For the test series, Krogmann and his colleagues prepared fossil sea urchins using different methods and then compared the resulting surfaces under a scanning electron microscope. The microstructures were best revealed when a chemical method was used. The application of sodium hexametaphosphate (NaPO3)6 produced significantly better results than the classical preparation with lime potash, acetic acid and the sandblast preparation. “So this method is an important improvement,” says Martin Krogmann. His primary concern is to develop a method for microfossil preparation that is as non-destructive as possible.
A commission decides every three years who will win the René Lanooy sponsorship award. The prize is endowed with 3000 Euros and is given for special preparations and new methods in the areas of medicine, biology and geosciences.
