Annealing

The process of controlled, slow cooling of ceramic (or glass) pieces after high-temperature firing. This process is essential for relieving internal stresses and strengthening the material. During annealing, pieces are cooled slowly to room temperature in a kiln or other controlled environment. The goal is to minimise thermal stress, making the piece more durable and less prone to cracking. Annealing is especially important when working with glass or ceramics formed at high temperatures, such as stained glass or certain ceramic objects.
