Apparently invisible. Chemistry in ceramics.

By: Zschimmer & Schwarz Ceramco
  • 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.

  • Chemicals & seasonality: problems and suggestions
    Dec 23 2024
    After addresing the impact that seasonality can have on the the fluidization of ceramic mixtures and on bacterial proliferation within semi-finished products, this second part of the episode 41 tries to show and explain the consequences that temperature changes may produce on the drying time of ceramic suspension, leading to alterations that often force producers to revise the parameters of the glazing line.

    After offering the usual suggestions to handle the problem, the episode ends with a focus on the solubility of surfactants that can be also susceptible to seasonal and temperature changes.

  • Chemicals & seasonality: problems and suggestions
    Dec 10 2024
    In ceramics, the use of chemicals plays a fundamental role in providing the final product with high technical and aesthetic results and in promoting a proper application process.

    However, their actions can be sometimes less effective or compromised.

    There are several reasons for this performance change and seasonality is surely one of the most interesting.

    Through a series of examples, the episode addresses the actions that should be taken to prevent the temperature to negatively affecting both processes and products.

  • Glaze and grit suspensions: differences & similarities
    Nov 25 2024
    Glaze and grit suspensions are made up of a liquid part (usually made-up of water and one or more rheological chemicals) and a dispersed solid part.

    However, these two different suspensions show a lot of differences that may lead to very contrasting results, also implying a different approach about chemicals, both during the grinding phase and along the glazing line.

    From this point of view, all chemicals involved must be marked by specific features according their intened use. What do we need to know about the subject?
