# The Mortars of Florence Riverbanks: Raw Materials and Technologies of _Lungarni_ Historical Masonry
## 3 Macroscopic Description
The study of the masonry carried out through macroscopic description, identification of the mortar types and their distribution in the core samples in the masonry, allows identification of the most representative portion for the characterization of masonry cores. The representative samples of the various mortar types present in the core samples were selected for comprehensive diagnostic investigation. \begin{table}
