Abstract

The research dealt with one of the modern applications of restoring and conserving antiquities. One of the most important applications is the use of nanoparticles and their addition to traditional consolidation materials to improve their properties in consolidating glazed pottery samples. This paper aims to evaluate the use of wacker OH100 in its traditional form and wacker OH100 + nano silver to improve its properties and apply it to the experimental glazed pottery samples. This study used some investigation and analysis methods for the evaluation process. TEM was used to measure the size of prepared nanocomposites. Microscopes such as SEM and USB digital were used to investigate the surface morphology. Static water contact angles were measured to assess the hydrophobic characteristics of the consolidants utilized in this investigation. Color change, as well as physical and mechanical testing, were all examined. According to the findings of this investigation, the treated sample with Wacker OH100 + nano Silver at 3% achieved the best results where contact angle reached to 116o, colour change stops at ∆E value 5.43 and compressive strength reached to 518 Kg/cm2 with improvement rate 64.96%.
