Porcelain and terracotta sculptures, though both rooted in ceramic art, exhibit striking differences in their firing techniques. Porcelain, made from refined kaolin clay, requires extremely high firing temperatures ranging from 1,200 to 1,400°C. This process vitrifies the material, resulting in a translucent, glass-like finish that is highly durable and non-porous.

In contrast, terracotta sculptures are crafted from coarse, porous clay and fired at lower temperatures, typically between 600 to 1,000°C. The lower heat preserves the material's earthy texture and reddish-brown hue, making it more susceptible to weathering but ideal for rustic artistic expressions.

The choice of firing technique also impacts the final artwork. Porcelain's high-temperature firing allows for intricate detailing and a polished appearance, while terracotta's lower firing temperature lends itself to a more organic, tactile quality. Understanding these differences helps artists select the right medium for their creative vision.
