Lubricants for ceramic glazes are additives developed to improve the workability of aqueous suspensions during glazing. Their action reduces friction between solid particles, promoting a more uniform glaze distribution and helping to prevent surface defects.

In addition to their lubricating effect, they also act as anti-drying agents, maintaining consistent moisture in the applied layer and preventing premature drying, cracking, or irregularities.

In some cases, they also help preserve the rheological stability of the suspension, ensuring consistent performance both during application and storage.
Thanks to their versatility, lubricants can be used in different types of glazes, adapting to various production requirements.
