Inscriptions are essential for all bells intended for religious buildings. They are made of red wax and applied to the false bell. Using very fine brushes, the false bell is then coated with several layers of a mixture of clay, horse dung, and goat hair. Once the coating is thick enough, a charcoal fire is lit under the bell mould. The letters and wax decorations melt and leave their imprint in the mould. This lost wax technique has always been used at Cornille-Havard.
