Kolekcja: Zinc Polishing Pad

Solid Zinc Polishing Lap has been a cornerstone in professional gem cutting, prized for its durability, rigidity, and ability to deliver high-quality polish on gemstones ranging from the hardest corundum to softer materials. Unlike Tin Laps, Zinc Laps excel in creating flat facets efficiently, even on challenging stones like cubic zirconia.

Key Advantages of Solid Zinc Polishing Laps

1. Material & Construction

   • Made from full-thickness zinc alloy, these laps eliminate the need for a Master Lap base or backing plate.

   • Re-machinable for extended usability, ensuring long-term value for professionals.

2. Performance

   • Ideal for hard gemstones like sapphires, rubies, and cubic zirconia.

   • Delivers a high-gloss finish across a wide hardness spectrum.

3. Versatility

   • Compatible with polishing powders and diamond compounds for tailored results.

Step-by-Step Preparation Guide

1. Surface Conditioning

   • Begin with 60-80# sandpaper to remove scratches, working from the outer edge inward.

   • Repeat with 240# sandpaper for a smoother base.

2. Polishing Paste Application

   • Mix polishing powder with diamond oil to create a paste.

   • Apply evenly and polish using 50-150# sandpaper.

3. Humidity Control

   • Maintain slight moisture on the lap surface to optimize polishing efficiency.

   • Continue until the surface darkens, indicating readiness for gemstone work.
