Basics of Glass Annealing

In technical glass production, molten glass is pressed and it rapidly cools as it is removed from the mold. This rapid cooling creates internal stresses within the glass piece. When the glass finally cools to room temperature, stresses in the glass can potentially cause spontaneous breakage. Glass annealing is a controlled process of slowly cooling…
