Eight colored glasses from Fire and Light Originals (FLO) and three container cullet glasses were characterized for the viscosity, density, and thermal expansion, glass transition temperature, dilatometer softening temperature, color chromaticity, Fe(II)/Fe(total) redox ratio, and chemical composition. The results of the characterization were used to evaluate the options for the glass formulation development of colored glasses aimed at increasing the use of recycled container glass cullet. Out of several options considered, the possibility of using clear cullet for FLO’s Citrus colored glass was selected and investigated in this study. It was shown that it is possible to use clear cullet to produce Citrus glass at the cullet oxide ratio of 90 mass% and the final color can be adjusted by controlling the nitrate level and alkali concentrations. From the present study, recommendations for further development efforts are provided to increase the container cullet usage or to replace partially or entirely the clear cullet by the amber cullet.
