收藏: Leather Polishing Discs

Leather polishing discs are a time-tested polishing surface for achieving a mirror-bright final polish on lapidary cabochons and hard stones. The firm, slightly textured leather surface holds diamond compound paste and cerium oxide evenly, delivering a controlled, high-gloss finish on agate, jasper, quartz, obsidian, and virtually all hard polishable stones. Preferred by experienced lapidary artists for the tactile feedback and consistent results leather provides over softer polishing surfaces.

Frequently Asked Questions

• Q: What polishing compound should I use with leather polishing discs?
  A: Diamond compound paste (14,000-100,000 grit) is the most effective compound for leather polishing discs on hard stones like agate, jasper, and quartz. Cerium oxide works well for glass and softer stones. Apply a thin, even coat - a little compound goes a long way on leather.
• Q: Why do lapidary artists prefer leather polishing discs over felt or canvas?
  A: Leather provides a firmer, more controlled polishing surface than felt, giving experienced lapidary artists better tactile feedback and more consistent results on hard stones. The slight texture of leather also holds compound more evenly than smooth surfaces.
• Q: How do I break in a new leather polishing disc?
  A: Apply a small amount of diamond compound to the leather surface and work it in with a hard plastic or wood burnishing tool before first use. Run the lap at low speed for a few minutes with light stone contact to condition the leather surface before polishing at full pressure.
• Q: Can leather polishing discs be used wet?
  A: Leather polishing discs are typically used dry or with a minimal amount of compound carrier. Avoid flooding with water - excess moisture softens the leather and reduces polishing effectiveness.
