JOSEP MARIA MARISCAL: THROWING & CRYSTALLINE GLAZES
11-17 JUNE 2026
We are delighted to welcome internationally renowned ceramic artist Josep Maria Mariscal for an immersive 7-day pottery experience.
This workshop is divided into two three-day parts, which can be joined separately or combined for a full week of skill-building and inspiration:
1) Throwing Workshop (11-13 June)
2) Crystalline Glazes Workshop (15-17 June)
Whether you want to refine your throwing techniques, explore the unique beauty of crystalline glazes, or both, this is a rare opportunity to learn directly from one of the most respected figures in contemporary ceramics.
About Josep Maria Mariscal
Josep Maria Mariscal comes from a family of potters in La Bisbal de Empordà, Spain. He began throwing clay at a very young age under the guidance of his father. A Master Potter recognised by La Generalitat de Catalunya and a member of the International Academy of Ceramics in Geneva, Mariscal has spent decades exploring the worlds of crystalline glazes, raku, and advanced wheel-throwing techniques.
Since opening his own studio in 2003, he has conducted workshops worldwide – from the USA to Australia – and played a key role in organising Cristalls2013, Spain’s first crystalline glaze convention. His work is characterised by technical mastery and a pursuit of unique, one-of-a-kind pieces.
Course Descriptions
Part 1 Throwing Workshop 11-13 June (three days)
This intensive wheel-throwing workshop focuses on creating more complex, advanced, and larger-scale vessels, refining precision, and improving efficiency at the wheel. Mornings begin with detailed demonstrations of Mariscal’s techniques, followed by hands-on practice under his guidance.
Daily Schedule
9 am – 6 pm including lunch break
Generally, the first two days focus on throwing forms, double walls, and necks, while the third day is dedicated to trimming and creating textured pieces.
Please note: Josep Maria Mariscal does not follow a rigid day-by-day programme. Instead, he adapts the content to the group’s level and needs, ensuring that all participants progress effectively. All key techniques will be covered, including double-walled forms, narrow necks, and large pieces, but the pace and exercises will be tailored to support the group’s development.
Extra Opportunity
The fourth day (14 June) is a rest day and will be used for bisque firing of test tiles, as well as optional free throwing for those continuing with the crystalline glaze workshop.
