Step 3: Cleaning. Once inspected, the glass is cleaned to remove dust and anything else that may contaminate it during the tempering stage. Sharp edges are also smoothed using a mild abrasive. This will prepare the glass for the next step of the tempered glass manufacturing process, which is heating it in a furnace.
