Blue Pottery is one of the most iconic crafts of Jaipur, India. Unlike traditional pottery, it is unique because it is the only pottery in the world that does not use clay. Instead, it uses a sophisticated mix of minerals and glass.
If you are an art enthusiast or a craft blogger, here is everything you need to know about the fascinating process of making Blue Pottery.
What Makes Blue Pottery Unique?
The secret lies in the “dough.” While regular pottery uses soil or clay, Blue Pottery uses a “Fritted Material” made of:
- Quartz Powder: Provides the structure.
- Raw Glass: Gives it a translucent quality.
- Katira Gond (Gum): Acts as a binder.
- Sajji (Sodium Bicarbonate): Helps in the chemical reaction during firing.
- Multani Mitti (Fuller’s Earth): Added in small amounts for plasticity.
The Step-by-Step Making Process
1. Preparing the Dough
The ingredients are ground into a fine powder and mixed with water to create a non-plastic dough. Because this dough lacks the elasticity of clay, it cannot be easily spun on a potter’s wheel.
2. Molding the Shape
Since the dough is fragile, artisans use molds. The dough is rolled into thin sheets (like a tortilla) and pressed into molds. To prevent sticking, the mold is lined with fine ash.
3. Smoothing and Finishing
Once the piece is removed from the mold, it is left to dry in the sun. After drying, the rough edges are smoothed using sandpaper (Regmar). This step is crucial for achieving that signature porcelain-like finish.
4. Painting the Designs
This is where the magic happens. Artisans use brushes made of squirrel hair to paint intricate floral or geometric patterns.
- Cobalt Oxide is used for the iconic Blue color.
- Copper Oxide is used for Green.
- The outlines are usually done in dark blue or brown.
5. Glazing (The Secret Coating)
A special glaze made of powdered glass, borax, and chemicals is applied over the painted piece. At this stage, the colors look dull and earthy, but they transform into vibrant shades once fired.
6. Firing in the Kiln
The pottery is placed in a closed kiln and fired at a controlled temperature of 800°C to 850°C. The firing is a slow process that lasts for several hours, followed by a cooling period of 2-3 days to prevent cracks.
Why Should You Buy Blue Pottery?
- Eco-Friendly: It uses natural minerals and no lead.
- Durable: It does not develop cracks (crazing) easily over time.
- Exquisite Decor: Perfect for vases, coasters, and wall plates.
Note: Because Blue Pottery is fired at low temperatures, it is slightly more brittle than stoneware. It is best used for decorative purposes rather than heavy-duty cooking.
