Understanding the Kiln: How Firing Brings Your Creations to Life

The magic of pottery doesn’t end when you shape your clay into something, but it’s just the beginning. To truly bring your creations to life, they must pass through the transformative fire of the kiln. 🔥🔥

But what exactly happens during firing, and why is it so important?

The Science Behind Firing

The kiln is where soft clay is permanently transformed into hard ceramic. This process involves extreme heat—typically reaching over 1,000°C—causing a chemical reaction in the clay that removes all remaining water (the 'chemical' water bonded in with the clay particles) and strengthens the structure. This is a one way journey! Once you reach these temperatures there is no turning back....

The first firing, known as the bisque firing, removes impurities a nd water and hardens the piece, making it durable enough to handle for glazing. This is where the clay becomes ceramic. The second firing, the glaze firing, bonds a glaze to the surface, creating a smooth, glassy finish which can be dry, matte or glossy.

Why Firing Matters

Without firing, pottery would remain fragile and unable to hold liquids or withstand daily use. It would just fall apart and return to its wet clay-like state It’s in the kiln that your work gains its strength, durability, and, most importantly, its unique character.

A World of Possibilities

Kilns also allow for incredible creativity. From the soft matte of a low-fire glaze to the brilliant shine of high-fire finishes, the possibilities are indeed endless. Advanced techniques like oxidation and reduction atmospheres can further transform colours and textures, making each piece truly one of a kind.
