The restorer activity that Manetti & Masini started in 1948, allowed the craftsmen to "copy" the most beautiful objects they had in restauration.
Through the observation of the broken pieces they could study the composition of these objects of art, in particular: materials (for example terracotta, pottery), glazes, decorations, patinas, paints and so on.
They finally could realize very beautiful copies, similar to the original ones in all the details.
