China Clay is a hydrated Aluminium silicate, part of the group of industrial minerals, with the chemical composition Al₂Si₂O₅(OH)₄. It is a layered silicate mineral, with one tetrahedral sheet linked through oxygen atoms to one octahedral sheet of alumina octahedra. Rocks that are rich in Kaolinite are known as kaolin or china clay. Kaolinite has a low shrinkswell capacity and it is a soft, earthy, usually white mineral, produced by the chemical weathering of aluminium silicate minerals like feldspar. In many parts of the world, it is colored pink-orange-red by iron oxide, giving it a distinct rust hue. Lighter concentrations yield white, yellow or light orange colors. Commercial grades of kaolin are supplied and transported as dry powder, semi-dry noodle or as liquid slurry. The largest use is in the production of paper, including ensuring the gloss on some grades of paper. It is also used in paint, rubber, detergents & textile industries.

Quartz crystals are comprised of silicon dioxide and they form in a wide variety of different colors and types. Many are transparent or translucent and they are configured in many different ways, and in a range of attractive colors.

Many of the stones made from quartz have powerful healing qualities. Their attributes are quite diverse and many have potent vibrations. Quartz has many excellent qualities including being able to be programmed, and this makes it a powerful stone to use to assist you to manifest those things you desire.

Quartz is used by industry because of its piezoelectric qualities and its amplification properties. It is this specific quality that makes these stones very powerful for metaphysical purposes, and creates strong healing attributes within the stones.

Pure quartz, traditionally called rock crystal or clear quartz, is colorless and transparent or translucent, and has often been used for hardstone carvings, such as the Lothair Crystal. Common colored varieties include citrine, rose quartz, amethyst, smoky quartz, milky quartz, and others.

• Amethyest : Amethyst is a popular form of quartz that ranges from a bright to dark or dull purple color.  Sometimes amethyst and citrine are found growing in the same crystal. It is then referred to as ametrine. An amethyst is formed when there is iron in the area where it was formed.
• Citrine : Citrine is a variety of quartz whose color ranges from a pale yellow to brown due to ferric impurities. Natural citrines are rare; most commercial citrines are heat-treated amethysts or smoky quartzes. However, a heat-treated amethyst will have small lines in the crystal, as opposed to a natural citrine's cloudy or smokey appearance. It is nearly impossible to differentiate between cut citrine and yellow topaz visually, but they differ in hardness.
• Milky Quartz : Milk quartz or milky quartz is the most common variety of crystalline quartz. The white color is caused by minute fluid inclusions of gas, liquid, or both, trapped during crystal formation, [citation needed] making it of little value for optical and quality gemstone applications.
• Smoky Quartz : Smoky quartz is a gray, translucent version of quartz. It ranges in clarity from almost complete transparency to a brownish-gray crystal that is almost opaque. Some can also be black.
• Rose Quartz : Rose quartz is a type of quartz which exhibits a pale pink to rose red hue. The color is usually considered as due to trace amounts of titanium, iron, or manganese, in the massive material. Some rose quartz contains microscopic rutile needles which produces an asterism in transmitted light. Additionally, there is a rare type of pink quartz (also frequently called crystalline rose quartz) with color that is thought to be caused by trace amounts of phosphate or aluminium. The color in crystals is apparently photosensitive and subject to fading
• 6 Sided Pencil Quartz/clear Quartz : These are 6-sided Clear Quartz Pencil Crystals from India that would be great to use in healing sessions and in Grid sets. Clear Quartz can be "programmed" with your intent and you can use it to support any intention or goal you may have throughout the day.Extremely popular metaphysically, Clear Quartz is known as the "Master Healer" of the mineral kingdom, with its very high vibration, and is the most versatile healing stone among all crystals. Quartz is said to be the most powerful healing stone of the mineral kingdom, able to work on any condition. Clear Quartz is also known as the stone of power and amplifies any energy or intention. Clear Quartz is believed to protect against negativity, attune to your higher self, and relieve pain. Quartz crystals are very programmable and have a tendency to hold a program much longer than other minerals.

• Green Quartz Or Vermarine :
  • Green Quartz is type of quartzthat containsinclusion of bothchromium or chloriteinterspersed within the quartz's crystalline matrix to give a solid green appearance.Green Quartz has a healing effect when worn or carried.  Use Green Quartz to help transmute negative energies into positive ones. Green Quartz is also known to attract prosperity and success and to stimulate one’s creativity. Carrying Green Quartz will help to activate the Heart Chakra, and impart a sense of wholeness to the owner.
  • By opening, activating and/or stabilizing the Heart Chakra, Green Quartz can help one to feel empathy and universal love for others, and as such, is a great stone for people who are overly selfish or controlling.  Green Quartz has a pleasant vibe and can have a positive effect on the environment if placed strategically in a room. Energy healing can be enhanced with Green Quartz by laying this stone on the Heart Chakra.

Feldspar is by far the most abundant group of minerals in the earths crust, forming about 60% of terrestrial rocks. Most deposits offer sodium feldspar as well as potassium feldspar and mixed feldspars. Chemically, the feldspars are silicates of aluminium, containing sodium, potassium, iron, calcium, or barium or combinations of these elements. Most of the products we use on a daily basis are made with feldspar: glass for drinking, glass for protection, fiberglass for insulation, the floor tiles and shower basins in our bathrooms, and the tableware

Feldspar properties:Basically, the two properties which make feldspars useful for downstream industries are their alkali and alumina content. Feldspars play an important role as fluxing agents in ceramics and glass applications, and also are used as functional fillers in the paint, plastic, rubber and adhesive industries. The glass &ceramic industriesare the major consumers offeldspar. This makes it a veryessential mineral in our day-to-day life.

