How does granite’s hardness affect tool wear during sculpting?
Granite, known for its exceptional hardness and durability, poses significant challenges for sculptors due to accelerated tool wear. With a Mohs hardness rating of 6-7, granite demands specialized tools—typically diamond-tipped or carbide—to withstand abrasion. The harder the granite, the faster conventional steel tools degrade, leading to frequent sharpening or replacement. Diamond tools, though costly, offer superior resistance, reducing wear and improving precision. Factors like quartz content further influence wear rates, making tool selection critical. Proper cooling techniques and slower cutting speeds can also extend tool life, ensuring efficient and cost-effective granite sculpting.
