Production steps:
The enameller use different kinds of
metal oxide for enamel paint since, the chemical actions help to
firm the paint on metal vessels. The best metals are gold, silver
and copper. But copper is better than other, since it is cheap,
available and easy to shaping. The enamel paints are divided to
two
groups: 1. non material paints: These are used rarely on gold or
silver sheets, since; they are glass from and cover the metal
surface in form of gem. This art is rarely common and is depend on
customer's order. 2. Material paints: These paints can cover the
whole surface of metal and we can see the paint not the real
colour of metal. This method is common between all masters of
enameling in Iran. So this kind of art is made by metal oxide and
material paints on copper sheet in Iran.

The copper is a first material of
enameling and is prepared from copper mines of Kerman city in
form of 60x200 cm sheets with 0.8 to 1.5 mm thickness. |
|
 |
|
|
|
 |
|
Then this sheets is
cut to special sizes and copper smiths give shape to them by
bending and hammering in form of different kinds of vessels. Then
carvers emboss the surface of vessels by hammer and chisel. This
embossed surface is washed by sulphuric acid and so, the copper is
become clean and shiny. |

|
After, the white paint is sprayed on
surface in three times and after each time put the vessels on
furnace with 800'C temperature for two minutes. |
|
 |
|
 |
|
In this stage the vessels are
completely while colour and ready for enameling. |
|
|
|
 |
|
But we must notify that the
temperature and time for baking is depend on the size and
dimension of vessels. All enameller works depend on their
special interest and cultural specification. In Iran, there are 3 methods for
enameling: 1. Bird and flower design 2.gilding
3.Golkhatai 4.Chang&Eslimi. |
|
 |
|
|
|
|
After painting, the enameling vessel
is baked on furnace again but with 700'C temperature for 1-1.5
minutes. Also, is depends to size and dimension of the vessel.
|
|
 |
 |
|
At final these vessels are ready and
are anti-friction, anti-heat and can wash them without any
trouble and changing in colour or form. |
