« This new material has the molecular elasticity of a snail and the consistency of the train station of Perpignan »
In 1968, Jacques Daum meets with Salvador Dalí inCadaquès, Spain, to suggest a collaboration in imaginingsculptures in pâte de cristal (crystal paste, a uniqueproprietary technique by Daum. Dali, very interested bythis prospect, declares: "Pâte de cristal is truly a Dalinianmaterial. Hence I have used it to create masterpieces;I'm delighted by this new material, which has both themolecular elasticity of a snail and the consistency of thePerpignan train station". Daum and Dali's collaboration lasted over 20 years, and resulted in 28 artworks in pâte de cristal.
1. Molding the model
The craftsman uses a sketch to make a fi rst clay model. Volume, details and expressions are worked to perfection. Once the sculpture is finished, a negative mold is made out of elastomer.
2. Wax pouring
DHot wax is poured into the hollow mold after the original sculpture is removed.
3. Wax reproduction
When the wax has cooled and set, the model is removed from its elastomer mold.
4. A perfect reproduction thanks to the lost wax technique
The wax model is then chiseled and reworked by hand in order to obtain a perfect reproduction that is identical to the original. The wax model is immersed in refractory plaster. Under the effect of heat, the wax melts and drips from the plaster through previously made holes.
5. Filling the mold with pieces of crystal
When the wax cleared, the hollow part of the plaster mold is carefully fi lled with pieces of crystal of different colors and sizes. These pieces of crystal are also called groisil. Everything is then put into ovens at 1 400° for many hours, depending from the size of the pieces.
6. Unmolding and finishing the sculpture
After cooling, the plaster mold is delicately broken, revealing the pâte de cristal sculpture.
7. Finishing and Signature
Quality control and color distribution takes place after finishing operations. The piece is then ready for the final touch: the Daum signature and the artist's signature, depending on the case. The process is then repeated for each piece. Every work is unique.
