. General theoretical introduction and practical applications to the phases of:
a) Surface cleaning:
. critical principles: the dialectic between original, patina and overpainted layers
. orientation on parameters of toxicity,
. solvents (evaporation, penetration, solvent power), solvent parameters,
solvent triangle, solubility testing, solubility
. concept of polar/apolar,
. acids and bases,
. tensioactive and chelates,
. watery environment,
. thickening solutions, gels
b) fillings of gaps (lacuna)
