  • Complexing agents and ceramic production: what they are and how they work
    2025/04/14
    Complexing agents are capable of catching multivalent cations present in suspension to prevent them from negatively affecting the ceramic process.

    They are responsible for one of the main mechanisms underlying the deflocculation process: complexation.

    Complexing agents (or chelating agents) are chemicals that bind to specific ions (such as calcium, magnesium, iron, etc.), forming stable complexes.

    This property allows them to "sequester" metals, making them less reactive or preventing their precipitation in solutions.

    These are simplified and very short descriptions of this particular category of additives.

    The episode takes a closer look at the mechanisms enacted by these substances within the ceramic production process, highlighting their functions, benefits, and sometimes, risks.

  • Relief surfaces and ceramic production (3D effects): methods and techniques
    2025/03/31
    The topic of non-planar surfaces, which develop on multiple micro-levels and are sometimes improperly identified as 3D surfaces, plays a crucial role in giving ceramic surfaces not only a more natural appearance but also a broader and more extensive expressive potential.

    This is not a new requirement: it took its first steps with the help of traditional technologies, but it has found new momentum with the arrival of the latest digital techniques.

    The episode offers an overview of the main methodologies currently used to achieve textured surfaces, delving into the chemical mechanisms that occur on the surface and contribute to producing the desired effects.

  • Preparatory stages of the digital printing process: from files to ceramic support
    2025/03/17
    In the previous episode (#45) we discussed the technical aspects of digital printing systems in relation to ceramic bricks.

    This second part looks at the necessary preparatory work for the printing phase, going through the various steps involved in preparing a print file.

    Regardless of the media on which you will work.

    Some key words: standardized lighting, colorimeter, spectrophotometer, linearization, chart...
