5 Day Masterclass
Monday 15 - Friday 20 February 2027
9.00am - 4.00pm
Visiting from the UK, sculptural artist Joanna Manousis will be teaching a specialist workshop at Studio4 in February 2027. This is an excellent opportunity to learn a new range of techniques from an established international glassmaker.
Residual Forms: A Comprehensive Guide to Core-Cast Glass Methods
This five-day class explores the creation of residual forms and internal cavities within kiln-cast glass, introducing two principal approaches: surface-core and hanging-core techniques. Drawing on over 20 years of research and studio practice, Joanna Manousis will demonstrate how intricate, three-dimensional spaces and impressions can be formed within solid glass.
Through demonstrations and hands-on making, students will explore the manipulation of clay, wax and found objects to develop original forms, alongside the construction of silicone mother moulds and refractory cores. Techniques will include hollow-wax construction, multi-part investment mould-making, sprueing and venting, water displacement, glass preparation, kiln-firing schedules, de-investment and cold-working.
Students will gain an understanding of the complete casting process, from initial model-making through to revealing and refining the internal surfaces of their finished glass forms.
The class is suitable for all levels, although previous experience in kiln-cast glass is preferred. It offers an opportunity to develop a substantial range of mould-making skills and explore new possibilities for creating complex forms within glass.
Joanna Manousis - Artist Bio
British-American artist Joanna Manousis creates sculptural objects and installations in glass, mirrors and mixed media that explore perception, memory, human emotion and the passage of time. Through the transformative properties of light, reflection and material, her work examines the relationship between our internal experiences and the worlds we construct around us.
Manousis holds a PhD in Art and Design from the University of Sunderland, where her research at the National Glass Centre investigated the creative potential of three-dimensional mirrors within cast glass and their application in contemporary visual art practice. She also holds an MFA in Sculpture from Alfred University, New York, and a BFA in Glass from the University of Wolverhampton, England.
Her work has been nominated for the Louis Comfort Tiffany Foundation Award and the Bombay Sapphire Award for Excellence in Glass. She is the recipient of the Margaret M. Mead Award and the Hans Godo Frabel Award, and a QEST Scholar and Homo Faber Master Artisan. She has participated in internationally recognised residency programmes at the Toledo Museum of Art, the Museum of Arts and Design, the Corning Museum of Glass and Cité Internationale des Arts, Paris. Her work has been exhibited internationally at Design Miami, Art Basel Basel, FOG Art + Design, Glasmuseet Ebeltoft and the British Glass Biennale. Manousis has worked, studied and taught in Japan, the United Kingdom, the United States and Australia.
