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.

However, foam formation can disrupt production, leading to defects and lower efficiency.
This episode dives into the world of foaming phenomena, exploring how they arise and how they affect the properties of suspensions.
We discuss surfactants, which can encourage foam formation, and defoamers, which h...
In this episode, we break down the key causes, explain how they arise, and share practical ways to prevent them.
For a deeper dive into the topic, check out episode #39.
This episode answers exactly these questions. Without delving into complex details, it presents a few key concepts to help navigate topics such as viscosity, material behavior, and process control.
It’s a first step toward understanding the practical role of rheology in improving quality and production efficiency. In ten minutes.
It can also be understood as the process through which effective contact is established between a liquid and a solid.
In some cases, solid surfaces exhibit low wettability—a characteristic that, while not inherently problematic, can lead to significant issues in the ceramic industry.
When raw ceramic bodies or suspended parti...
When conductivity levels go unchecked, they can compromise the quality of the final product, cause corrosion in equipment, or alter the reactivity of the materials used.
In this episode, we explore why continuous monitoring is essen...
We focus on dispersants and binders, compounds that give the glaze the right balance of cohesion, stability, and flow. But there’s no one-size-fits-all solution here: the type of additive must be tailored to the specific application...
At the core of this shift are ceramic digital printers—advanced machines that use inkjet technology to precisely apply both functional and decorative materials.
While the focus is often on inks and printing performance, there’s another category of fluids working quietly behind the scenes: maintenance f...
These substances, often polymer-based, act on a chemical level by creating bonds between particles, increasing the mechanical strength of the mixture.
In this episode, we explore what they are, how they work, and why they are essential in modern ceramic processes.

This glaze can serve multiple functions, but it primarily protects the underlying decoration and imparts specific technical and aesthetic properties to the surface.
This episode focuses on this particular class of glazes, taking a closer look at the key functions and rheological characteristics (among others) that t...
We posed a few simple questions to artificial intelligence, asking it to write a short text about chemistry with complete freedom to choose the themes and highlights.
The result? Amusing, sometimes absurd—mostly accurate, but not always.
As we know, Large Language Models (the t...
This action, which occurs through the breaking of the molecular structure of the compound (in our case, silica) by certain ions, affects several factors and must be carefully calibrated each time to achieve the desired result.
Some of the areas influenced ...
The ceramic industry, too, must adhere to rules and parameters that enhance productivity while avoiding any form of waste.
However, process interruptions—representing the most extreme scenarios—can be triggered by numerous factors and can occur at various stages along the production line.
Even the digital printing process,...
For example, process water forms the basis of different production phases and ensures their proper development.
However, not all waters are the same.
Depending on its source, water can have very different properties, which may make it suitable or unsuitable for a specific process.
In general, water qualit...
Available in both liquid and solid forms, these products act within the suspension to ensure the right balance.
There are various mechanisms that can be employed to properly maintain the solid phase of the mix...
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 "seques...
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 digit...
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...
These techniques are suitable to produce traditional products for the existing market.
What added value does digital printing offer in this field?
However, this parameter is not always easy to manage, especially if we consider the fluctuations promoted by seasonability.
The episode addresses the topic with the help of specific examples, highlighting the main scenarios and the...
