Utilizing the Nanoparticles of Calcium Hydroxide and Magnesium Hydroxide for De-acidification of Dry Historic Wooden Objects: Immersion Method

Having a great eultural background and a splendid civilization., Iran has significant wooden objects among its so many valuable conservation objects. Wood is unstable substance, so it must be kept under conservational situations. Acidifying is one of common defects of wooden artifacts. Utilizing the nanoparticles of Calcium Hydroxide and Magnesium Hydroxide in relevance to Conservation basics and ethics, for managing an up to date efficient restoration method is the main goal of this research.Wooden samples taken from a historic piece of wood (dated about 10 A.H. /17A.C.) had a 3/98 pH. These uniform pieces were immersed in separate solutions of Calcium Hydroxide and Magnesium Hydroxide for an exact time under controlled situations. The results showed that nanoparticles of Magnesium Hydroxide are more efficient, because they have better identical penetration and adequate alkaline residue, and the cured wood can be more stable in future.
