Polishing and buffing metal
Polishing is the final step that gives a jewel its shine. It consists of removing marks with ever finer abrasives until the surface reflects like a mirror.
From sanding to shine #
- File and sand (grit 400, 600, 800, 1200).
- Polish with a cotton or felt wheel and a cutting compound (tripoli, brown).
- Buff with another wheel and a fine compound (rouge, red).
Tools #
Flex shaft or bench polisher with felt, cotton and bristle wheels and points; polishing compounds. One wheel per compound, so they do not mix.
Safety #
Tie back hair and avoid loose clothing; do not wrap the piece or hold it with the wheel toward you; wear glasses and a dust mask.
What to polish and what not #
Soft stones and enamels are not polished on the wheel. Repeated polishing removes metal: do not do it more than necessary.
Step by step #
- File and sand. Up to grit 800 or 1200.
- Choose the wheel. Felt, cotton or brush.
- Tripoli. Wheel with cutting compound (brown).
- Clean. Wash the piece to remove the compound.
- Rouge. Another wheel with fine compound (red).
- Wash. Ultrasonic or soap, and dry.
Tools and materials #
- Flex shaft or bench polisher

Common mistakes #
- Mixing compounds on one wheel.
