A glass-ceramic includes glass and crystalline phases, where the crystalline phase includes non-stoichiometric suboxides of titanium, forming bronze-type solid state defect structures in which vacancies are occupied with dopant cations.

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.
