Of all clays, porcelain clays are the toughest and hardest. Because of their transparency and purity, they are frequently utilized for delicate items like fine porcelain. They are also used to create items like teapots and vases that need a high level of precision.
Earthenware clays are in between soft and stoneware clays in terms of strength and hardness. They are frequently employed to create items that need to be more resilient than soft clay objects but are not intended for heavy use.
Terra Cotta Clays
Terra cotta clays are an earthenware clay variety distinguished by their reddish-brown hue. They are frequently employed in the production of outdoor décor items like garden pottery.
The kind of clay used for slabs relies on the desired result and intended usage of the finished product because each kind of clay has its own distinct qualities. The ultimate appearance and feel of the sculpture, as well as its strength and durability, will depend on the choice of clay, whether it is soft or hard.
What Are The Different Firing Techniques That Can Be Used For Slabs?
The ceramics process involves firing, which turns the clay into a firm, long-lasting material. Slabs can be fired using a variety of methods, each of which has advantages and disadvantages that are specific to that method.
This method of firing clay entails heating it to a temperature of between 1000°C and 1200°C. Making decorative items and garden pottery frequently involves using this form of fire, which works best for earthenware and terra cotta clays.
Electric Kiln Firing
Electric kiln firing is the process of heating clay in an electric kiln. This method is adaptable because it enables the potter to regulate the temperature and environment inside the kiln to produce various effects on the finished product.
Gas-fired kilns heat the kiln with either natural gas or propane. Because it enables higher fire temperatures and better environment control inside the kiln, this method of firing is perfect for clays used to make stoneware and porcelain.
Wood-fired kilns heat the kiln by burning wood as a fuel source. Each item is distinctive thanks to the distinctive and erratic characteristics this process produces on the finished product, such smoke markings and ash deposits.
The clay is taken out of the kiln while it is still hot and placed in a reduction chamber with materials like sawdust or leaves. Raku firing is a low-temperature firing technique. The finished product is altered dramatically and uniquely by the reduction process, which also produces interesting colors and crackle patterns.
The ultimate appearance and feel of the object will depend on the firing technique used, as each one has specific advantages and disadvantages. Depending on their own preferences, the clay they are using, and the final product’s intended usage, potters may opt for a certain fire method.
