The influence of vanishing process on the vibrational properties of the wood+coating systems was studied using different types and recipes of instrument making varnishes, used in traditional Iranian string instruments making, or in European violin-quartet making. The focus is on the time evolution of these properties, that can be involved in the changing behaviour of newly made instruments. The different tested varnishes recipes were applied on wood representative of each culture, studied both along-the-grain and cross-grain, and monitored through time for up to more than one year. The different effects, both immediate and their kinetics through time after application, are discussed.
