Frequently Asked Questions
-
Q: What polishing compound works best with felt burs for gemstone polishing?
A: For hard gemstones (Mohs 6+) such as agate, quartz, and sapphire, use diamond compound paste (8,000–50,000 grit) on felt burs for a mirror finish. For glass and light-colored softer gems (Mohs 5–7), cerium oxide produces an excellent optical-quality finish. For soft stones like turquoise, opal, and malachite, tin oxide provides a gentle final polish without over-cutting the surface. -
Q: What rotary tool speed should I use with felt polishing burs?
A: Use medium speed (5,000–10,000 RPM) with light, consistent pressure. High speeds generate heat that can damage delicate gemstones and burn the felt. Keep the bur moving continuously to avoid flat spots and uneven polish. Apply a small amount of compound to the bur and work in small circular motions. -
Q: Can felt burs reach inside carved recesses and detailed areas?
A: Yes — felt burs are specifically designed for detail polishing in areas that flat pads and wheels cannot reach. Different tip shapes (ball, cylinder, cone, flame) allow access to different surface profiles. Ball-tip burs suit concave recesses; cylinder burs suit flat-bottomed channels; cone burs suit V-grooves and pointed recesses. -
Q: Do felt polishing burs work on glass?
A: Yes — felt burs with cerium oxide are excellent for polishing carved or engraved glass surfaces. The soft felt conforms to the glass surface and the cerium oxide produces an optical-quality finish. Use light pressure and medium speed to avoid heat buildup on glass.
