Applying gold leaf to pottery involves a delicate process that often utilizes static electricity for precise placement. Here's a breakdown:
-
Prepare the Surface: The area where the gold leaf will be applied needs to be clean and prepared with an adhesive specifically designed for gilding, often called "size." This size can be water-based or oil-based, and the choice depends on the desired finish and drying time. Ensure the size is tacky but not wet before applying the gold leaf.
-
Creating Static (Simplified): One technique involves using a soft brush, like a gilding brush or even a clean, dry paintbrush. You gently stroke the brush through your hair (or a piece of fur or silk) to generate a small amount of static electricity. Avoid overdoing it, as excessive static can make the leaf difficult to control.
-
Lifting the Gold Leaf: Carefully hold the statically charged brush over the gold leaf. The slight static charge will attract the lightweight gold leaf, causing it to lift and adhere to the brush.
-
Applying the Gold Leaf: Position the brush with the gold leaf over the prepared area on the pottery. Gently touch the gold leaf to the tacky size. The adhesive will secure the gold leaf in place.
-
Smoothing and Burnishing: Once the gold leaf is in position, use a soft brush or a burnishing tool (agate is common) to gently smooth it down, ensuring it adheres firmly to the size and removes any air pockets. Burnishing will also enhance the shine of the gold leaf.
-
Removing Excess: Any excess gold leaf can be carefully brushed away with a soft brush. This excess can be saved for future projects.
-
Sealing (Optional): Depending on the intended use of the pottery, a sealant may be applied to protect the gold leaf from wear and tear. Ensure the sealant is compatible with both the gold leaf and the pottery finish.
Important Considerations:
- Ventilation: Work in a well-ventilated area.
- Patience: Applying gold leaf requires patience and a steady hand.
- Materials: Use high-quality gold leaf and gilding size for the best results. There are imitation gold leaf products available which are significantly cheaper, but don't have the same luster and may tarnish over time.
