A mixture of lime, riversand and
finely ground marble powder is uniformly
spread over a wooden tablet in diverse layers. The layers are applied in various
thicknesses for better adhesion.
The final layer gives a "wall" effect
whose eventual thickness is determined
according to the original work from which the detail was drawn.
The image is then painted onto the prepared base using
pulverized colours that
have been amalgamated with traditional liquid adhesive compounds.
Once the base colors have been laid down, the painting is
finished using a series
of "velatura", ensuring the same grade and quality of highlights and opacity as
the original work.
