A kiln is basically a REALLY hot oven used to finish (or fully set) ceramic clay pieces. Ceramic clay vessels are typically fired twice in a kiln - first without glaze after your pottery has air dried completely (called the “bisque firing”) + again after glazing and/or underglazing (called the “glaze firing”) - note that Underglaze may be added before EITHER firing, while glaze may only be added after the bisque firing. Get yourself our Underglaze add-on to enhance your piece with color.Firing your ceramic clay creation helps make it more durable, waterproof + (when glazed) food-safe. The process also brings out the color + shine of any applied glaze or underglazes. In the kiln, your piece reaches a temperature between 2167-2205° F (way hotter than your home oven!), so you’ll need to visit a professional pottery studio for assistance.
