Suspending agents are chemical additives, available in both liquid and solid form, used in the preparation of glazes, engobes, and ceramic slurries. Their role is to increase the yield point of aqueous suspensions, helping to maintain stable rheological properties and preventing particles from settling.

This keeps the solids evenly dispersed, avoiding unwanted deposits and ensuring a uniform distribution of raw materials. The result is smoother processing and greater consistency in the quality of the finished product. The stability they provide also allows semi-finished materials to be stored for extended periods without significant changes in viscosity or rheological behavior, which simplifies production management and supports efficient line operation.
