Effect of green colour on glass quality

Abstract EN

The study of green color in glass has a special importance on the glass quality, specially the effect of ferrous oxides content of the limestone.

Results obtained that there was a reduction in green colour when different ferrous oxide contents in the limestone were added in glass production, limestone sources from two quarries, and the first contains 0.67 % ferrous oxide and the second possess less ferrous oxide.

Reduction of green colour showed higher transmittance12 % and it could be suggested that reduction of ferrous oxides content in the limestone is of special importance on the optical properties of glass.
