Myanma Traditional Handiwork of Casting

The handiwork of making items cast or wrought
from bronze, copper or brass is one of the ten traditional
arts and crafts. Casting bronze Buddha images, bronze bells
and triangular brass gongs include in these arts and crafts.
Since the time of ancient Myanmar monarchs to the present
day, the art of casting items was carried out as household
industry at bronze casting part of Tanpawadi Ward in
Chanmyathazi Township, Mandalay. Painting and crafting are
added in the handiwork of casting.
In preparations for casting of bronze Buddha images,
mixing of clay, husks and water comes first. The rough
models of Buddha images are made of the mixed clay by
craftsmanship. The clay model is only a rough one. The
next step is to paste thin wax plates on the whole clay
model. Joints on it are then polished. The model is then
touched with the arts of crafting in detail. It is done
so as the smelted bronze will take the place of the wax.
The craftsmanship of the model depends on waxing of the
clay model and polishing it in detail. After various
processes of finishing touches, the rough models are
covered with wax. They are again pasted with clay and
taken down for pouring the smelted bronze liquid into
the models, which are baked in an oven to melt the wax
in them and to let it flow out. The models are then
tightly bound with steel planking to keep them together.
The rough models are then baked in a brick oven and
given heat to an extent. Later they are taken out of the
oven and placed upside down in a pit in the ground for
the smelted bronze liquid to be easily poured into the
models. Bronze and zinc are mixed and given heat to
smelt it. One kilo of bronze is mixed with 70 % of zinc
to acquire golden colour. When the mixed metals are
smelted, it is poured into the models in the pits
through ready-made holes in them. Manpower is vital in
pouring the smelted bronze into the model and it is also
harmful. The smelted bronze is systematically poured
into the model by experience of the workers. If their
guess is incorrect, thinness and thickness of the bronze
layer inside the model will not be equal. Then take the
models out of the pits and keep for two days to cool
down the heat. The clay pasted on the models is hammered
out to separate it from the models. Then the bronze
welding is given according to requirements. A process of
finishing touches is carried out on the models, which
are then polished with Ingyin stone powder (petrified
wood) so as to shine them.
Those who cast the bronze are skilful to decide thinness
and thickness of the smelted bronze liquid and weight of
the metal by guessing. We can see today various kinds of
significantly cast bronze handiworks in shops at pagoda
archways. The handiwork of bronze casting is a
traditional heritage, which had been presented
generation-to-generation.
