- Abstract
It is believed that old and used musical instruments have better accoustic than new fabricated ones. The nature of the type of varnish used on musical instruments it's a subject that has been debated for a long time. The main purpose of the paper is to analyze the effect of artificial aging on the color parameters of the varnish film used in violin varnishing. Thus, samples of resonance spruce wood from different classes of anatomical quality were studied, some covered with alcoholic varnish and others with oil-based varnish, in 5, 10, 15 layers. The color parameters were measured with a Konica Minolta colorimeter device, measurements being taken on the lacquered surface in 3 points, both before and during exposure to UV radiation for 1000 hours. The results highlighted the fact that the lightness and the redness are the parameters most affected by the effect of photo-degradation. The anatomical structure of the spruce wood (class A and D) is another factor that influences the intensity of the color changes of the varnish film. The anatomical structure of the spruce wood (class A and D) is another factor that influences the intensity of the color changes of the varnish film. In general, all color parameters have lower values on class D spruce wood (with wide annual rings), compared to class A wood (with narrow annual rings) whose color parameters are up to 7 - 10% higher.
