A straightforward and low‐cost method for the preparation of low‐melting‐point powder samples is presented. This simple technique, suitable for materials that are liquid at ambient temperature, involves freezing and subsequent hand‐grinding of the material using a chilled stainless‐steel mortar, and has enabled high‐quality powder samples to be produced from compounds with melting points down to 167 K. By this method, a number of samples have been successfully prepared for detailed structural studies using high‐resolution neutron powder diffraction. A recent example of the study of toluene, melting point 177 K, is given.
