum- Easily displaced, makes yellow and sometimes blue.
Arsenic- Yellow, orange red and sometimes greenish.
Cadmium- Green, yellow-green, yellow, orange, red to deep red, a substratum dye. Cadmium is not a solid pigment.

Lead- White, Yellow, Orange, Red, Brown-Purple Mortuum.
Manganese- Light (tint) Pink-Orange [YYMM] in spessartine and rhodochrosite.
Nickel- Yellow-Green [YYYC] in chrysoprase.
Titanium- White pigment, titanium dioxide. Titanium is a centering
element that goes from Yellow to Orange, then Red to Brown and Brown to
Blue in the Rutile crystal. It is an element that can cross over the center
dark, reaching its complementary color Ultramarine Blue. The Real Color
Wheel uses this pattern to darken Yellow instead of using Black as in RGB
color wheel.
The "centering" term means the crystal itself has the ability and
changes from any full spectrum color to a dark colorless color. This color
scale is different in each crystal. The Real Color Wheel follows the crystals
lead.
Vanadium- Green [CCYY] in beryl, Yellow [YYYY], Brown [YYMMCC].
Zinc- Yellow-green in sphalerite.

42,
SPHENE, CaTiSiO5, H5.5, SG-3.5, monoclinic wedged shaped crystals and masses.
TITANIUM, yellow-green or yellow, to brown with neutral dark areas, in a transparent crystal. Centering yellow to neutral dark, through warm brown, is a common trait observed with titanium and iron. This is the way my coloring wheel works with yellow going to Brown as the neutral dark instead of Black. To reach Black, one would need a Transparent Yellow pigment that hasn't been around for a hundred years (1900). The outlawed Indian Yellow Brown Side, from cow urine, from mango leaf feed cows in India. This would mix with a Transparent Ultramarine Blue to a neutral dark. We artists have been deprived. Idiochromatic.

ALUMINUM, yellow-orange, added to the red of iron, idiochromatic.
IRON, red, idiochromatic, transparent.
CHROMIUM, red, transparent, allochromatic. These two elements together make a transparent red and transparent red deeply saturated. This red is so deep and spectrum dark it has to be very thinly sliced to see any color at all. "Deeply saturated" means a transparent to opaque color skipping translucent.

63,
WAVELLITE, Al3[PO4]2[OH,F]3.5H2O, H3.5, SG-2.36, orthorhombic crystal system, acicular, like the needles of Rutile suspended in clear crystal, only these needle crystals form a dense rocklike mass.
ALUMINUM, yellow, brown, blue, centering standard, transparent. Aluminum really does it big this time, each needle starts at the center radiating outward, concentrical ringed bands form around the center, each band ending as a cleavage line, twenty or so bands per complete needle crystal. The band itself can change from clear transparent to opaque white while at the center, the second band range is transparent yellow crystal, then brown, then blue. From brown to blue, the crystal can change into an aggregate and lose it's crystal properties. THIS MINERAL PHOSPHATE SHOWS THE CENTERING OF YELLOW TO BROWN AND BROWN TO BLUE, LIKE MY REAL COLOR WHEEL FOR PIGMENTS.
