Kolner Classic Poliment—also known as bole—is a clay-like substance. It serves as a base layer for the leaf gold when gilding poliment. It is applied to the prepared surface, which is usually Gesso. Gesso is a mixture of chalk and glue. The poliment layer and the underlying layer of Gesso create a layer that permits the polishing of gold with agate burnishers. Poliment gilding can only be used on absorbing surfaces.

It is an unbound poliment (unprepared) and has to be prepared with rabbit skin glue before it can be applied. This poliment is already processed with water to a paste.

How to prepare Kolner Classic Poliment for gilding:

  1. Before using the clay (bole), it has to be prepared with rabbit skin glue before it can be applied. This clay is already processed with water to a paste, but you need to add some Rabbit Skin Glue to it first.
  2. Add one part Poliment and one part rabbit Skin Glue (liquid form) depends on how thick or thin you want your clay to be.
  3. The rabbit skin glue must be warm when adding it to the poliment. Mix gently not to create air bubbles and until the texture is consistent, runny and smooth.
  4. For best results, apply two to three thin coats of this clay onto a perfectly smooth surface, such as Gesso.
  5. After the classic poliment has dried, polish the surface with the Steel Wool Pad or with the Fiber Clouth to a perfect state. Your classic poliment at this point must look clean, shiny, smooth and free from dust.
  6. Prepare the gold leaf water using the rabbit skin glue tablet or use a pre-made Kolner Colnafix Gilder’s Size. This mixture will make the clay surface a little wet for the gold leaf to stick.
  7. Apply the gold leaf, and let it dry for at least 5 hours.
  8. Your gilded surface is now ready to be burnished with the Agate Burnisher Stone.
  9. Buff any gold flakes that sits on the surface with the Gilder’s Wool Brush.
  10. Normally, 24k gold leaf does not need to be varnished to protect it from oxidization. However, for less than 24k, use Kolner Leaf Protect Varnish to seal the surface.
