Glass

*1: We precrushed the glasses with a hammer in a plastic bag to a fineness of 15mm.
*2: The sample starts to stick(see attached picture).Another dry grinding is not possible.
*3: See particle size on our laser-particle-sizer ANALYSETTE 22-NanoTec, measuring-no. 6687. The achieved particle size(d50<12,6µm) of dry grinding, you can take out from measuring no. 6685.

First, we dry grinded the sample for 5min, till it started sticking(see 1a). Then we put 15ml water in the bowl and grinded another 10min.
