Burmese teak is generally harder than rosewood. This conclusion is based on the Janka hardness test, which measures the resistance of wood to indentation. Burmese teak typically scores around 2,000 pounds per square inch (psi), while rosewood can range from 1,100 to 1,800 psi. The higher the Janka score, the harder the wood. This difference in hardness is due to the wood's cellular structure and density. Burmese teak has a denser grain and a higher wood density, making it more resistant to wear and tear. Additionally, rosewood is often used for decorative purposes due to its rich color and grain patterns, rather than its hardness.
