Based on Moh's Scale of Hardness that identifies minerals, it is. Moh's Scale of Hardness
Quartz is harder than copper. We did a lab at school
yes quartz is harder than copper.
Yes, much harder.
If you mean isn't harder than quartz but harder than apatite ( you spelled it wrong), that would be Orthoclase Feldspar. Else the minerals that are harder than both apatite and quartz are topaz, corundum, and diamond (diamond being the hardest, well the hardest non synthetic mineral).
Topaz is very much like quartz. They both can be found naturally in any color. They're both harder than glass. Topaz is, however, a little bit harder than quartz and will scratch quartz.
Quartz because it is harder, more durable and more resistant to scratching than calcite.
Quartz- hardness 7 on Mohs Scale. (Calcite: 3, galena 2.5, talc 1)
Quartz is harder than apatite, quartz being a 7 on the Mohs mineral hardness scale and apatite being a 5.
Why is quartz harder steel
Yes an emerald or green beryl is harder than quartz

Quartz because its harder than calcite and the quartz in thicker.
Mohs measures relative hardness (quartz is harder than orthoclase; topaz is harder than quartz), but it doesn't accurately tell HOW MUCH harder something is than something else. There is another scale, called the Rockwell, which does this.
because nickel are stronger and harder than copper, also has more resist to corrosive.
Brass is harder because it is an alloy of copper with tin.
Quartz because it is harder, more durable and more resistant to scratching than calcite.
Answer: The new smelting processes made them stronger -Apex
yes
