Quartz is one of the most commonly available minerals in the earth. It is found as a main part in Pegmatites and hydrothermal veins and occurred in many different rocks as Igneous, Metamorphic and Sedimentary.
Uses of Quartz : Quartz is used in making various types of Glass and Ceramics. And it is main raw material for Glass and Ceramic Industries, It is used for construction work and foundry molds. Quartz is also used as a filter for some liquids and in making sandpapers, scouring powders and whetstones.

Fireclay is generally of sedimentary origin. Strictly speaking, fireclay is of sedimentary origin and mainly found in the coal measures, as bedded deposits.
A group of refractory clays which can stand temperatures above Pyrometric Cone Equivalent (PCE) 19 are called fireclay. The clay which fuses below PCE 19 is not included under refractory. Fireclay is essentially of kaolinite group and has a composition similar to that of china-clay. In nature it is usually found to contain 24-32 per cent Al2O3, 50-60% SiO2 and LOI between 9 to 12%. Impurities like oxides of calcium, iron, titanium and magnesium and alkalies are invariably present, making it white, grey and black in colour.
Like other clays, this clay is highly malleable in raw form. It can be molded, extruded, shaped by hand, and stamped. Various additives can be mixed in to make it more coarse, and it can be ground to be smoother. Slip and scraps for fire clay manufacturing can also be recycled, as long as they are not fired, and worked into new batches of clay for use. Fire clay also shrinks after it has been molded .
Refractoriness and plasticity are the two main properties in fireclay for its suitability in the

| NATURAL GRAPHITE : Graphite most commonly occurs in metamorphic rocks, such as crystalline limestones, schists and gneisses. It may occur as large crystalline plates. It has probably been derived from carbon material of organic origin which has been converted into graphite during the metamorphism of the rock. Coal beds, under influence or strong metamorphic action, such as the intrusion into them of an igneous rock, have in a greater or less degree been converted into graphitic.

Vermiculite is a mica-like mineral which exfoliates (expands or "pops" upon rapid heating) to produce an inert, low-density material with significant thermal qualities
- it does not burn and provides excellent heat resistance. Vermiculite has been used in various industries. It is used in the construction, agricultural, horticultural, and industrial markets.
Vermiculite is the mineralogical name given to hydrated laminar magnesium-aluminum-iron silicate which resembles mica in appearance. When subjected to heat vermiculite has the unusual property of exfoliating or expanding into worm-like pieces .This characteristic of exfoliation, the basis for commercial use of the mineral, is the result of the mechanical separation of the layers by the rapid conversion of contained water to steam.
The increase in bulk volume of commercial grades is 8 to 12 times, but individual
flakes may exfoliate as many as 15 times. There is a color change during expansion that is dependent upon the composition of the vermiculite and furnace temperature. .
