In the summer of 2010 I was asked to restore the family grave at Bolzano.
It is composed by a block of reddish limestone with a flute-playing angel on the top. To the right and to the left there are two more blocks with the names of the deceased engraved. Due to the infiltrating water the stone was bursting in some places. With the cold the water freezes and expands. We also found a collection of ivy and moss, the surrounding plants grew in the stone and let him split. The angel’s fingers were missing, parts of the holy certificate and the tip of the flute was also lost. The inscriptions were no longer legible. As a first step a dry cleaning was performed to remove the superficial dirt. There was a second cleaning with ammonium salts with a pH value of 8.5, carried out with a brush and the scalpel. After that the whole stone parts were rinsed with water and the dirt washed off. The cracks were closed with a stucco made of marble powder, limestone, sand and Peoval; also the false have been replaced. The said bodies have been inked and adapted to the tone of the stone. The font was retouched with acrylic colors on water base. As a final step a protective layer was applied.
