The brassware photos and hollow brass objects are cast making use of the process of lost wax or cire perdue. 1st the Dokra artist has to envisage the image he wishes to develop in his head. For that he has to meditate hard. At the time he is positive and confident that he has the total picture in his brain, he will try out to give concrete condition to the picture he has in his intellect in wax.
That is why it is stated that the essence of Dokra craft is to first give shape to the preferred model or item in a soft mattress of bees wax individually.
This wax determine is encased in a hardened main of clay that is fairly near to the duplicate of the object that is about to be cast. Generally ample amount of molten material or molten steel is poured into the clay encasing by way of a gap at the prime.
These layers of refractory soft product will be poured all about the model in wax and then the full matter will be remaining to dry. Either the mildew will be heated and dried in the furnace or it will be still left in the sunshine to dry. Possibly approaches, the mildew will get hardened as it dries up.
When the mould is staying heated the wax in the wax design is lost or it vaporizes and melts in warmth. That is why it is named the dropped wax method. All through the course of action of heating up, the wax that will get burnt out or misplaced was put concerning the mildew and the core.
When the wax vanishes, the molten steel flows down the wax channels and normally takes the location of the shed wax. This molten metallic will get hardened while staying among the mold’s internal floor and the core.
The wax model’s negative impact is captured in all its particulars in the mold’s interior surface. The hollow interior of the figurine is created by the hollow main. When the entire thing is fired, the mould and the hard main change tender and spongy and the Dokra artist can then easily take out them.
The finished Dokra/Dhokra item is given a final spherical of fantastic polishing, expressive functions are added and it’s smoothed down to increase the attractiveness and luster.
