Pâte de Verre (French, “glass paste”) is a material produced by grinding glass into a fine powder, adding a binder to create a paste, and adding a fluxing medium to facilitate melting. The paste is brushed or tamped into a mould, dried, and fused by firing. After annealing, the object is removed from the mould and finished.
It first appeared in Egypt around 1570BC. Sculptor Henri Cros reintroduced the process for large relief sculptures. The technique was furthered and refined into vessels by Albert-Louis Dammouse from 1898 and by Francois-Émile Deecorchement from 1900.
