Designed by Eugénie Bidaut and Benjamin Gomez as part of the Reviving Ange Degheest project at EESAB. Allegedly based on undated lettering made by (fictional) type designer Ange Degheest. The original plate shown by Velvetyne is titled Égyptienne imitation de gravure and appears to have been published by Emile Thézard in Nouveaux modèles de lettres around 1890. Basalte comes in color font format as well as in Fond and Volume styles that can be combined for bichromatic effect.
