Pottery takes us to the age of Harrapan and Mohanjodaro - the first developed Civilizations of India.The art of Blue Pottery was first brought to India by the Persians.
In 1866 AD Sawai Ram Singh, the Maharajah of Jaipur invited Dr. Hunter from the Madras School of Art to advice on the art manufactures in jaipur. Hunter suggested that nearby Jaipur theirs deposits of gypsum. Even in Old capital amber fort were decorated by glazed tiles. Some of the families still work in this art. Later with the help of Madras school King Ram Singh again revive Blue pottery in Jaipur.
Now Jaipur is the only place in the world where this art is still practiced.
The ingredients and the process was quite different from a normal potters clay. No clay is used: the 'dough' for the pottery is prepared by mixing quartz stone powder, powdered glass, Multani Mitti (Fuller's Earth), borax, gum and water. Another source cites Gond powder (a gum), and saaji (soda bicarbonate) as ingredients.
The felspar was obtained from the hills near Jaipur and the marble came from Makrana on the Jodhpur border. Both the cobalt and copper oxides were found in Jaipur state itself. The clay ware was made from a white clay (possibly a china clay) from the Bochara Hills, close to Jaipur. Use of Fullers Earth - Multani Mitti as the base of any pottery. However the Indian Concept is a mix of Fullers Earth, Chinese Glazing Technology with Indian Designs. The main and only color used in Blue Pottery is the Sky Blue Color with the base as Pure.
Making Processes have two major part –
I. Making of pot
II. Painting the motifs and coloring the pot and bake in heat chamber than dies get original blue color.
Before blue-painting on the plane surface of tiles the mixture of 50% and 15% gum is coated. On drying,
it appears white. The outline of the design is drawn with a pen or brush by using 75% cobalt and 25%
water mixture. Border is designed in the same way.
After this the design or picture is colored by using the mixture of 75% copper and 25% water. A panel can be made by joining tiles for big designs. For this purpose, the design is first carved on paper and then printed on tiles with the help of powdered coal on the completion of the design. 85% glass powder 15% gum glaze mixture is spread on tiles still the design is printed. In the last step, the glazed tiles or pots are heated very carefully and skillfully in a special kiln which runs at a temperature of 1200oC. on melting, the graze is removed and design appears into its true colors. After mellowing in kiln, cobalt appears blue and copper appears turquoise blue in color.
