Abstract

Archaeological bones are exposed to many different factors of damage as a 
result of some natural weathering in the burial environment. The aim of this 
research is to identify the most important physical, mechanical and chemical 
problems of such bone and to present one of the new solutions to improve 
its properties by using Nano applications represented in the use of Nano –
paraloid dissolved in acetone at a concentration of 3 % as one of the 
proposed strengthening methods, Visual assessment and several analytical 
techniques were used for the evaluation of the selected Strengthening. The 
analytical techniques are transmission electron microscope (TEM), FourierTransform infrared Spectroscopy (FTIR), Measurement of Mechanical 
Properties (pressure strength) , and Measurement of physical 
Properties(Color Change CIE Lab, Density, Porosity and Water Absorption) , 
The bone samples were subjected to accelerated aging (thermal - chemical) 
after applying the stiffener, The results obtained from transmission electron 
microscopy showed that the size of nanoparticles of paraloid was between 58 
and 78 nanometers. The results of measuring the pressure strength of the 
reinforced samples and comparing them with the standard sample (ST) 
(70.86 kg/cm2), where the reinforcement sample of nano-paraloid recorded 
(NP), the highest measurement (258.93 kg / cm2). Color change revealed 
gave the higher level of total color differences (ΔE), the (NP) sample was 
(16.45) .
