Pyramidal Shape: It is like pagoda style where all point faces meet at a fixed point with either triangular or quadrilateral base.
Cylindrical Shape: A solid with two parallel circular bases like a roll. If you unwrap the middle section and lay it flat, it becomes a rectangle.
Conical Shape: It is like a funnel where the base is circular and a curved side that ends at one point .
Spherical Shape: It is like a ball where all points are equidistant.
Every object has its shape. For example, an apple has a spherical shape, a banana is a curved cylinder, and the book has a rectangular prismatic shape. There are certain steps to create a shape of an object with clay.
Soil Preparation: The first step is to find an appropriate soil. Clay soil can be found in ceramic suppliers. You can find quality soil in Gadawa of Dang district.
Wedging:Secondly, mix the clay with water. Mix and firm pressure homogenously till it becomes flexible and removes air bubble which might damage work.

Forming: Clay is shaped or molded in the various forms.
Drying: Once the clay is formed, it is dried in shade for a few days. They will become stiffer and lose flexibility.
Greenware: When the piece of poetry product has dried completely, it is referred to as a piece of greenware. It means the piece is awaiting the first firing until enough pieces have accumulated to fill a kiln .
Firing: After the products are dried to greenware and enough pieces have accumulated to fill a kiln, then they can be processed for firing . On the first day, the kiln is lit at a lower setting to dry the ware and left overnight to slowly warm .Firing too fast during this early stage of the firing can cause damage to the work . On day two, the kiln is gradually turned to a higher temperature up to 900 – 1000 degree Celsius. The kiln is then turned off and cooled down slowly. On day three, the kiln is opened and the products are taken out.
Glazing: The glazing substance could be a mixture of ground glass, clays, a coloring material and water. They are applied to the pot.
Glaze Firing: Again, the firing process is a three-day affair. Glaze firing temperature is raised up to around 1200 degrees Celsius for one day and a half and they are allowed to cool down. On day three, they are unloaded from the kiln and stored in the room.
It is difficult to follow all the given steps. There is another safe method that you can try at your home or at school.
