| Résumé : |
There is a continuing need to know whether a piece of finished leather is full grain or corrected grain, or has been printed. Microscopic examination of cross sections or cut edges, or of the surface of a piece of leather in question is not always helpful in detecting buffing of the grain or printing. It is difficult and time-consuming to extract reliable information on the condition of the grain surface from cross sections of the leather and, in any case, a cross section represents an extremely small sample of the surface under examination.
Because most finishes are applied with the aim of altering the appearance of the existing leather grain surface, examination of the finished surface under a stereo microscope or hand lens may not be informative. Satisfactory illumination is difficult because the uneven and often glossy surface of the finish produces reflections, shadows and glare which obscure important features. In some cases wehave found it virtually impossible to obtain information about the leather surface by using either light or scanning electron microscopy.
While considering the problems involved in deciding that treatments had been applied to the grain surface, we realized that more information would be obtained if a method of removing the finish were readily available. Many of the polymeric components of a finish are applied in organic solvents and most of them remainsoluble in these solvents. Thus we observed that application of one or more organic solvents to the leather finish usually removed enough of the finish to allow us to examine the underlying grain surface. |
