Preparation of ground sections using UV-curable acrylic adhesives

Study of ground sections is the most used and, in some respects, still irreplaceable method for examination microstructure paleontological and many other hard friable objects. At same time, samples are relatively difficult preparations high-quality thin sections. Many techniques means, particularly embedding media, have been proposed, but they often hardly accessible, imperfect or insufficiently studied. A promising easily accessible non-specialized medium, UV-curable acrylic adhesive (glue glass) was tested mounting objects with diverse mechanical optical properties. It shows notably good results, particular durability, reliable adhesion, ease use lack significant birefringence, which makes it especially valuable polarized light microscopy. Properties such adhesives reviewed compared properties epoxy resins a number media. Disadvantages ways to deal them also elucidated. In addition, broadly tools methods sawing, embedding, grinding, stages work discussed. Efficiency grinding agents measured. On basis all these technique making using means developed described step by step. The designed fossil bones, applicable dry samples, including paleontological, neontological geological ones.
