Hans, I am a scientist with all the tools and instrumentation at my disposal to perform quantitative and qualitative chemical analysis - my vocation. I am also very conscious of statistical experimental design and the proof of the null hypothesis in testing and experimental work. I have analyzed the clear, colorless bore oil sold by several of the large instrument manufacturers and it is light mineral oil. Some go so far as to add volatile petroleum distillate fractions to speed evaporation giving the impression that the oil is readily absorbed into the wood. I have also analyzed the native Grenadilla oil extracted from the raw wood and the combination oil extracted from numbers of junk instruments from the major manufacturers and determined what they use to impregnate the wood. Commonly it is a plant derived oil. As I indicated, in accelerated studies (using increased, but not destructive, temperature to speed up chemical reactions - a common practice) I have documented, using phase contrast microscopy or other types of microscopy, denaturation of both the cellular structure and wood architecture of Grenadilla wood infused with mineral oil as well as other petroleum based products. Again, these studies demonstrate a process, not a chronology in everyday life which may take longer than you keep an instrument to be manifest.
