Seminar on cleaning acrylic emulsion paints

"Cleaning Acrylic Emulsion Paints"
A 2-Day seminar and workshop With

    Dr. Bronwyn Ormsby
    Senior Conservation Scientist
    Tate, London

Inp
150 avenue du President Wilson
93210 Saint Denis, France
15-16 May 2012

This workshop, presented by Dr. Bronwyn Ormsby, will inform
conservators about several important aspects relevant to the
conservation of emulsion (dispersion) painted works of art

Presentations will include an overview of artists' use, formulation
and chemistry of acrylic paints and a summary of the scientific
research carried out over the past few years into the effects of
conservation treatments. Research into novel and potential
wet-cleaning systems will also be presented and brought together for
evaluation in practical sessions across two afternoons.

In the practical sessions, conservators will evaluate the cleaning
efficacy of several established and novel cleaning systems on
provided artificially soiled samples and small sections taken from
test paintings. Participants will receive a bibliography, handouts
of the lectures, guides to practical tools, results tables and other
relevant information.

Participants are welcome to bring test samples of their own to use
during the afternoon practical sessions, however soiled samples will
be provided.

of Picture Conservator-Restorers (BAPCR) in October 2010, see The
