History and Use of Medieval Pigments
A Workshop by Cheryl Porter
At the New York Academy of Medicine
1216 Fifth Avenue
New York,NY 10029
May 13-17, 2002
9 am - 5pm

The New York Chapter of the Guild of Book Workers will host a
five-day workshop on the History and Use of Medieval Pigments and
Inks. The morning sessions will include discussions of original
recipes, methods of manufacture, trade routes, cost, and
iconographic importance. Chemical and physical properties of
pigments and media will also be addressed. Pigments including earth
colors, medieval blues, gold and verdigris; inks including iron
gall, sepia, carbon blacks; media including gum and egg; and dyes
and lakes will be examined. Various methods of identifying pigments
will be discussed. The afternoon laboratory sessions will include
preparation of samples of the colorants discussed in the mornings,
as well as the painting of samples to produce a pigment chart.
Appropriate methods for taking samples from original manuscripts
will be demonstrated. Practical methods for consolidating flaking
and friable pigments will be discussed and demonstrated. The
coloring of alum tawed animal skins used for conservation work will
also be given practical consideration.

The workshop will be presented by Cheryl Porter. Ms Porter,
following her conservation studies at Camberwell College of Arts in
London, worked at University College London in the Painting Analysis
Unit and in the History of Art Department analyzing pigments and
application techniques used to illuminate medieval manuscripts. She
has worked closely with the University of Cambridge on the analysis
and conservation of pigments and dyes. Ms Porter lectures and
teaches throughout the UK, Europe, and Australia and has been
director of the Montefiascone Library Conservation Project in Italy
since its inception in 1988.

Cost: Morning lecture series only: $40 NYC/GBW members, $60
non-members.  Places are still available.
