Calcium alkoxides for the conservation of stone and woodhistorical artifacts
Despite the great number of treatments that have been used and are still in use to cope the problem of deterioration of lime-based historical artifacts, no real solution has been found yet. Neither the organic polymers nor inorganic treatments have demonstrated to guarantee satisfying performances. If the former suffer from incompatibility with the substrate and long-term irreversibility (due to physico-chemical modification of the polymer itself), the latter, though more compatible, show the drawback of scarce solubility. To overcome this problem, micro-and nano-dispersions of calcium hydroxide in alcohol have recently also been prepared and tested.
