Aromica Genuine
Wet Ground Mica (Natural Glitter)
Basics
of Aromica
Mica
is an exceptionally versatile mineral.
It’s
found as plate-like layers in the soil that are thin,
translucent,
flexible and soft.
Has
natural sheen and luster.
Non-carcinogenic,
non-toxic and totally inert
High
UV stability, low abrasiveness, excellent
lubricity,
good skin adhesion
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?
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.
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.
