Polished, Bevelled or Arrised? Mirror Edge Finishes Explained

When investing in a bespoke mirror, the details truly make all the difference. Beyond the size and shape, the often-overlooked edge finish plays a significant role in the mirror's overall aesthetic, its safety, and how it integrates into your space. Understanding the nuances between polished, bevelled, and arrised edges is key to achieving a sophisticated and functional result.

This comprehensive guide from Glass Tailors will demystify mirror edge finishes, providing you with the knowledge to choose the perfect option for your next project, whether it's a grand hallway mirror or a subtle bathroom addition.

Key Takeaways

• Arrised Edges are the most basic and safest finish, ideal for mirrors that will be framed or recessed.
• Polished Edges offer a smooth, shiny, and refined look, perfect for exposed mirror edges in modern designs.
• Bevelled Edges provide a decorative, angled facet that adds depth and a touch of classic elegance.
• The choice of Edge Finish impacts both the visual appeal and the practical safety of your bespoke mirror.
• Consider the mirror's location, style, and how it will be installed when selecting your preferred edge.

Understanding Mirror Edge Finishes

The edge of a mirror, though seemingly minor, is a critical design element. It's not just about preventing cuts; it's about enhancing the mirror's character and ensuring its longevity. The raw edge of cut glass is incredibly sharp and must always be treated, regardless of whether it will be visible or hidden. This treatment process is what defines the various edge finishes available.

Why Edge Finishing Matters

• Safety: Untreated glass edges are extremely dangerous. Finishing removes sharp points, making the mirror safe to handle and use.
• Aesthetics: The chosen finish significantly contributes to the mirror's visual style, from minimalist modern to ornate traditional.
• Durability: Properly finished edges are less prone to chipping and damage, extending the life of your mirror.
• Integration: The edge finish helps the mirror blend seamlessly with its surroundings, whether it's a feature piece or part of a larger scheme.

Arrised Edges: Practicality and Safety First

An arrised edge, sometimes referred to as a "swiped" or "pencil" edge, is the most fundamental type of glass edge treatment. It's primarily a safety finish rather than a decorative one.

What is an Arrised Edge?

When glass is cut, its edges are razor-sharp. Arrising involves gently grinding down the very sharpest points of the edge, creating a small, dull chamfer. This process removes the burrs and makes the edge safe to handle without creating a polished or decorative surface.

Pro Tip: An arrised edge is often specified for mirrors that will be installed within a frame, recessed into a wall, or otherwise hidden from view. Since the edge won't be seen, there's no need for a decorative finish, and arris-ing provides the necessary safety at a lower cost.

When to Choose an Arrised Edge

• Framed Mirrors: If your bespoke mirror will be set into a traditional frame, an arrised edge is typically sufficient. The frame will cover the edge, so a decorative finish isn't necessary.
• Recessed Installations: For mirrors designed to be flush with a wall or integrated into cabinetry, an arrised edge is practical.
• Cost-Effectiveness: As the simplest finish, arris-ing is the most economical option, making it suitable for projects where budget is a primary concern and the edge will not be visible.
• Backing and Adhesion: An arrised edge provides a slightly rougher surface compared to a polished one, which can sometimes aid in better adhesion for certain types of mirror backing or mounting systems.

While an arrised edge is safe to touch, it doesn't have the smooth, refined appearance of a polished edge. It will still have a matte, slightly textured look, reflecting the grinding process. For examples of how glass edges are treated in various applications, you might find information on glass processing standards useful, such as those discussed by BSI Group.

Polished Edges: Sleek Sophistication

A polished edge is perhaps the most popular choice for modern bespoke mirrors, offering a clean, contemporary aesthetic.

What is a Polished Edge?

Creating a polished edge involves multiple stages of grinding and buffing. After the initial cut, the glass edge is progressively ground with finer abrasives until it achieves a smooth, flat, and perfectly clear finish. The result is an edge that looks almost identical to the face of the mirror itself – transparent, shiny, and highly reflective.

