Barytes -
Barite is a common mineral and makes very attractive specimens. It often is an accessory mineral to other minerals and can make a nice backdrop to brightly colored crystals. At times bladed or tabular crystals of Barite form a concentric pattern of increasingly larger crystals outward

This product may be used in PAINTS, OIL DRILLING, FILER IN PLASTIC, PAPER, LEATHER, TEXTILE & RUBBER

PHYSICAL CHARACTERISTICS:

• Color is variable but is commonly found colorless or white, also blue, green, yellow and red shades.
• Luster is vitreous.
• Transparency crystals are transparent to translucent.
• Crystal System is orthorhombic; 2/m 2/m 2/m
• Crystal Habits include the bladed crystals that are dominated by two large pinacoid faces top and bottom and small prism faces forming a jutting angle on every side. There are many variations of these faces but the flattened blades and tabular crystals are the most common. If the pinacoid faces become diminished or are absent, the resulting prismatic crystal has a rhombic cross section. Also scaly, lamellar, and even fiberous.
• Cleavage is perfect in one direction, less so in another direction.
• Fracture is conchoidal.
• Hardness is 3 - 3.5
• Specific Gravity is approximately 4.5 (heavy for translucent minerals)
• Streak is white.

GRADE: Potash White Potash Pink
One of the most important materials for medium and high temperature ceramic glazes. It supplies potash, alumina, silica and often some magnesia and calcia to the glaze. Potash feldspars are not usually as pure and white as soda spars. A feldspar is called 'potash' if there is more sodium than potassium. There are no real deposits that have the theoretical 17% K2O, none are even close to this, they have a mix of potassium and sodium.

Glazes high in feldspar (35% or more) are likely to produce crazing problems. 'Flux saturated' glazes with more than 50% feldspar may be unbalanced and lack adequate glass former or alumina

GRADE: Sodium used in CEARMICS
Soda Feldspar is generally a clean white mineral which sources sodium, alumina and silica along with some potassium and calcium. Albite mineral from which soda feldspar is derived is often tends to be white in appearance compared with the pinkish hue of orthoclase mineral from which potash feldspar is ground. It begins melting around 800C.

In many cases soda and potash feldspar are interchangeable in glaze recipes. However, some differences will be apparent. For example, slightly different color responses will be encountered (i.e. cobalt tends toward purple copper toward blue with soda spar). Sometimes colors will be brighter with soda feldspar. In addition, soda spar has a higher coefficient of expansion and melts earlier and has a shorter range before it begins to volatilize.

Because sodium has the highest expansion of all oxides and because soda feldspar is high in this oxide, glazes with a lot of soda spar tend to craze. Thus, if any glaze recipe has more than 30% soda feldspar, it is wise to test carefully to assure the glaze is not in tension.

Formula:
MnO & Mn02

Cubic green crystals that are insoluble in water but soluble in acids

It is a naturally occurring mineral, blackish brown in color and has purity ranging from 60% MnO2 upto 85% MnO2 after processing. It is widely used in the manufacture of dry cell battery, colorings glass and concrete, match box, catalyst and as a factory reagent
