About Apparently invisible. Chemistry in ceramics.
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.
Dispersants for ceramic bodies: rheology control and slip management
In the wet preparation of ceramic bodies, dispersants play an essential role in controlling slurry rheology, allowing high solids content to be maintained while ensuring flow properties compatible with the production process.
In this episode, we examine the main factors affecting slurry rheology: viscosity and thixotropy, raw material characteristics, composition of the aqueous phase, and the different chemical families and mechanisms of action of deflocculants. We also explore the role of dosage and the deflocculation curve, explaining why there is no universal solution and why the optimal working range must be determined experimentally for each specific ceramic body and process conditions.

Back meshing of large ceramic slabs: safety, strength, and process control
The growing use of large ceramic slabs, with increasingly larger formats and reduced thicknesses, has introduced new challenges in terms of processing, handling, installation and safety. In this context, back-meshing is a post-firing process in which a reinforcing mesh is bonded to the back of the slab, helping to retain fragments in the event of breakage while providing additional support during subsequent processing, handling and use.
In this episode, we explore the back-meshing process, from mesh selection and the role of the two-component polyurethane adhesive system offered by Z&S Ceramco to different application technologies and the cross-linking stage.
A journey through materials, chemistry and application technology to understand how mesh, adhesive and process need to work together to provide effective and reliable reinforcement.

Semi-finished media for solvent-based glues, inks and digital effects production
Producing digital inks, glues and ink effects for ceramic decoration is a highly sophisticated process that relies on the careful integration of multiple formulation components. Achieving consistent performance, long-term stability and reliable production quality requires the use of a range of specialized additives, each playing a critical role in ensuring proper product functionality and processability.
In this episode, we revisit the concept behind the DECOFLUX DP range: a modular additive platform developed to support ink manufacturers and ceramic companies that produce their own digital inks and glues in-house. From pigment grinding to final dilution, we explore how each element of the platform — from pre-optimized grinding media and universal dispersants to viscosity modifiers and stabilizing agents — has been designed to address the practical and evolving requirements of the formulation
