subjected to preliminary or fine size reduction. One way is to embrittle the sample in liquid nitrogen (N 2, LN) before grinding. At a temperature of -196°C even soft rubber becomes so hard and brittle that it can be ground without problems. Another possibility is to mix the sample with dry ice (CO 2). For indirect cooling, the grinding jar is
