Effects of various treatment methods on decay resistance and dimensional stability of nano-silver-treated Persian/Shiraz inlay (Khatam)

Four types of Shiraz inlay (Khatam) samples were impregnated with nano-silver solution via spraying (S), a vacuum desiccator (VD), and immersion/dipping (I/D) for 2 h 24 techniques. The decay resistance dimensional stability evaluated after each treatment. specimens exposed to white-rot fungus 10 weeks by the agar-plate method, weight loss was determined assess decay. soaking in water measured. According results, highest (13.1%) observed Shesh-Pareh Khatam (SPK)-untreated lowest (1.5%) occurred Ostokhani (OK)-VD-treated samples. volumetric shrinkage (39.0%) Haft Shamseh Alam-Zar (HSAZK)-untreated soaking, (3.8%) noted OK-S-treated soaking. swelling (64.1%) HSAZK-untreated (4%) found water. Generally, anti-shrinkage-efficiency (111.0%) anti-swelling-efficiency (145.4%) SPK-VD-treated samples, respectively.
