There are some archaeological bones resulting from some 
archaeological excavations, and they have many different 
manifestations of damage such as brittleness, fragility and weakness, 
and through the aging of some samples that have been strengthened 
with In this study, nano-hydroxyapatite concentrations of 1% and 2% 
+ nano-paraloid concentration of 3% dissolved in acetone as an 
archaeological bone-strengthening substance . Visual assessment and 
several analytical techniques were used for the evaluation of the 
selected strengthening material . The analytical techniques are 
transmission electron microscope (TEM), color change and Pressure
strength. The results obtained from transmission electron microscope 
showed that grain size of nano-hydroxyapatite with nano paraloid 
was ranging from 51 to 73 nm .
