Abstract
A method and/or system is provided for detecting and/or identifying inclusions (e.g., nickel sulfide based inclusions/defects) in glass such as soda-lime-silica based float glass. In certain example instances, during and/or after the glass-making process, following the stage in the float process where the glass sheet is formed and floated on a molten material (e.g., tin bath) and cooled or allowed to cool such as via an annealing lehr, energy such as infrared (IR) energy is directed at the resulting glass and reflectance at various wavelengths is analyzed to detect inclusions.
