In surveying Summer’s work over the years the constants and changes become apparent. Prevalent in his work is a deeply meditative character which does not involve only the outer forms but also the processes which develop out of his working methods. Above all, Roland Summer’s vessels manifest a special austerity which has to some extent in more recent times begun to dissolve. In spite of all the rigour and precision, the work does not appear cold, lifeless or dull. Through hardly visible irregularities, small shifts and movements, slightly diagonal instead of straight lines, underpinned by the irregularities and contingent smoke traces, the vessels always exude a liveliness and tension.
