To build the enamel products, infrastructure is provided in two ways:
In the bending method, place the mold on the plate, pot, or any other object between the mold and the clamping device. When the sheet with the round bar metal bar rotates, it bends the weight with the pressure on the mod.
In hammer work, without using the mold, with taking advantage of metal hammering tolls, the product would be made in the desired shape, and after each hammering, the metal piece would be placed on the fire to reach the proper shape.
The second step is to learn how to remove various contaminants from the infrastructure level. First of all, the surface of the metal must be clean enough to adhere to the enamel glaze. Even the artist's fingerprint will remain on the infrastructure and it will prevent gluing the enamel glaze to the copper.
process of meenakari
Different methods are used to clean the enamel surface:
1. Put the product in a container that is proportional to its dimensions, and the full it with the combination of salt and vinegar and then brush it with a wire.
2. Use of Sulfur Injection: The product is placed in a hot solution of sulfuric acid and then clean it with a wire brush. Then it will wash with water to remove the acid completely.
3. Use of metal fibers, soap, polisher, and salt: At the end of the job, the cleaned object is washed with clean water and dried with sawdust. Then, before glazing with air compressors the surface of products will clean from the dust.
preparing the glaze is the third step of the Mina Kari, the enamel powder is insoluble and has a large volume and can not be used alone. For this purpose, they use a solution like glazing seeds to dilute enamel particles in water.
Glazing in Isfahan Minakari is the fourth step of the Mina enameling that takes place in two ways:
- Pistol spray: Powdered gypsum is sprayed on the infrastructure in a chamber called spray chamber. This chamber is equipped with a ventilated system to protect the spray from poisonous suspended particles in the air that is toxic. Some glazes are wasted in this way.
- Fluid or manual method: In this method, the glaze is placed on the desired product to cover its entire surface. In the manual method, the glaze is prevented and its health and economics are preferable to the previous method.
After glazing, the enameled product should be placed in a dust and dust environment near the furnace or in the home, and then thawed again into the compressed air before placing the product in the furnace.
Another step in the process of meenakari is cooking the glaze. After completely drying the glaze and clearing all the dust from the product, the glazing step would start. When cooking, the heating of the furnace is 900 degrees centigrade and the baking process usually takes 2 to 3 minutes, and when the desired red is obtained, the object would remove from the furnace and place next to the furnace to cool.
Older traders get enough experience and evidence and do not use the thermometer. In this case, the glaze becomes buff yellow and gradually becomes white when the temperature drops.
The sixth step is the preparation of the paint. The old fireproof paints used to paint on the enamel background and formed from metal oxide powders, but nowadays chemical ready-to-use powder paints have been using.
To prepare these colors, Arabic gum must be mixed with glycerin in water, and after preparing the powder for the color of the glass, they prepare the color and use it. Arabic gum mixes with glycerine are using as a color solvent.
The seventh stage is the transfer of the project to the glaze, for which the artist makes his design, which usually brings flowers, chickens, hunting, make-up, and Persian craftsmanship and Slavic designs to the paper, and then carves the work of a crochet or a needle. To give Eventually, with ash or soot, it runs on an enamel piece.
The eighth stage is the drawing on the white enamel that begins with filling, at first filling of the main lines of the design takes place, and then the coloring of the other sections is done. You can also first paint the design and then fill it.
The point that is important is that there is no white color in the Mina colors, and if the use of white is necessary, the artist will use the white enamel with his skill or after painting with a Sharpen tip of the special toll remove the Mina color from the background until white glaze appears. If the design has a golden color, at this stage they would add water.
In the painting step, if you use oils such as lavender and glycerin, you should place the object on a flame or electric stove to expel it from the smoke and remove it, because if the oil does not disappear, on the enamel surface would form like Smallpox or some pores may appear on it.
The ninth stage is to cook the painting, after painting on the glaze, the piece should again be placed in a furnace under a temperature of between 600 to 750 ° C. If gold is used for coloring, the maximum temperature should be 450 ° C because gold will disappear at higher temperatures.
The point is that the heating of the enamel, especially in the painting process, should be done with great care; if the heating of the furnace or the heating time exceeds the limit, it causes the paint to flow or penetrates into the initial enamel.
Also, if the heat and temperature are lower than the limit, the color is not cooked properly and after baking it easily clears from the glaze or becomes cloudy. After finishing the cooking, they will cover the enamel with a transparent glaze and then they will cook it again.
The glaze can not properly cover the base of the enamel objects and the edge of the dishes and the plate and the pot, and it gives it a bad appearance. In order to eliminate this defect, they use brass and silver straps.
