The treated area is limited to the immediate vicinity of the staple. The absence of mechanical methods reduces the risks of flaking, cracking, scratches and breakage. The staple is conserved and stabilized.

The objective is to determine the structure and composition of the patina through the depth profiles of the constituent elements, particularly C, N, O, obtained by (d,p) nuclear reactions.

This investigation was launched by the mineralogist Alexandre Brongniart in 1805, requesting thirty-six préfets to make a survey of the raw materials and of the pastes and glazes recipes in their respective départements. This investigation, which lasted until 1810, resulted in a large number of reports and letters, together with clay and pottery samples.
