Unpolishable

The adjective 'unpolishable' describes a substance or surface that cannot be made smooth, shiny, or refined through the process of polishing. This might be due to its inherent material properties, such as a rough, porous, or abrasive texture, or because it is coated in a material that prevents the polishing process from taking effect. The unpolishable nature suggests a permanent state of a rough or unfinished condition, resistant to improvement by conventional polishing methods.

Unpolishable meaning with examples

• The rough, volcanic rock was completely unpolishable. No matter how long the artisan worked on it, the surface stubbornly retained its coarse, jagged texture. The stone's imperfections, though beautiful, were beyond the reach of any polishing equipment, showcasing its natural ruggedness, its very essence defiant to refinement.
• Despite several attempts with various abrasive compounds, the antique iron gate remained stubbornly unpolishable. Rust and pitting, combined with its inherent rugged cast-iron surface, resisted any efforts. It retained its aged, time-worn character, reflecting decades of weather and use, and its patina instead enhanced the rustic appeal.
• The composite material used in the construction of the new spacecraft's hull was deliberately designed to be unpolishable. Engineers sought a surface texture that optimized heat dissipation during reentry. Any attempt to polish it would have rendered its advanced properties useless, making the material suitable for space travel.
• The sculptor’s choice to leave the marble intentionally unpolishable underscored his artistic vision. By embracing the stone’s inherent texture and imperfections, he created a piece full of authenticity. The raw and unrefined feel of the material gave the work a unique tactile quality, rejecting the usual polished aesthetic.
