Genuine Wet Ground Mica (Natural Glitter)

 

 

Basics of Aromica

 

 

v           Mica is an exceptionally versatile mineral.

 

v           It’s found as plate-like layers in the soil that are thin,                

 

v           translucent, flexible and soft.

 

v           Has natural sheen and luster.

 

v           Non-carcinogenic, non-toxic and totally inert

 

v           High UV stability, low abrasiveness, excellent  

 

v           lubricity, good skin adhesion

 

v           Excellent resistance to heat, weather, and chemicals

 

 

Grinding of Mica

 

 

Mica is one of the most difficult minerals to grind. Even the thinnest flakes are tough, elastic and slippery and resist abrasion and consequently grinding it is a slow, costly and difficult operation. It is all the more difficult operation to grind it to fine mesh without any deterioration of its natural brilliance, gloss and color.

 

 

Why Wet Ground Mica?

 

 

v         If mica is grounded like any other minerals, that is in any conventional Ball Mill or Hammer Mill, it will lose it’s luster. This is because in doing so, the surface of the plate-like layers of mica gets scratches.

 

v           To preserve the Plate late (i.e. lamellar) structure of the mica, one has to grind it in wet condition, that too with soft grinding medium.

 

 

Unique Grinding Technique

 

 

Aromax Corporation has found out a unique way to ground the mica in such a way that this integrity of the particle surface is preserved. Its surface is kept free from scratches and defects so that the lamellar structure is not disturbed. The result is a shimmering, sparkling, luminescent powder.
