Before applying the gold, prepare an adhesive mixture—a solution of rubbing alcohol, water, and bone glue in the following proportions: 200 ml of water, 50 ml of rubbing alcohol, and a small amount of bone glue (simply dip the brush into the adhesive solution). The resulting solution must be applied very quickly and only to the areas where the gold leaf will be immediately applied. To apply the gold leaf, the book must be positioned as close as possible to the gilding pad so that the leaf can be placed on it with a decisive flick of the wrist. All work on the leaf should be done using a gilding knife, not your hands, and care must be taken to avoid creases. After placing the leaf on the pad, trim it to the size of the object, e.g., a frame, using a gilding knife with a sawing motion back and forth. Next, rub the gilding brush to charge it electrostatically and carefully place it on the trimmed leaf, peel the leaf off the pad, and place it on the surface to be gilded. Ensure that one leaf overlaps the next by a few millimeters. The range consists of several shades and metals: 22-karat gold, 22 3/4-karat gold, silver, schlagmetall in colors 2.5 and 1, aluminum, and copper. This wide range will satisfy both professionals and amateurs.
