LOW-TEMPERATURE GLAZES, CHEMISTRY AND FORMULATIONS | Claudio Gardenghi
21-22-23-24-25 May 2025
Course focusing on making your own low-temperature ceramic glazes.
In this particular course, you will learn how to formulate or modify the aesthetics of lowtemperature glazes.
Low-temperature ceramic objects often need a “cover”. which is called a glaze, required to make the ceramic object water-resistant and aesthetically conform to what is desired.
What is needed to make a glaze? What frits and raw materials to combine to make it? How to modify a ready-made glaze? And how to proceed from test to test to achieve the desired effect?
The teacher Claudio Gardenghi, an expert with over forty years of experience in some of the most important ceramic colour factories, will introduce participants to the world of lowtemperature glazes, also giving space for some personal research.
In fact, thanks to the small number of participants, it will be possible both to work on bases provided by the organisation and to analyse, replicate or correct glazes deriving from participants’ own research (“as long as they are suitable for low temperature”).
All results will then be presented and shared with the class.

Imparare le tecniche di foggiatura e la cottura delle terre
Quando ci si avvicina al mondo della ceramica spesso si incontrano le prime difficoltà già nella fase di modellazione proprio per mancanza di competenze nelle tecniche di foggiatura dei manufatti. Gli impasti ceramici e le argille possono essere lavorati in diversi modi e in questo corso di base ci proponiamo di introdurvi ad alcune delle tecniche fondamentali come il colombino, la lastra, la stampatura e il colaggio.
La scelta del tipo di argilla da impiegare ed individuare la migliore tecnica di modellazione per la produzione delle forme sarà di basilare importanza per avere successo nel portare a termine i vostri progetti ed evitare perdite di tempo e di denaro.
Il corso non è finalizzato alla realizzazione di oggetti finiti ma si limita alla produzione in libertà di esperienze costruttive, tattili e di cottura sempre sotto
la guida del docente.

A sea of melted glass
3 - 4 february 2018
A Faenza, sul finire degli anni 60′, Guerrino Tramonti pratica una tecnica ceramica pittorica denominata “A grosso spessore”. Si tratta di una ceramica che prevede la formazione di uno spessore alto di vetro liquido (cristallina) che allaga entro una superficie piana definita da una bordatura.
Durante il corso saranno fatte esperienze con l’inserimento di smalti, ingobbi, fritte colorate, vetri da vetraria e fili metallici. Saranno impiagate anche le “terre sigillate” che saranno applicate sulle cornici a formare rugginose e brillanti cortecce. Le forme in argilla già biscottata saranno fornite dall’organizzazione.
Programma: Applicazione su biscotto di ingobbi naturali del genere terra sigillata – applicazione al centro delle forme di smalti, vetri in frammenti ecc e copertura di vernice trasparente o colorata in rame con varie tecniche di miscelazione – cottura notturna – descrizione dei prodotti usati – esempio di preparazione di una terra sigillata – nelle foto alcuni esempi di opere realizzate da G. Cimatti
Le forme saranno realizzate seguendo le indicazioni del docente, saranno cotte e consegnate entro i tempi del corso stesso.
Il corso di 14 ore inizia alle ore 9.00 del sabato e termina alle ore 16.00 della domenica.

Immediate transparency workshop, slip porcelain without usa of mold and in a single-firing
Transparency is one of the most important qualities of porcelain and usually, requires a prolonged, precise and very accurate processing to obtain a fine beauty piece highlighted by the translucenty. This course allows you to develop two simple and immediate techniques that will facilitate and strengthen creativity to develop many projects without the use of large resources and experience in the field of porcelain techniques. We will use slip porcelain without the use of molds and with a single-firing.
PROGRAM:
Totally practical lessons, preparation of the material and basic forms.
Use of slip porcelain and construction with two totally different techniques.
Surface treatment, controlled drying and finishing.
Methods to avoid deformation and breakage during the process and all the special features of the specific firing for this technique.
Recover broken complex variations of the techniques and the surface with the use of color introduced into the slip the porcelain.
Production of pieces to project in small series for use or decoration. pieces or cracks with specific recipe.
Finally, more co.
