The painter Bridget Riley’s assertion that ‘everything is there to be seen on the actual surface’ reminds us that close attention to a painting’s surface can reveal much about how it was made. For painters, making a drawing or copy after another artist’s work has long been a means of learning their craft. Through close observation of brushwork and texture, it becomes possible to reconstruct the decisions that form part of the finished picture. In the conservation studio, a similar form of looking takes place: conservators and conservation scientists develop a detailed understanding of pigment, medium, application and ageing to uncover how material processes contribute to a painting’s overall effect.
Few artists explored these material matters in paint as persistently as James McNeill Whistler (1834–1903). Over a long career he developed a highly distinctive approach to the painted surface, pursuing effects of atmosphere, economy and refinement through an ongoing investigation of what constituted a finished work. The articles in this issue emerge from the research project Whistler’s Finish, which for the first time addresses these questions through evidence gathered from the paintings themselves.1 Funded by the Lunder Foundation and in partnership with the Colby Museum of Art and the Hunterian, University of Glasgow, the project brought together curatorial, conservation and scientific research. Playing a central role in Tate Britain’s 2026 exhibition James McNeill Whistler, the research is expanded in this special issue. It is introduced here by the project’s principal investigators, Jane McCree (Conservation Manager, Paintings, Frames and Workshop), Joyce H. Townsend (Senior Conservation Scientist) and Carol Jacobi (Curator British Art, 1850–1915), who played a central role in shaping this special issue. As well as overseeing the eight articles emerging from the research project, McCree and Townsend contributed their extensive knowledge and expertise in defining the open call and reviewing submissions.
The exhibition at Tate Britain sought to encourage close looking by bringing this research into the gallery, engaging new audiences with material questions such as how the works had been made and the way they have changed over time.2 Paintings such as Miss May Alexander 1874–5 (Tate N05964) and Nocturne: Black and Gold – The Fire Wheel 1875 (Tate N03419) appeared following extensive conservation treatment, including the removal of discoloured varnish that had obscured their original tonal subtleties. Visitors were introduced to Whistler’s signature ‘sauce’ – the ingredients of which are identified in this issue by Georgina Rayner, Sophie Lynford, Katherine Eremin and Saffie Patel – that he used to dilute paint into the luminous washes that make his pictures appear to glow.
In the exhibition’s first room, a vitrine including a palette and selection of brushes accompanied portraits of Whistler’s model and romantic partner Maud Franklin. The wall text wove together material knowledge with an invitation to look closely at the painted surface:
Whistler created the folds of her skirt with a stiff, flat-ended brush. He pressed harder against the canvas to deepen the shadow at the hem. He chose softer brushes for the face and a smaller round-headed brush when he came to paint the tendrils of her hair.
It continued by drawing attention to the texture of the paint:
Thin, dry strokes suggest highlights on the rough fabric of the skirt. The background shadows are washed in like watercolour, with oil paint so liquid that it has dripped. The velvety, matte texture and soft, dark colour suit Franklin’s mysterious pose.
Whistler’s own writings and speeches on the topic appear across the articles, both those emerging from the research project and contributions beyond it. Archival research into Whistler’s notebooks, draft publications and court documents informs Deborah Lam’s investigation into Ruskin’s and Whistler’s understandings of finish, while Joyce Hill Stoner unearths treasures from the artist’s correspondence to support her reading of the friendships and disagreements we find reflected in the techniques and finish of Whistler’s paintings. Two articles on frames shed light on Whistler’s broad understanding of finish as a sense of unified harmony, or perfection, that increasingly included innovations in framing.
Whistler is joined in this issue by two other painters who write, Bridget Riley and Lisa Milroy. We return to Tate’s conservation studio for a technical analysis of Riley’s work, threading together her own reflections on making and finish with technical analysis of two of her paintings from the 1960s.3 Milroy, meanwhile, picks up on Stoner’s invitation to ‘read’ more than just paint into the surfaces of pictures. Her essay reflects on her search for new surfaces and supports for painting. Moving between observation, memory and making, she considers how emotion and experience shape the handling of paint, describing painting as a process of continual experimentation and a ‘continual play of loss and gain’.
The articles in this issue demonstrate the value of looking closely. Whether through technical examination, conservation research, art historical investigation or artists’ own reflections on practice, they return us to the painted surface as a rich source of knowledge about how works of art are made and experienced.
