[QUOTE="Hawkear, post: 668847, member: 4728"] Ensure that the ”marks” are true scratch marks and not pressure marks. Things of the same hardness can still scratch each albeit quite weakly. They can more easily be made to mark each other if sufficient pressure is applied to cause the area of contact to be crushed. If a SG test can be performed that would add more info. [/QUOTE]
