Instructors
Rene de la Rie (University of Amsterdam & CRCC,
Paris) received M.S. and Ph.D. degrees in
chemistry from the University of Amsterdam (UvA),
The Netherlands. He is currently chercheur
associee at the Centre de Recherche sur la
Conservation des Collections (CRCC/CNRS), Paris
and a guest researcher at the UvA. He was head of
the scientific research department at the National
Gallery of Art, Washington, DC from 1989 until
2012, a position endowed by the Andrew W. Mellon
Foundation. He has also held positions at the
Metropolitan Museum of Art, New York, and at the
Training Program for Conservators (now UvA) and
the Central Research Laboratory for Objects of Art
and Science (later ICN, now RCE), both in
Amsterdam. He has been an adjunct professor at the
University of New York and the UvA and served as
Ph.D. advisor at the latter institution. He was an
editor for the journal Studies in Conservation on
from 1994 un l 2011 and has published extensively.
Jill Whitten and Robert Proctor have been in
private practice in Houston, Texas since 1998.
They work on private and institutional collections.
Jill Whitten received a Bachelor of Fine Arts in
Studio Art at the University of Texas, Austin. She
studied conservation at Buffalo State College,
where she received a Master of Arts and a
Certificate in Conservation. She has worked as a
conservator and undertaken resin research at the
Art Institute of Chicago, J. Paul Getty Museum and
the National Gallery of Art. She treated a
collection of paintings by Frederic Remington at
the Museum of Fine Arts, Houston. Since 1993 she
has been lecturing and teaching workshops on
resins for varnishing and retouching in North and
South America and Europe.
Robert Proctor has a Bachelor of Arts in Art
History from Tulane University in New Orleans and
a Master of Arts and Certificate of Conservation
from Buffalo State College. He trained in Munich
at the Bayerisches Nationalmuseum, worked at the
Saint Louis Art Museum, Indianapolis Museum of Art
and Museum of Fine Arts, Houston. In addition to
workshops on varnishes, Rob is a specialist in the
reweaving of tears and has taught workshops on
reweaving. He has worked as a contract conservator
and treated a number of public murals.
Overview
Many different materials have been used for
varnishing and retouching. Traditionally, natural
resins were primarily used for this purpose. In
the 20th century synthetic polymers were
introduced. These are often chemically and
physically more stable than their natural
counterparts. The optical properties of varnishes
are however largely controlled by their molecular
weight. By using synthetic low molecular weight
resins for varnishing and retouching, an
appearance similar to that obtained using natural
resins can be achieved. Factors affecting
stability and appearance, as well as application
methods and solvents suitable for these new
resins, will be discussed.
The workshop will focus on synthetic low molecular
weight resins and how they differ from polymers
and dammar. Participants will use practical
sessions to evaluate the properties of resins used
as varnishes in terms of their application and
appearance. Through these practical sessions and
demonstrations, participants will establish how
the choice of resin, solvent or stabiliser will
affect the properties of the varnish not only on
application but subsequently upon ageing.
Participants will leave the master class with an
individual canvas board (60x80cm) on which at
least 15 varnish recipes have been tested.
Lectures will cover:
- Function of varnishes
- Chemical properties of resins and their degradation
- Factors affecting optical characteristics of
varnishes
- Effects of stabilisers
- Retouching media
- Criteria for choosing appropriate varnishes
- Varnish application techniques
- Solvent selection: polarity, solvent strength
and evaporation rates
Materials:
Varnishes and artist canvas boards will be
provided. Participants are encouraged to bring
their favourite brush for applying varnish.
