Workshop on Modular Cleaning Program

From: Masse Emilie <emilie.masse<-at->
Date: Wednesday, May 22, 2013
Modular Cleaning Program Workshop: Aqueous Cleaning
Institut national du patrimoine
Departement des restaurateurs
150 avenue du President Wilson
93210 Saint-Denis La Plaine
July 10-12 2013

Formation Permanente de L'institut National du Patrimoine

Speaker:  Chris Stavroudis, paintings conservator, Hollywood.

Coordinator: Laetitia Desvois, paintings conservator
Translator (English/French): Anne Baxter, paintings conservator

Goals/ Scope: By taking this course conservators will gain a solid
foundation in the theory and practice of formulating aqueous
cleaning solutions and polymer-stabilized emulsions. Participants
will receive information on cleaning through lectures and readings.
They will also learn how the Modular Cleaning Program stock
solutions and computer database assist in formulating effective
cleaning strategies.

During lab time participants will prepare the stock solutions,
become proficient with the MCP computer database and learn to use
the MCP to fine tune the cleaning of test paintings. After preparing
the stock solutions, conservators will prepare a series of aqueous
test solutions to arrive at an optimal cleaning system for a test
painting (as each painting is different). Of critical importance,
the participants will learn about clearance of non-volatile
materials and the advantages and disadvantages of using cleaning
systems that contain components that do not evaporate.

The aim of the workshop is to provide the participant with the tools
to use the Modular Cleaning Program in their own practice as soon as
they return to their own studios. After the workshop, participants
should be comfortable mixing the solutions, working through aqueous
test cleanings, and understand how various changes in materials will
affect the cleaning solution and how this relates to the chemistry
of the surface and cleaning system. Participants will leave the
course with a set of the stock solutions that will include bottles
of aqueous concentrate solutions and rinsing solutions.

Intended participants:  conservators of polychrome art pieces

Price:  795 Euro