Industrial Applications:

• Ceramic Industry : Ceramics Industry Feldspar is used as fluxing agent in all kinds of ceramics & glazes. In the manufacture of ceramics, feldspar is the second most important ingredient after clay. Since feldspar does not have a strict melting point it melts gradually over a range of temperatures. This greatly facilitates the melting of quartz and clays and, through appropriate mixing, allows to modulate this important step of ceramic making. Feldspars are used as fluxing agents, to form a glassy phase at low temperatures, and as a source of alkalies and alumina in glazes. They improve the strength, toughness, and durability of the ceramic body and cement the crystalline phase of other ingredients, softening, melting and wetting other batch constituents. In the flooring sector, feldspar is the main constituent in the body composition.

• Glass Industry :Both Sodium and Potassium feldspar is used in glass industry. Feldspar is an important ingredient in the manufacture of glass and an important raw material as well, because it acts as a fluxing agent, reducing the melting temperature of quartz and helping to control the viscosity of glass. The alkali content in feldspar acts as flux, lowering the glass batch melting temperature and thus reducing production costs. But feldspars are primarily added to glass batches for their alumina content, which improve hardness, durability, and resistance to chemical corrosion.

• Paints :Feldspar is used as a filler in paints & coatings industry. Feldspars are also used as fillers and extenders in applications such as paints, plastics and rubber. Beneficial properties of feldspars include good dispersability, chemical inertness, stable pH, high resistance to abrasion, low viscosity at high filler loading, interesting refractive index and resistance to frosting. The products used in such applications are generally fine-milled grades.
• Enamel frits and glazes:Feldspar enters in the enamel composition, assuring the absence of defects and the neatness of the end product: enamel frits, ceramic glazes, ceramic tile glazes, sanitaryware, tableware, electrical porcelain and giftware to name just a few.
• Other uses:in plastics & rubber industries as a filler, in mild abrasives, urethane, welding electrodes (production of steel), latex foam, as a welding rod coating , road aggregate

Quartz is a chemical compound consisting of one part silicon and two parts oxygen. It is silicon dioxide (SiO₂). It is the most abundant mineral found at Earth's surface and its unique properties make it one of the most useful natural substances. Quartz is the second most common mineral in the Earth's continental crust. It is made up of a lattice of silica (SiO₂) tetrahedra. Quartz goes by an array of different names. The most important distinction between types of quartz is that of macrocrystalline (individual crystals visible to the unaided eye) and the microcrystalline or cryptocrystalline varieties (aggregates of crystals visible only under high magnification). Its usefulness can be linked to its physical and chemical properties. It has a hardness of 7 on the Mohs' Scale which makes it very durable. It is chemically inert in contact with most substances. It has electrical properties and heat resistance that make it valuable in electronic products. Its luster, color and diaphaneity make it useful as a gemstone and also in the making of glass. Industrial

Applications :

• Glass Making : High purity silica sand (Quartz sand)is used in the glassmaking industry. Quartz sand is used in the production of container glass, flat plate glass, specialty glass and fiberglass.

• Abrasive Material : Quartz is an excellent abrasive material. Quartz sands and finely ground silica sand are used for sand blasting, scouring cleansers, grinding media, and grit for sanding and sawing.

• Foundry Sand : Quartz is very resistant to both chemicals and heat. With a melting temperature higher than most metals it can be used for the molds and cores of common foundry work. Refractory brick are often made of quartz sand because of its high heat resistance. Quartz sand is also used as a flux in the smelting of metals.

• Petroleum Industry : Quartz sand has a high resistance to being crushed. In the petroleum industry sand slurries are forced down oil and gas wells under very high pressures in a process known as hydraulic fracturing. This high pressure fractures the reservoir rocks and the sandy slurry injects into the fractures. The durable sand grains hold the fractures open after the pressure is released. These open fractures facilitate the flow of natural gas into the well bore.

• Many Other Quartz Uses : Quartz sand is used as a filler in the manufacture of rubber, paint and putty. Screened and washed, carefully sized quartz grains are used as filter media and roofing granules. Quartz sands are used for traction in the railroad and mining industries. These sands are also used in recreation on golf courses, volleyball courts, baseball fields, children's sand boxes and beaches.

Garnet is the name used for a large group of rock-forming minerals. These minerals share a common crystal structure and a generalized chemical composition of X3Y2(SiO4)3. In that composition, "X" can be Ca, Mg, Fe2+ or Mn2+, and "Y" can be Al, Fe3+, Mn3+, V3+ or Cr3+.
These minerals are found throughout the world in metamorphic, igneous, and sedimentary rocks. Most garnet found near Earth's surface forms when a sedimentary rock with a high aluminum content, such as shale, is subjected to heat and pressure intense enough to produce schist or gneiss. Garnet is also found in the rocks of contact metamorphism, subsurface magma chambers, lava flows, deep-source volcanic eruptions, and the soils and sediments formed when garnet-bearing rocks are weathered and eroded.
Most people associate the word "garnet" with a red gemstone; however, they are often surprised to learn that garnet occurs in many other colors and has many other uses. In the United States, the major industrial uses of garnet in 2012 were waterjet cutting (35%), abrasive blasting media (30%), water filtration granules (20%), and abrasive powders (10%).

Application Of Garnet :They are used in waterjet cutting, "sand" blasting, sandpaper, water filtration, and a number of other uses. Almandine is the hardest garnet and also the most abundant. It is the garnet of choice for most abrasive applications.

• Garnet Sand For Sand Blasting : In the process of surface preparation, Super Garnet is blasted on to the surface of the steel with the use of high pressure compressed air.
