Gilding on Glass versus Eglomise
Gilding on glass and églomisé (reverse gilding) are similar techniques involving the application of gold leaf to glass, but they differ in purpose, method, and finish. Here’s a comparison to highlight the distinctions:
1. Definition and Purpose
Gilding on Glass:
- Involves applying gold leaf to the surface of the glass, typically the front side.
- Used for decorative purposes, such as embellishing windows, mirrors, or glassware.
- The gold finish is visible on the surface, providing a reflective and metallic effect.
Églomisé:
- A French term referring to the process of reverse gilding and painting on the back of the glass.
- Gold leaf is applied to the reverse side of the glass and then often combined with painted designs.
- Creates a smooth, reflective surface on the front, with the gold and decoration visible through the glass.
- Used in fine art, signage, and high-end decorative pieces.
2. Application Process
Gilding on Glass:
- The surface of the glass is cleaned and prepared.
- Gilding adhesive (size) is applied to the front of the glass.
- Gold leaf is carefully applied to the adhesive and smoothed out.
- Excess gold is brushed away, and a sealant may be added for protection.
Églomisé:
- The reverse side of the glass is cleaned and prepared.
- Gilding adhesive (or water gilding techniques) is used to attach gold leaf to the reverse side.
- Designs or backing paint are applied over the gold to create patterns, protect the gilding, and enhance the appearance.
- When viewed from the front, the gold and designs are seen through the glass.
3. Visual Effect
Gilding on Glass:
- The gold appears directly on the surface, often with a textured finish depending on the application.
- The look is bold and striking, with the gold being prominent.
Églomisé:
- The gold is viewed through the glass, creating a smoother, more refined appearance.
- Often combined with painted designs, it gives a layered, intricate aesthetic with a glossy, glassy surface.
4. Durability and Protection
Gilding on Glass:
- The gold is exposed on the surface and more prone to wear, scratching, or tarnishing if not sealed.
- Sealants can protect the finish but may slightly alter the sheen.
Églomisé:
- The gold leaf is protected by the glass itself, making it more durable and resistant to damage.
- Paint backing further shields the gilding.
5. Common Uses
Gilding on Glass:
- Decorative glassware
- Mirrors (edges or frames)
- Windows or architectural glass
- Art installations
Églomisé:
- High-end furniture panels (e.g., tabletops, cabinet doors)
- Luxury signage
- Decorative panels or wall art
- Fine art glasswork
Key Differences
| Feature | Gilding on Glass | Églomisé |
|---|---|---|
| Location of Gold | Front of glass | Back of glass |
| Designs | Gold typically stands alone | Often combined with painted designs |
| Durability | Exposed, less durable | Protected by glass, more durable |
| Finish | Textured and metallic | Smooth and reflective |
| Applications | Functional and decorative glassware | High-end decorative and fine art |
Conclusion
Both techniques have their charm and applications, but gilding on glass emphasizes bold, exposed gold, while églomisé is more refined, protected, and often involves artistic designs. The choice depends on the desired aesthetic, level of durability, and purpose of the piece.
