Applying gold leaf involves a process of adhering thin sheets of gold to a surface. Here's a breakdown of the steps:
Steps for Applying Gold Leaf
-
Prepare the Surface: Ensure the surface is clean, smooth, and free of dust or debris. You may need to sand and prime the surface for optimal adhesion.
-
Apply Adhesive (Size): This is a crucial step. The adhesive, often called "size," is what the gold leaf will stick to. The type of size you use will depend on the desired finish and the project.
- Oil-based size: Dries slowly and allows for a longer working time, suitable for detailed work and achieving a very shiny finish after burnishing.
- Water-based size (Acrylic Size): Dries quickly and is easier to clean up, good for beginners and faster projects.
- Apply a thin, even coat of the appropriate size to the area you wish to gild. Follow the manufacturer's instructions regarding drying time. The size needs to be "tacky," not wet or completely dry, to properly adhere the gold leaf.
-
Lay the Gold Leaf: Carefully remove a sheet of gold leaf from its packaging. Gold leaf is extremely delicate. You can use a gilder's tip (a wide, flat brush) to pick up the leaf or carefully transfer it with your fingers (wearing gloves can help). Lay the gold leaf onto the sized surface, overlapping edges slightly (approximately 1/8 inch).
-
Apply Additional Gold Leaf (If Needed): Continue laying gold leaf sheets until the entire area is covered. Any gaps or imperfections can be filled in with small pieces of gold leaf.
-
Pat Down the Gold Leaf: Gently pat the gold leaf onto the sized surface using a soft cotton ball or a gilder's mop (a soft brush). This helps to ensure good contact with the adhesive.
-
Burnish (Optional): If you desire a highly polished finish, carefully burnish the gold leaf using a burnishing tool (agate or stone burnisher). Burnishing compresses the gold leaf, creating a smooth, reflective surface. Oil-based size works best for burnishing.
-
Remove Excess Gold Leaf (Skimming/Brushing): After the adhesive has dried completely, use a soft brush (like a gilder's brush) to gently sweep away any loose or overlapping gold leaf. This reveals the gilded areas and creates a clean, finished look.
-
Seal the Gold Leaf: Applying a sealant is essential to protect the gold leaf from tarnishing and abrasion.
- Use a clear, non-yellowing sealant specifically designed for gold leaf.
- Apply thin, even coats of sealant, allowing each coat to dry completely before applying the next. Follow the sealant manufacturer's instructions.
Tips and Considerations:
- Working Environment: Gold leafing is best done in a dust-free environment, as even small particles can adhere to the gold leaf and create imperfections.
- Practice: Gold leafing takes practice. Start with small projects to develop your skills.
- Types of Gold Leaf: Gold leaf comes in different karats (purity) and shades. Choose the appropriate gold leaf for your project. Imitation gold leaf (metal leaf) is also available, which is more affordable but less durable and prone to tarnishing.
- Safety: Wear gloves to avoid transferring oils from your skin to the gold leaf.
By following these steps, you can successfully apply gold leaf to a variety of surfaces and create beautiful and elegant gilded objects.
