Preventive Techniques
Traditionally, preventive measures in glass manufacturing involve maintaining critical process parameters within established operational limits. Thus, it is essential to inspect, regulate, and standardize all parameters from the grain size and composition of raw materials to the packaging of the final product. Additionally, ensuring the proper design and maintenance of all equipment, from storage depots to the racks in warehouses, is crucial. These parameters are dictated by the requirements of the process and the application of statistical tools. The melting process, for instance, includes parameters such as glass composition, melting temperature, furnace pressure, and the redox number of the molten glass, among others. Additionally, primary processes are often affected by variations in utilities such as flow rate, purity, pressure, temperature, and potential contaminants, along with issues related to supply interruptions and cutoffs. This approach ensures process stability as a crucial requirement for glass manufacturing.

Handling Defects and Incidents
Traditional problem-solving in this context requires a high level of experience and a deep repository of accumulated knowledge to effectively investigate these defects and pinpoint their origins at an early stage.
Currently, the effectiveness of addressing and resolving defects in glass manufacturing largely depends on the training of the personnel involved. In this traditional model, it is essential to select individuals who have undergone extensive training, demonstrated high accountability, and retained the knowledge better than their peers. When a defect arises, an experienced glass technologist must supervise and delegate specific roles: one person to identify the defect type, another to recognize symptoms within the process, and a third to detect recurring patterns, including time intervals and locations on the glass article. After these roles are assigned, substantial effort is required to pinpoint the exact root cause and location of the defects before remedial actions can be implemented.
