This 3 day course to be held at the Army Museum, Stockholm consists of morning lectures and afternoon practical sessions which examine: basic aqueous cleaning techniques / strategies for textile substrates; the importance of knowing and controlling pH and conductivity of surfaces and solutions so that ‘isotonic’ bathing of fabric structures that are wet cleanable can be considered; and the use of simple buffered and chelate-containing bathing systems. Simple aqueous gelling materials for ‘spot’ treatments or stain removal will be discussed as well as surfactant chemistry and oxidation-reduction chemistry. The use and practical methods of making emulsions and micro-emulsions for blending solvent and water cleaning systems are examined in relation to both ‘wet’ and ‘dry’ cleaning needs – including the cleaning of water sensitive materials. Participants of this course will receive a copy of the book ‘Gels in the Conservation of Art’ (Proceedings of the 2017 London conference).
