African Stone Transformation Process:
There are several common
features of sculptures & art pieces from Zimbabwe,
Cameroon,
& South Africa. The first
is the material used; Artists use locally found
stone. The most common being serpentine stone. Other
stones include verdite, steatite, and opal stone.
When sculpting, the artist and the stone develope
a relationship with one another. The artist follows
the form of the stone, no sketches are drawn before
carving. Quintessentially, the stone dictates to
the artist what subject emerges from within its
core. The tools that are used, are the hammer, chisel,
file, water, and sandpaperr. Once the artist has
completed sculpting the stone they place it in a
fire where the stone is heated. Next they apply
a dark oil which melts and absorbs into the stone,
bringing out the stone's rich deep luster &
colorful veinage. Lastly they wipe the piece clean
and whoola, ready to show at the local market.
Types of Stone:
Shona Stone
In Africa, soapstone may also be referred to as
shona stone because the shona tribe make their art
carvings from it, being native to Zimbabwe. The
stones used are Soapstone, "liquid" black
& green serpentine with fleched and veined yellows,
greens, goldens and greys, spots & patches of
with earthy brown and red colored veinage, and opal-ites
giving a huge scope of textures and colours to complement
every form or image represented.
Verdite
Known as "Africa's green gold", is highly sought
after by artists. Only the more experienced sculptor
will dare sculpt from this hard stone. Verdite rates
between a 7.0-9.0 on the Mohs hardness scale. Verdite
has color unique in that it boasts an Emerald looking
quality with beautiful brown and green striations.Unfortunately,
verdite is fast becoming rare and is difficult to
find. Carvings from this stone will become increasingly
more valuable.
Serpentine
Black iron serpentine is one of the hardest and
darkest stones found in Zimbabwe. Black iron serpentine
gets its name because of the deposits of iron found
in it. The stone is capable of the most amazing
finish that shines a black lustre resembling the
black opal. Rated at 4.0-5.0 on Mohs hardness scale,
serpentine's remarkable hardness guarantees its
durability and because of its fine finish, is highly
sought after.
Opal
Opal stone is unique in that it has fewer color
variations than serpentine. It does however, rate
higher on the Mohs hardness scale with a rating
between 5.0-5.5. This is comparable with black iron
serpentine. Southern African opal is famous for
it's milky light colored greens and smooth texture.
Soapstone or Steatite
Soapstone is also known as Steatite, sometimes called
talc; A soft metamorphic rock mined for centuries
in africa. It can be found along faults in magnesium-rich
rocks. And is less frequently found as a result
of thermal metamorphism of dolomitic limestone.
It's distinguishing features are extreme softness,
soapy feel, and greenish white colour. Although
somewhat soft, soapstone is a very dense stone.
Many people wrongly associate softness with porosity.
Soapstone is actually denser than marble, slate,
limestone, and even granite. Because soapstone is
so dense, it will not stain. For example, if anything
was spilled on the stone, it would stay on the surface
of the stone, and not penetrate the surface. The
only maintenace for soapstone, is the application
of mineral oil, which will enhance the natural darkening
process the stone goes through.
Caring for Wood Carved Products:
All fine wood products need moisture and in
the dry climate of a home or business will become
dried out and may crack. To prevent or reduce the
chance of damage it is best to polish wood items
about once every 4-6 weeks with a high quality wood
polish. Spray on polishes are not as effective because
they are used mostly for removing dust from finished
wood and do not add adequate moisture. Africans
will often use black shoe polish, which not only
adds moisture but also sheen to woods such as ebony
or mahogany. Simply rub the polish in using a clean
cloth or shoe brush, then buff with a clean soft
cloth.
Types
of Wood:
Ironwood
Has a dark red or deep reddish brown color. The
timber is rated very durable. Ironwood is a common
name for a wide variety of african trees or shrubs
that have exceptionally hard or dense wood. Although
the name is applied generally to trees of three
unrelated genera, scores of other trees are also
called ironwood in local usage. Because it is so
dense it will not float in water, carving anything
from it can be extremely difficult. To properly
care for your ironwood carving, apply a light coat
of brown or neutral paste type shoe wax, then polish
with a soft cloth.
Ebony
Wood
A black hardwood, famous for it's lustrous beauty.
It is a delicacy in the world of the African wood
sculptor. Skilled ebony sculptors tend to migrate
to the few regions of Africa where ebony wood is
grown. A highly dense wood with a coarse texture
and a dark interlocking grain, ebony wood normally
is brown on the outside of the tree; and black on
the inside. The carvings often come as a beautiful
mixture of black and brown; but it is mostly the
pure dark black wood that is the most well known
grain.
African
Walnut
From the walnut tree, walnut wood is a hard, dark
brown wood with bronze, yellow-brown dark irregular
lines. Like all wood art pieces, it is hand-carved,
sanded, polished, and most importantly, treated
with oils to darken and add richness to the color
of the wood. It has an lot of cross grain and is
moderately heavy, very strong for its weight, &
exceptionally stable.
Mahogany
Wood
Straight, tight, interlocking grain with a rough
surface with reddish-brown to light brown color
wood.
Olivewood or Olea Europaea
Has a straight grain with a fine texture & red
color varing slightly with each piece. Olivewood
grows almost exclusively along the Mediterranean
coast. Olivewood is used for small turnings, carvings,
and inlay work.
Lead
Wood
This tree is found anywhere from Tanzania to Kwazulu-Natal,
in Southern Africa. The heartwood is very hard and
heavy. Giraffe, elephant, kudu, grey duiker and
impala feed on them. Lead wood is a protected species
of tree in Southern Africa.
Types of Metal:
Antique Steel Sickle
Solid Bronze Casting
Brass Horn Stand
Copper & Tin Sheets
Other Materials:
Cow horn
The horn of cattle consists of three distinct parts:
a short inner bony frame, a membrane and the outer
horn. It is the outer horn that is used. This outer
portion is made up of little "tubules" or "granules"
of keratohyalin imbedded in a solid plastic-like
matrix. These tubules are the reason that horn appears
to be made of very fine hairs, running lengthwise.
Cow horn is thicker in nature, while Steer horn
is thinner. While cattle horn can be nearly any
color, it is generally a light creamy color, sometimes
streaked with white, brown or black patches. Buffalo
horn is nearly always entirely black.
Woven fabric 1

Using coarse yarns & threads tribal artist make
masks with every detail from the beard to the eyes
of a mask woven in consistent patterns to arrive
at complete art piece. |
