  • Summary

  • Aware of how complex the problems related to the world of chemistry applied to ceramic production processes can be, we want to share our knowledge with those who want to orient themselves or train for passion or profession.
    Through a simple and direct language, the podcast aims to be an educational space with a focus on products, applications and processes.
    The journey unfolds along the ceramic production lines.
    At each stage a topic.
    At each topic a critical issue.
    At each critical issue, when possible, a solution.

  • Sodium silicate & deflocculation of ceramic mixtures

    Sodium silicate & deflocculation of ceramic mixtures
    Jun 24 2024
    Sodium silicate is an inorganic substance that at room temperature it is in solid state.

    It is a chemical compound used in several areas of industrial production. In ceramics, sodium silicate is very effective within ceramic mixtures.

    Among the several effects it produces, it plays a very important role in terms of fluidization.

    The episode is about the function that this substance performs, highlighting its several properties and the benefits it promotes.

    With a focus on deflocculation of ceramic mixtures.

  • Ceramic firing cycle, emissions and chemism of digital inks

    Ceramic firing cycle, emissions and chemism of digital inks
    Jun 10 2024
    Polluting and odor emissions are two important critical issues that producers have been looking for some time with considerable attention.

    This is a problem that appears in the final stage of the ceramic production cycle, inside the kilns, but whose origin can be found in the previous application processes that mostly take place along the glazing line.

    Scenarios can be different but emissions are mostly produces by the use of digital glues and digital inks that, due to their particular chemism, can be considered the core of the problem.

    What do we need to know about it?

  • Foam formation within ceramic glazes: how to deal with it?

    Foam formation within ceramic glazes: how to deal with it?
    Apr 29 2024
    Among the several issues that may arise along the glazing line, the excessive foaming within glaze suspensions is one of the most frequent and problematic.

    The phenomenon is already visible on the surface of the glaze inside the stirring systems but consequences can persist even after the end of the production, that is after the firing cycle.

    Chemistry speaking, what is foam? What are the causes of its presence and what do we need to know to prevent its formation or to remove it in case of unexpected phenomena?