Types of Polished Edges

• Flat Polished Edge: This is the most common polished finish. The edge is ground perfectly flat and then polished to a high sheen. It creates a sleek, minimalist look, ideal for contemporary designs.
• Pencil Polished Edge (Round Polished): In this variation, the edge is ground and polished to a smooth, rounded profile, resembling the curve of a pencil. This offers a softer look than a flat polished edge and can be particularly effective on thicker glass, adding a tactile quality.

When to Choose a Polished Edge

• Frameless Mirrors: For any mirror where the edges will be exposed, a polished finish is essential. This includes large wall mirrors, bathroom mirrors, and decorative pieces.
• Modern and Minimalist Aesthetics: The clean lines and reflective quality of a polished edge perfectly complement contemporary interior designs.
• Bathroom Mirrors: Polished edges are a popular choice for bathroom mirrors, offering both safety and a high-end finish that withstands humidity well.
• Feature Pieces: If your mirror is intended to be a standalone feature, a polished edge enhances its presence and quality.
• Matching Other Glass Elements: If you have other glass features in your home, such as glass splashbacks or glass balustrades, a polished edge on your mirror can create a cohesive look.

A well-executed polished edge is a hallmark of quality craftsmanship. It not only makes the mirror safe but also elevates its visual appeal, allowing light to refract beautifully through the edge itself.

Bevelled Edges: Classic Elegance and Depth

For those seeking a more decorative and traditional look, a bevelled edge offers timeless appeal and a distinctive visual flair.

What is a Bevelled Edge?

A bevelled edge is created by grinding an angle (or "facet") around the perimeter of the mirror. This angle typically ranges from 10mm to 40mm in width, gradually tapering from the surface of the mirror down to its full thickness. The bevel itself is then polished to a smooth, reflective finish, creating a prism-like effect that catches and refracts light beautifully.

Characteristics of a Bevelled Edge

• Dimensionality: The angled cut adds depth and a three-dimensional quality to the mirror, making it stand out from the wall.
• Light Refraction: The bevel acts like a prism, scattering light into a subtle rainbow effect, adding sparkle and interest.
• Timeless Style: Bevelled edges have a classic, elegant aesthetic that can suit both traditional and transitional interiors.
• Perceived Thickness: A bevel can make a mirror appear thicker and more substantial than it actually is.

When to Choose a Bevelled Edge

• Decorative Mirrors: If your mirror is a statement piece or part of a grander design, a bevelled edge adds a touch of luxury and sophistication.
• Traditional and Transitional Interiors: Bevelled mirrors complement classic decor, ornate furniture, and spaces with a more formal ambiance.
• Above Mantlepieces or Console Tables: A bevelled mirror often works exceptionally well as a focal point in living rooms or hallways.
• As a Frame Alternative: For those who desire a decorative border without a physical frame, a wide bevel can serve this purpose beautifully.

It's worth noting that bevelled edges are typically more expensive than arrised or simple polished edges due to the additional precision grinding required. However, the unique visual impact they create often justifies the investment. For insights into how such features contribute to interior design standards, you might consult resources from organisations like RIBA.

Choosing the Right Edge Finish for Your Bespoke Mirror

The "best" edge finish isn't universal; it depends entirely on your specific needs, aesthetic preferences, and the mirror's intended use and location.

Consider These Factors:

1. Mirror's Purpose: Is it a functional bathroom mirror, a decorative hallway piece, or a component of a larger installation?
2. Installation Method: Will it be framed, unframed, recessed, or wall-mounted with clips?
3. Interior Style: Does your space lean modern, traditional, minimalist, or eclectic?
4. Desired Aesthetic: Do you prefer sleek and understated, or elegant and ornate?
5. Budget: Arrised edges are the most economical, followed by polished, and then bevelled.
6. Glass Thickness: Thicker glass can accommodate wider bevels and more pronounced polished edges.

For instance, a frameless shower enclosure will always feature highly polished edges for safety and aesthetics, whereas a mirror destined for a heavy wooden frame might only require an arrised edge.

Conclusion

The edge finish of your bespoke mirror is a critical decision that impacts its safety, style, and integration into your home. Whether you opt for the practical simplicity of an arrised edge, the sleek sophistication of a polished edge, or the timeless elegance of a bevelled edge, understanding these options empowers you to make an informed choice.
