The scratch resistance of rock forming minerals is measured using Mohs hardness scale. This is a relative hardness scale ranging from 1 - 10 (with 1 being the softest e.g. Talc and 10 being the hardest - Diamond).A
Galena has a Mohs scale hardness of 2.5 - 2.75.B This is low by the standards of common rock forming minerals. As such it is unlikely that Galena will be capable of scratching the majority of other rocks or rock forming minerals.

Yes, galena has a hardness of 2.5 on the Mohs scale, meaning it can scratch rocks with a Mohs hardness of 2 or lower (such as gypsum or talc), but not harder rocks.

Which mineral scratches other rocks?
Diamond is the hardest mineral and is able to scratch other rocks.
Is galena a silicate?
Galena is a mineral, not a rock, but is commonly found emplaced in sedimentary rock from hydrothermal deposition in faults and fissures.
What kind of rocks can diamonds scratch?
Diamonds can scratch all types of rocks, as they are the hardest natural substance on Earth. This means that diamonds can scratch minerals like quartz, calcite, and feldspar, as well as softer rocks like limestone and shale.
What type of rock form is galena in?
First: Roast the Galena in a blast furnace for 30 minutes. Second: Add Carbon to the blast furnace to remove impurities. Third: Tag off your lead from the bottom of the blast furnace.
Does graphite scratch glass?
Yes, scientist have turned "mundane" form of carbon into diamond by applying enormous amounts of heat and pressure. These conditions are similar to what forms diamonds naturally. The process is expensive though.
Can a diamond scratch a rock or mineral?
Diamond will scratch all rocks and other minerals, including itself.
Which mineral scratches other rocks?
Diamond is the hardest mineral and is able to scratch other rocks.
Is galena a silicate?
Galena is a mineral, not a rock, but is commonly found emplaced in sedimentary rock from hydrothermal deposition in faults and fissures.
What rocks can scratch a diamonds?
Only a diamond can scratch another diamond due to its high hardness on the Mohs scale. Other rocks or minerals typically cannot scratch a diamond because they are not as hard.
Which mineral ranked the highest hardness?
A diamond is the hardest mineral. A diamond can scratch all other minerals or rocks and cannot be scratched by another mineral or rock except another diamond.
Can quartz scratch other rocks and minerals?
Yes, quartz is considered a hard mineral ranking 7 on the Mohs scale of hardness, making it able to scratch most other minerals. However, there are harder minerals such as diamond and corundum that can scratch quartz.
Can barite scratch other rocks or minerals?
Yes, barite is a relatively soft mineral with a Mohs hardness of 3-3.5, so it can be easily scratched by harder minerals. It is unlikely to scratch most common minerals or rocks, but can be scratched by harder minerals such as quartz or topaz.
What kind of rocks can diamonds scratch?
Diamonds can scratch all types of rocks, as they are the hardest natural substance on Earth. This means that diamonds can scratch minerals like quartz, calcite, and feldspar, as well as softer rocks like limestone and shale.
Can magnetite scratch other rocks and minerals?
Yes, magnetite is a hard mineral with a Mohs hardness of 5.5-6.5. It can scratch minerals with a lower hardness but can be scratched by harder minerals.
What does it mean when two rocks cannot scratch each other?
If two rocks cannot scratch each other, then they would have to be of equal hardness. A harder rock can always scratch a softer rock.
What type of rock form is galena in?
First: Roast the Galena in a blast furnace for 30 minutes. Second: Add Carbon to the blast furnace to remove impurities. Third: Tag off your lead from the bottom of the blast furnace.
