Initial stages of float glass corrosion

The differences between the corrosion process of the bath and the top side of float glass and the dependence on the corrosion process on the thickness of the glass could be demonstrated by ellipsometric measurements of defined corroded float glasses. The effectiveness of different cleaning procedures on corroded float glass surfaces is discussed. Ellipsometry can help determine suitable separating agent for the storage of float glass sheets.
