There are varieties of stone defects that can arise from glass production.The use of polarized light microscopy can initially determine the type of glass stones ，but the sample processing is inefficient and the composition of the stones cannot be specifically analyzed by this method.The siliceous crystalline nodules， aluminum refractory nodules and zirconium refractory nodules are taken as examples for analysis using scanning electron microscopy and energy dispersive spectrometer，which can quickly identify the type and determine the composition of glass stone，then infer its formation causes.So this method can adjust production timely and accurately and solve the glass product problem.

The tempering process parameters of the tempered opal glassware were recombined by the practical application of the quality statistical techniques.The new optimized combinative process parameters not only raised the mechanical shock resistance on rim，also reduced the natural gas energy consumption per unit product.The improvement project supported the daily actions concerned with product quality continuous improvement and energy savings，meantime，it can be as the valuable reference to other domestic glassware manufactures.

In order to reduce production risk ，improve stability of production ，ensure the safe operation of power supply and distribution system and achieve efficient use of energy in the float glass factory ，a practice plan of island operation and maintenance and emergency response for waste heat power generation and oil- electric system has been developed.Through the management of operation and implementation of maintenance and emergency response measures，the stable operations of waste heat power generation and oil-electric system were achieved.Once the power supply fails，waste heat generation and oil-electric systems will immediately switch on to continue power supply so as to ensure the smooth production process.Through the implementation of this practice plan，the safety and stability of the power supply and distribution system in the float glass factory have been improved and fluctuations and risks in the production process have been effectively controlled.Moreover，the stable operation of waste heat power generation and oil-electric system also contributes to the effective use of energy and improves the economic benefit of the float glass factory.

In the production process of TFT-LCD substrate glass，in order to eliminate the sharp edges and reduce edge stress，it is necessary to grind the four edges of the glass.Because the grinding process generates a lot of heat instantaneously，a large amount of water cooling is used to overcome quality defects such as edge burning and broken.In order to ensure cooling effectiveness and avoid pollution on the glass surface ，it is required to use the expansive pure water with 10 megohms for grinding cooling.The wastewater recycling and reuse system was developed to reduce pure water consumption and renovation experiments were conducted on the G5 generation production site.By comparing the water quality and glass processing quality before and after the renovation，it was shown that the amount of pure water used had been significantly reduced，the recycling water had no negative impact on the surface pollution of glass，and edge defects can also meet quality control requirements.After the renovation，the production cost has been greatly reduced，which has important practical application value.

Large flat enamel has many advantages as a new type of architectural decorative material，but its manufacturing requirements are high.The hanging-fired method ， production process ， and enamel layer thickness of large flat enamel may all lead to product deformation.The influence of material properties， production processes ，and thermal expansion coefficient of enamel glaze on product deformation during the production process of large flat enamelwere investigated.The study shows that there are many factors that cause product deformation，which need to be comprehensively considered during the production process.In order to reduce the deformation of large plate enamel ， should ensure that the firing process of the product heat uniformity，to avoid rapid heating and cooling，while optimising the structural design of flat enamel，the use of more suitable materials and strict control of the external environment and other measures can be achieved to control the product deformation purposes.

Light transmission property is a key quality characteristic of photovoltaic glass products.The current testing standards and methods for the light transmission property of photovoltaic glass were mainly discussed ， listed the problems encountered in the process of the light transmission property test，calibrated and verified the light transmission property measuring system from two perspectives，such as traceability of the measuring value and its source tracing ， equipment management and maintenance ， in comparison with the evaluation and calibration methods of the measuring system.It was briefly described the management and maintenance of photovoltaic glass light transmission property measurement systems from two perspectives such as internal photovoltaic glass manufacturers and external PV module enterprises ， citing the methods and theories of measurement and evaluation ， and organizing the management methods of light transmission property measurement systems from a systematic perspective.By analyzing and sorting out the deficiencies and solutions of the current measurement system and strengthening the management of the light transmission property measurement system，it has certain reference value for rapid detection and evaluation of the light transmission property of photovoltaic glass.

Aiming at the problem that it is difficult to use microscope to collect pictures from the large-size cutting sections of TFT -LCD glass，a corresponding glass section analysing equipment was designed，and the sliding spiral mechanism in the equipment was simulated and analyzed by Adams software and its structure was optimized.The results showed that the glass section analysing equipment was easy to operate and can quickly obtain the defect picture of large-size glass edge material section.After optimization and improvement ，the added torque value of sliding screw mechanism was reduced twice than that before optimization and improvement.
