Stacking is the arrangement of ceramic pieces inside the kiln for firing. During bisque firing (first firing), the pieces can be stacked inside each other, since they do not have glaze that can melt and stick together.
This method maximizes kiln space and is especially useful when firing large numbers of pieces. However, in glaze firing, the pieces must be separated to prevent them from sticking together, as the glaze melts during the firing process.
Correct placement of the pieces is also important to ensure uniform firing and prevent defects in the finished pieces. Good stacking optimizes the use of space and fuel in the kiln, which is key to the efficient production of ceramics.
Interesting Fact
In China's traditional dragon kilns, which were long, elongated kilns, parts were stacked precisely to maximize kiln capacity, sometimes firing thousands of parts at a time.
Helpful Tip
Place the larger, heavier pieces at the bottom of the stack, and the lighter, more delicate pieces at the top, this helps maintain stability and ensures more even firing.
