Temperature measurement in the glass industry
When manufacturing glass, precise temperature measurements are crucial for the final result. Glass is used for a variety of purposes and can be shaped, tempered, colored, laminated, or treated to meet specific requirements.
In this process, accurate temperature measurement is of critical importance to optimize glass production and ensure the quality of the finished product. Accurate temperature measurement also helps control pollution and monitor safety.
How is temperature measured in glass production?
When measuring temperature in glass production, high temperatures are involved, and it is therefore important to have the right tools developed for the purpose. With infrared temperature measurement, you can safely and accurately measure the temperature and thus ensure the quality of the production.
Below you can read more about temperature measurement in different types of glass production.

Container Glass
Container glass is used for bottles, jars, and other containers. This type of glass has a higher content of water-insoluble oxides, which provides chemical durability against water, an important property for storing beverages and food.
Throughout the production process for container glass, there are several points where temperature measurements are important, including thermal imaging of the melting tank and monitoring of cooling in the annealing process.
Accurate measurements at critical points are essential to support consistent quality in the manufacture of container glass. At Hans Buch, you will find a range of advanced instruments with high precision – specially designed for the glass industry to deliver the desired results.
Batch
Batch is a sand-based mixture of minerals – often mixed with waste – that is melted in the furnace to create molten glass.
This mixture enters the furnace, and in this context, monitoring the temperatures at the furnace entrance is important. Temperature measurement helps confirm uniformity, ensuring that the batch melts at the expected time in the process. It also helps monitor the batch for any impurities that may affect the quality of the finished product.
It also helps extend the durability of your tools, as temperature measurement can prevent damage to the melting tank from overheated batch.
Temperature Monitoring in the Melting Tank
The highest temperatures in the glass production process occur in the melting tank. Real-time monitoring of these temperatures is crucial for the efficiency of the application and the quality of the product. It is important to be able to study the entire interior of the tank to detect any structural damage.
When monitoring the condition of the melting tank, it is possible to detect and repair internal damage, which improves energy efficiency and reduces unplanned downtime. Thermal measurements in the melting tank also support process efficiency and consistent glass quality.
Regenerators
Regenerators are heat exchangers, meaning they alternate between receiving heat and transferring this heat back to the combustion air. Regenerators are used to preheat the air for use in the melting tank.
This area of the tank is extremely important for the melting process and is vulnerable to damage from prolonged heat exposure. There is also a need to monitor emissions at the regenerator to ensure compliance with environmental regulations.
Accurate measurements in the regenerator’s high temperatures support the efficiency of the melting process. They also provide early warning of any incorrect or unbalanced firing, which can affect product quality and energy consumption.
Flue Gas in Glass Production
The combustion processes used in glass production often produce flue gas emissions, which are subject to strict environmental regulations. To ensure compliance with the regulations, glass manufacturers are required to monitor and control emissions.
