First, the core and outer envelope of the Deux Cigales flacon, designed by Lalique’s design studio, are made in plaster. In the final flacon, the motif will be molded on the interior of the bottle, and the amber hue of the precious fragrance will reveal the cicadas.
The artisans use these plaster sculptures to fashion two elastomer molds, one of the outer shape and the other of the core. The flexibility of elastomer allows the demolding of the most intricately detailed shapes, such as the delicately veined wings of these cicadas. Poured into the elastomer mold, the wax takes on the shape of the flacon.
This wax sculpture is then placed inside a plaster case, into which refractory plaster is poured. The wax melts away in the heat.
The resulting hollow reveals the shape of the piece. A block of crystal is then placed inside a plaster cup, on top of the mold. Heated in the kiln, it slowly melts into the imprint.
It is then very gradually cooled and the plaster removed. As the plaster mold is destroyed at this stage, a new one must be made for each piece.
The unfinished piece moves on to the “cold glass” workshops. At Lalique, the finishing stages make up two-thirds of the production process.
The piece is cut, sandblasted and chiseled to remove surplus crystal, before being polished and satin-finished. Every piece being unique, each flacon is permanently paired with its own stopper.
