Arrised Edge
An arrised edge is a lightly processed glass edge where the sharp corners are removed.
The purpose is mainly to reduce sharpness and improve handling compared with a raw cut edge.
An arrised edge does not provide the same visual finish as a polished edge. It is more suitable for applications where the edge is not intended to be highly visible.
Typical considerations include:
- Reduced sharpness compared with a cut edge
- Basic edge treatment
- Suitable for hidden or less visible edges
Commonly used before further processing in some applications
Seamed Edge
A seamed edge is also a basic edge treatment.
The sharp edges are removed by light grinding or sanding, helping make the glass safer to handle during fabrication or installation.
Compared with a polished edge, the surface is rougher and more functional than decorative.
A seamed edge is often used where the glass edge will be covered by a frame, channel or other structure.
Ground Edge
A ground edge receives more processing than a simple seamed or arrised edge.
The edge is ground to create a more even and consistent finish, but it does not have the clear, glossy appearance of a polished edge.
This makes ground edges useful where a cleaner finish is required but a fully polished decorative edge is not necessary.
Flat Polished Edge
A flat polished edge is one of the most common decorative glass edge finishes.
The edge is ground flat and then polished to create a smooth, clear and finished appearance.
This type of edge is commonly used where the glass edge remains visible, such as:
- Glass shelves
- Table tops
- Shower glass
- Furniture glass
- Display glass
- Interior glass panels
The polished surface gives the edge a more refined appearance than arrised, seamed or ground finishes.
Pencil Polished Edge
Although not always grouped with the basic flat-edge types, pencil polished edges are also widely used in decorative glass applications.
Instead of a flat profile, the edge has a rounded shape.
This type of finish is often selected where a softer visual appearance is preferred.
For visible decorative glass, the choice between flat polished and pencil polished edges is usually based on the required design and application.
Main Differences Between Glass Edge Types
| Edge Type | Finish Level | Appearance | Typical Use |
|---|---|---|---|
| Arrised | Basic | Sharp corners removed | Hidden or less visible edges |
| Seamed | Basic | Rough, functional | Framed or concealed glass |
| Ground | Medium | Even but not glossy | Functional exposed edges |
| Flat Polished | High | Smooth and glossy | Visible decorative edges |
| Pencil Polished | High | Rounded and polished | Decorative glass applications |
The correct edge finish depends on how the glass will be used and whether the edge will remain visible after installation.
Which Glass Edge Should Buyers Specify?
When preparing a glass order, buyers should confirm whether the edge is:
- Visible or concealed
- Decorative or functional
- Installed in a frame
- Exposed to regular handling
- Part of furniture, shower, architectural or industrial glass
For custom processed glass, edge requirements should be included in drawings or specifications before production.
Using a clear edge description such as arrised edge, seamed edge, ground edge, flat polished edge or pencil polished edge helps reduce misunderstanding between buyers and glass processors.
Glass Edge Processing for Custom Projects
Different glass applications require different edge finishes.
MIGO provides glass processing solutions according to project requirements, including different edge finishing options for custom glass products.
For quotation, buyers can provide their glass type, dimensions, thickness, edge requirements, quantity, application and destination market.
If drawings are available, include the required edge details for technical review before production.
