Part II: July 2021 (6 CFU : 150 hours)

. Introduction to the diagnostic investigation activities, in coordination with the scientific
Laboratories. UV ; IR ; photo shooting sessions ; XRF ; microchemical analyses addressed to the
analysis of constituent materials and products of alteration.

. General theoretical introduction and practical applications to the phases of:

a) Preliminary biocide treatment

b) Re-establishment of adhesion and cohesion of pictorial film and preparatory layers
. infiltration of acrylic microemulsions
. achievement of planarity through controlled thermal spatula

c) 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,

d) fillings of gaps (lacuna)
. application and texture

(e) Aesthetic presentation
. theoretical principles of pictorial reintegration with topic of history of restoration
. Lacuna and theory of visual perception (Gestalt psychologies),
. reintegrable lacuna and non-reintegrable lacuna: tratteggio technique and sublevel.
. reintegrative treatments in comparison: lowering of tone with ‘dirty-water’ technique and
mimetic intervention

(f) Intermediate and final varnishing.

The lab activities will be organized under the constant supervision of the professor. Any material used in the practice of the intervention will be introduced in total safety through the awareness of technical sheet.
