Frequently Asked Questions
-
Q: What is the difference between a zinc lap and a tin lap?
A: Zinc laps are softer and work well for pre-polish and polish stages on hard stones like quartz and agate, typically charged with diamond compound or cerium oxide. Tin laps are harder and produce a higher-gloss finish, making them preferred for faceting sapphire, ruby, and other corundum-group minerals. -
Q: Which polishing compound should I use with a copper lap?
A: Copper laps are best charged with diamond paste (0.5–3 micron) for pre-polish and polish on hard gemstones. Their dense surface retains diamond compound effectively for consistent, repeatable results. -
Q: Can I use a leather lap for hard stones like sapphire?
A: Leather laps are generally recommended for soft to medium hardness stones (Mohs 5–7), such as opal, turquoise, and feldspar. For hard stones like sapphire or ruby, tin or zinc laps with diamond compound are more effective. -
Q: What is the difference between a flat lap disc and a polishing lap?
A: Flat lap discs are typically used for grinding and shaping cabochons on a flat lap machine, while polishing laps are used in the final stages to achieve a mirror finish. Many flat lap machines accept interchangeable laps for both grinding and polishing. -
Q: When should I use a sintered faceting lap versus a standard faceting lap?
A: Sintered faceting laps have diamond particles embedded throughout the metal matrix, offering longer life and consistent cutting on very hard stones (Mohs 8+). Standard faceting laps are surface-coated and are well-suited for softer to medium-hard stones and general faceting work.
