Giusto Manetti Battiloro 2ZDB21P Agatpolerer N 21

Gilding burnisher. The agate burnisher Brunitoio is a traditional gilding tool designed for polishing surfaces gilded using the water‑gilding technique. It consists of a wooden handle and a smoothly polished agate stone tip, available in various shapes and sizes.

Agate is an exceptionally hard, smooth, and non‑abrasive mineral, allowing the creation of a high, mirror‑like shine without damaging the gold leaf. Different tip shapes are used depending on the geometry of the surface, particularly for:

• polishing large areas
• enhancing contours
• transitions between reliefs
• refining ornamental details
• working in narrow or hard‑to‑reach areas

The agate burnisher Brunitoio is an essential tool in traditional water gilding, where gold is mechanically burnished to a high gloss after drying and gentle re‑moistening. For optimal performance, we recommend warming the stone slightly by rubbing it against a wool cloth before use. Agate tips are highly sensitive to scratches and damage, so careful handling is necessary.
