Dima for Masegno
Dima is a wodden device created by Insula in order to measure the proportionality of Pavement stones. Every Stone is measured before it is used in any pavement project, this ensures that all stones used in the street pavements will fit in with the unique look and style of Venetian pavement. This device was created after various incidents where disproportional and irregularly shaped stones were used by workers to replace sections of pavement, this made the street look out of place and not consistent with other Venetian streets.[1]
Size Specifications
The tool was designed so that the minimum surface area is 12 cm^2 for any new masegno used, and 6 cm^2 for any old (recycled) masegno used. The shortest side has to be at least 20cm for any stone used, and the height of the stone has to be greater than 5/4 but smaller than 11/4 the width.[2]
Measuring a Stone
There are two variations of the dima, one for old masegno and one for new masegno. The two variations are identical, except the size of the window for new stones is smaller than the size of the window for old stones. This is because the minimum allowable surface area for old stones is half as large as the minimum allowable surface area for new stones. The tool is very simple to use. First the corner of the stone is lined up with the corner of the dima, if the diagonally opposite corner of the stone is visible through the cut out window, then the stone is ok to use. If any stone does not appear in the cut out window, or is larger than the dima it is not ok to use.[3]
