The Design Museum

"FUTURE TALKS is a highly recognised and established forum for interdisciplinary lectures, workshops and discussions on modern materials and technologies and its impact to the world of conservators, scientists, designers, artists and design and art galleries. The professional treatment of surfaces is often the ultimate and most difficult challenge for the conservator of modern heritage. Besides a profound knowledge of materials and technologies, the conservator needs to have the necessary skills available to handle these challenges in a most reasonable, appropriate and professional way. The FUTURE TALKS 019 conference is focusing on the evolution and role of modern surface technologies in design and art, the diversity of visual qualities and appearances, the aging phenomena and its public reception, scientific research, documentation techniques, decision-making, and the practical conservation treatments involved."


Speaker: Sylvia Jeffriess, Associate Conservator


Lecture: Brian Belott’s frozen sculptures. Condition state as material surface in contemporary art

The Valuation of Fine Art: Damage and Loss Cases - the necessity of specialized categories of expertise


The valuation of fine art and design for the purpose of damage/loss appraisal reports is a delicate matter composed of numerous voices within tiers of the art trade community. Choosing the right candidate to write a comprehensive valuation report and selecting the appropriate conservator/restorer impacts greatly on the final outcome of valuation and/or re-introduction of a compromised work within the art market. To address these questions supported by case studies, SIA Fine and Decorative Art and Design MA director has invited Laura Doyle, vice-president, collections managers for Chubb Group of Insurance Companies, Sylvia Falcón, a specialist in the valuation of damaged works of art and artifacts with a long career in litigation support and experience as a government expert witness and Suzanne Siano, expert conservator of 20th century and contemporary easel paintings.

Debating Damage & Loss: Contemporary Paintings


One of the most challenging aspects of appraising a damaged artwork for the independent appraiser is establishing the loss of value without the benefit of another colleague to act as your sounding board. This session, part of a three-part series, will serve as an open forum for you to make sure you’ve covered all your bases when defending your argument for loss. Hosted by Jennifer Garland Ross, AAA, and Emily Thompson, AAA, each afternoon will focus on one specific period and medium, with a special guest appraiser working in that discipline. The group will meet at Modern Art Conservation, where Shauna Young, Senior Conservator, and the MAC team will demonstrate various treatments and conservation issues specific to contemporary paintings done in oil or acrylic on canvas. You will see some of the typical damages and hear the conservators' considerations and processes for conservation.

Hosted by Deborah Spanierman, AAA, Appraiser and past President of AAA.
