There are many minerals with hardness above 5.5 but the standard ones are feldspar,quartz, topaz, corundum and diamond.
A few minerals that do not scratch glass come to mind . . . talc, asbestos, mica, for instance.
Any mineral with roughly a hardness of 6 or more on the Mohs scale of mineral hardness could scratch glass, which is roughly 5.5 on the Mohs scale. Some minerals that could scratch glass would be quartz, topaz, corundum, and diamond.
