Feasibility of handmade varnish colours for chromatic reintegration through experimentation
Keywords:

This article investigates the feasibility of self-manufacturing non-aqueous paints for chromatic reintegration. This artisanal practice, historically carried out by artists and increasingly adopted by restorers, responds both to problems of stability, finish and conservation of specialised commercial paints, and to the need to reduce costs in restoration processes. Taking into account the apparent advantages of handmade colours, an experimental study has been carried out through the elaboration and analysis of laboratory tests with different combinations of pigments and varnishes. Through accelerated ageing tests, microscopic observation and colorimetric analysis, the cohesion, homogeneity and stability of the mixtures have been evaluated. The results indicate that the viability of this practice depends largely on the nature of the materials and their correct formulation, concluding that, under certain conditions, they could be considered for applications in professional restoration contexts with the possibility of optimizing their properties.
