Optimizing Glaze Flow Rate in Ceramic Production with Sodium Tripolyphosphate


Understanding the Glaze Pulp Challenge


In the evolution of ceramic production technology, the stability of glaze flow rate is a critical factor. Producers often face challenges with uneven glaze flow, especially in raw glaze, which can become unstable over time and resemble tofu flowers. This instability hampers the production efficiency and quality of ceramic products.


The Magical Effect of Sodium Tripolyphosphate


Sodium Tripolyphosphate (STPP) is a powerful additive known for its water-reducing and dispersing properties. It plays a crucial role in ceramic production by diluting the glaze pulp and enhancing the slurry’s liquidity under low moisture conditions. This ensures that the glaze slurry remains stable and does not deteriorate easily, thus improving the overall quality of the ceramic glaze.


Experimental Verification and Additive Selection


Extensive experiments have shown that adding STPP to the glaze slurry maintains its stability and consistent flow rate over time. However, the selection and dosage of STPP must be tailored to different types of glazes through experimentation. This helps achieve an optimal balance between the proportion of STPP and the desired liquidity of the glaze.


Enhancing Glaze Intensity and Reducing Damage


Appropriate use of STPP not only increases the intensity of the glaze but also minimizes damage to the glazed surface. This makes the glaze more suitable for various ceramic production techniques, including throwing. STPP has shown particularly impressive results in the production of antique bricks, enhancing their quality and durability.


Technological Solutions to Glaze Problems


With the integration of modern technology, STPP offers a viable solution to the longstanding problem of unstable glaze flow in ceramic production. Its application opens up new possibilities for optimizing ceramic production processes and supports the development of the ceramic industry by providing a reliable and effective additive.




Sodium Tripolyphosphate is an indispensable additive in ceramic production, offering significant benefits in stabilizing glaze flow rate, enhancing glaze intensity, and reducing surface damage. By understanding its mechanism and conducting thorough experiments, ceramic producers can optimize their processes, improve product quality, and address longstanding production challenges. This advancement not only resolves existing issues but also paves the way for further innovations in the ceramic industry.
