Picture frames typically include glass primarily to protect your treasured photos and artwork. This protective layer shields the image from various environmental factors and physical damage, helping to preserve its condition over time.
According to the provided reference, glass in photo frames is specifically intended to protect your photos. This is its main function, acting as a barrier against elements that can degrade or harm the picture or print.
Key Purposes of Picture Frame Glass
While simple, the glass serves multiple important protective functions:
- Dust and Dirt Protection: It prevents airborne particles from settling directly onto the surface of the photo, which can cause abrasions or stains over time.
- Moisture and Humidity Barrier: Glass helps to create a sealed environment that reduces the impact of fluctuating humidity and prevents moisture from directly contacting the print, which could lead to warping or mold.
- UV Light Filtering: Many modern types of frame glass offer some level of UV (ultraviolet) light filtration. UV rays are a major cause of fading in photographs and artwork, and while standard glass offers minimal protection, specialized glass can significantly reduce this effect.
- Physical Protection: It guards against minor physical contact, such as accidental touching, scratches, or spills.
Types of Protection Provided
| Protection Type | Description | Benefit |
|---|---|---|
| Dust & Dirt | Blocks airborne particles | Prevents surface damage and buildup |
| Moisture | Creates a barrier against humidity/spills | Avoids warping, mold, and water damage |
| UV Light (often specialized glass) | Filters harmful ultraviolet rays | Reduces fading over time |
| Physical Contact | Guards against touches, scratches, light bumps | Protects the image surface from harm |
Potential Risks and Downsides
Despite its primary purpose of protection, using glass in picture frames isn't without its drawbacks. As the reference points out:
- Risk of Breakage: "If you ever drop the frame or bump it the wrong way the glass can crack or shatter!" This is a significant risk, particularly with larger frames.
- Safety Hazard: "The sharp edges are dangerous to both your print and yourself." Shattered glass poses a risk of cuts and can also scratch or tear the photo it was meant to protect.
- Glare: Standard glass can cause reflections, making it difficult to view the picture clearly, especially under direct light.
- Weight: Glass adds considerable weight to the frame, which can be a factor when hanging large pieces.
Alternatives
Due to these risks and downsides, some frame manufacturers use alternatives like acrylic (plexiglass), which is lighter, less prone to shattering, and often offers better UV protection. However, acrylic can scratch more easily than glass and may develop static cling.
In conclusion, the inclusion of glass in picture frames is a traditional and effective method intended to protect your photos from environmental damage and physical contact, although it does come with the inherent risks of breakage and sharp edges if mishandled.
