Gilding:
Gilding is an ancient decorative technique that applies a thin layer of gold leaf, gold powder, or other metal foils to surfaces such as wood, metal, stone, porcelain, or glass. Objects treated in this way are called gilded or gilt.
Genuine gold leaf, usually between 22k and 24k, is the traditional standard. However, the term can also refer to using other metals like
silver,
copper,
palladium,
aluminium, or
imitation gold such as Dutch metal or brass.
Water Gilding:
Water gilding is a specialised traditional technique primarily for wood. The surface is prepared with layers of gesso (chalk and glue) and a smooth clay called bole. Water activates the glue in the bole, enabling the gold leaf to adhere. Once dry, the gold can be burnished with an agate stone to achieve a mirror-like shine.
Edible gold leaf:
Edible gold leaf is a popular for culinary applications for decorating cakes, desserts, and cocktails.
Imitation / Composition gold leaf:
Composition gold leaf is a budget-friendly alternative (such as Dutch metal or brass leaf).
Size / Gold size:
The specific
adhesive used to bond the delicate leaf sheets to a surface.
Oil/size gilding is a versatile technique suitable for most non-porous surfaces, including outdoor architecture. Apply a sticky oil- or water-based adhesive, known as size, to the surface. Once the size reaches the proper tackiness, the leaf is carefully placed. The finish produces a soft matte glow but cannot be burnished to a mirror shine.
Agate burnisher:
A commonly traditional
burnishing tool used to polish and shine gold leaf after application.
Transfer leaf:
Refers to leaf attached to tissue paper for easier handling compared to loose leaf.
When to Choose Loose Leaf:
Intricate or Carved Surfaces: It easily conforms into deep grooves, dents, and elaborate ornamentation, making it the top choice for highly detailed antique picture frames, mouldings, and sculptures.
Key Challenges & Application Tools:
Handling Difficulties: Avoid touching loose gold leaf with bare fingers, as skin oils and static electricity may cause tearing or sticking. Even minor drafts can displace the leaf.
The Gilder’s Pad & Knife:
Professional gilders use a
cushioned pad to hold loose leaf and cut it to size with a Gilder’s Knife.
The Gilder’s Tip:
Artists use a very thin brush called a
Gilder’s Tip to pick up the sheet. By gently swiping the brush across skin or hair, they create a slight static charge that lifts the loose leaf without causing damage.
