Based on years of the reliable and historical data ，statistical analysis was used to obtain the key elements of colorless and transparent glassware decolorization quality level assurance ，the ways to reduce melting energy consumption in natural gas furnaces，and the solutions for adjusting decolorant dosage adopted in the process of energy performance improvement，respectively. This analysis idea and method can be used for reference by related enterprises，and the valuable reference for the related glassware manufactures to develop out the better proper methods to carry out the product quality improvement and the energy consumption performance increase.
