Tutor(s): Richard Wolbers
This three-day workshop, organised in association with Trinity College Dublin and ICRI, the Institute of Conservator Restorers in Ireland, consists of morning lectures and afternoon practical sessions and is aimed at easel/panel paintings conservators and conservators of painted surfaces (e.g. furniture, etc) who are interested in new, less toxic, more effective, mainly aqueous methods for cleaning painted and coated surfaces.The importance of knowing the pH and conductivity of surfaces and solutions brought to such surfaces is discussed in detail in relation to building isotonic cleaning solutions and also the use of simple buffered and chelate-containing cleaning systems.
Simple aqueous gelling materials will be discussed together with surfactant chemistry and oxidation-reduction chemistry. The use of emulsions and micro-emulsions for blending solvent and water cleaning systems are discussed in relation to both traditional and contemporary artworks.
The aim of this workshop is to better inform participants about the formulation of tailored preparations for both surface cleaning problems (soil removal), and problems relating to varnish/coating and re-painting/over-painting removal.
This course is of most benefit to those with experience of paintings /objects conservation and a knowledge of conservation chemistry.
