Genuine gold leaf is used for both indoor and outdoor gilding. However, to avoid oxidisation, it would help if you used at least 23k for outdoor gilding. Genuine gold leafs are available in transfer and loose form. The transfer leaf is best for outdoor gilding where wind and draft make it challenging to handle the loose leafs. The transfer leaf is also best for dry gilding using Instacoll Size or Permacoll Size. For water gilding, use the loose gold leaf. They work better on a wet surface.

Due to camera and lighting conditions, the gold leaf photos and the actual gold leaf have colour variations.
