Classification: CPC C  G | IPC C  G

Claim 13:
14. A system for detecting an inclusion in glass, the glass including a base glass composition comprising:, Ingredient
wt. %

SiO2
67-75%

Na2O
10-20%

CaO
 5-15%

Al2O3
0-7%

K2O
0-7%

the system comprising:
at least one source for directing energy toward the glass, the at least one source being located above the glass and being oriented to cause reflectance as a result of the directed energy; and
a processor configured to determine whether an inclusion is present in the glass based on at least an analysis of at least one of an emitted value, a refracted value, a re-emitted value, a transmitted value, and a reflectance value obtained in the infrared (IR) spectrum from the glass, the emitted value, the refracted value, the re-emitted value, the transmitted value, and the reflectance value being obtained at different wavelengths.
