Abstract
This paper deals with an innovative technique regarding the embedding of biliary stones in plastic materials as an alternative and viable solution for increasing their mechanical resistance during processing for preparing the samples for instrumental analysis. The human gallstones provided from a single patient were embedded in two different polymeric plastics. The samples were investigated for their mechanical resistance under surface grinding using a rotating abrasive wheel on a bench grinder, as well lathing on a lathe machine. A discussion for the best method of embedding and the sample preparation is presented.
