What physical property of basalt (in this case diabase with alteration of 5-30% of its glassy matrix to clay mineral) is preventing simple hand-powered lapidary saws from cutting it effectively with quartz abrasive? And why flatten these blocks with percussion tools first in order to square them up which almost all of them have evidence of?
