The Covington Felt Polishing Dome is designed for polishing the inside lips and curved interior surfaces of glassware and bottles. Its rounded felt surface conforms to curved areas that flat polishing discs can't reach. Use with cerium oxide to achieve a smooth, optically clear finish. Includes a 5/8"-11 threaded brass adapter for compatible Covington equipment.
Polish curved glass surfaces and inside bottle openings with the Covington Felt Polishing Dome, a specialized accessory designed for use with Covington Flat Lap and Beveler/Grinder machines.
The large felt dome conforms to curved interior surfaces, making it especially useful for polishing the inside lip and opening of glassware, bottles, and other curved glass surfaces where a traditional flat polishing disc cannot reach.
When used with cerium oxide, the felt surface produces a smooth, high-quality finish and can bring glass to an optically clear polish. Covington includes a 5/8"-11 threaded brass adapter, allowing the dome to attach directly to compatible Covington equipment.
Designed for Polishing Inside Curves
Flat polishing discs are excellent for working flat surfaces, but curved interiors require a different approach. The Covington Felt Dome provides a broad, rounded polishing surface that follows the contour of the glass.
It is particularly useful for:
- Polishing the inside lip of glass bottles
- Finishing curved interior glass surfaces
- Polishing glassware and decorative glass
- Refining surfaces after diamond grinding
- Achieving an optically clear finish on glass
- Working areas that are difficult to reach with a flat polishing disc
Use with Cerium Oxide for a Brilliant Finish
For glass polishing, pair the Felt Dome with cerium oxide polishing compound. The combination of the soft felt surface and cerium oxide is designed to produce a smooth, clear finish on properly prepared glass.
For the best results, the glass should already be fully ground and smoothed before beginning the final polishing stage. The Felt Dome is a polishing accessory, not a grinding tool, so it should be used after the surface has been brought to the appropriate pre-polish condition.
Made for Covington Flat Lap Equipment
The Felt Dome includes a 5/8"-11 threaded brass adapter for attachment to compatible Covington Flat Lap equipment. The threaded connection makes it easy to install the dome when you need to switch from flat-surface polishing to interior or curved-surface work.
Covington also offers diamond cones and domes for grinding and smoothing inside curves, making the Felt Dome a natural final-polishing accessory for a complete bottle and glass-working setup.

Large polishing surface: At approximately 4-1/2" across the base, the dome provides substantial contact area for efficient polishing.
Ideal for glass: Designed specifically for glass polishing and particularly well suited to inside bottle lips and curved glass surfaces.
Professional-quality results: Used with cerium oxide, the Felt Dome can produce the optically clear finish expected from professional glass polishing.
Easy installation: The included 5/8"-11 brass adapter makes the dome ready to attach to compatible Covington equipment.
Complete Your Glass-Polishing Setup
For a complete bottle and glass-polishing workflow, use diamond grinding and smoothing accessories to prepare the surface before switching to the Felt Dome for final polishing. Covington's Bottle Kit, for example, pairs a fine diamond cone with a felt polishing cone, diamond grinding discs, a felt polishing disc, and optical-grade cerium oxide.
Covington Felt Polishing Dome — a specialized finishing tool for bringing curved glass surfaces to a brilliant, optically clear polish.
