| abstract |
the invention relates to a method and / or system for detecting inclusions (e.g. nickel sulfide-based inclusions / defects) in soda-lime silica-based glass, such as float glass. in certain case examples, during and / or after the glass making process, after the stage in the flotation process where the glass sheet is formed and floats on a molten material (eg, tin bath) and is cooled or allowed to cool by lehr annealing, the light is directed on the resulting glass and the reflection of various wavelengths (for example, red and blue wavelengths) is analyzed to detect inclusions. |
