In the formation of ceramic objects with a wide range of engineering requires clay must have the required properties, which truly must meet the requirements before use, as this will greatly affect the formation and processing time on the end result.
The success or failure in making ceramic objects will depend on how the above process. So that the clay can be used to form the ceramic objects to be properties dipersyaratan.
Clay must also have the ability to shape, ie the quality of the support form during the formation process takes place that serves as a buffer. Clay that has the ability to form a stand-alone without changing its form during the process of formation takes place and after the formation of completion.
Formed clay will retain its shape when the have plasticity and ability to form a good, in this case it can be said that the clay has a working power.
Working power is influenced by plastistasnya clay, clay with high plasticity, or otherwise low plasticity are less likely to have their power, to be able to use then the clay should be treated specifically in order to have the power to RJA, namely by adding fire clay or grog or reduce ball clay, clay plastistasnya was lower by adding ball clay or bentonite.
That is the nature of the clay body of ceramic objects that have been dried so it is strong enough to be lifted, refined, and arranged in a furnace pemabakaran.
- Clay that has a high plasticity will be higher the dry strength.
- Dry strength is affected: The smoothness of the grain
- The amount of water mixing with other materials forming shaping techniques
