The first time I recognized the word ‘ciselant’ was when reading the book ‘Lipstick Traces’ from Greil Marcus (Rowohlt Verlag, 1996, S. 239):
Neben den vorherbestimmten Stadien von Ausdehnung und Zersetzung existiere noch eine weitere Möglichkeit: die des ‘ciselant’ (ausfeilen).
This is in one Chapter which is mainly about Isidore Isou.
One of the not numerous pages I found on the web when searching for ‘ciselant’ was one with a reference to Isidore Isou (Jean-Isidore Goldstein), “La Photographie ciselante, hypergraphique, infinitesimale et supertemporelle” ( SANDRO RICALDONE WEBPAGES: LETTRISME. A CHRONOLOGY, ISIDORE ISOU, LETTRISME).
I do not know the exact meaning of the french ‘ciselant’ but found the following english and german similare words:
chisel steel tool with a bevelled edge for shaping wood, stone or metal. 1. cut or shape with a ~: ~led features, (of a persons’s appearance) clear cut; well modelled. 2. (colloq) cheat; swindle. ~-ler person who ~s [Oxford Advanced Learner’s Dictionary of Current English, A S Hornby, 1983 Berlin].
Ziseleur <franz.> u. Ziselierer (Metallstecher); ziselieren ([in Metall] mit Punze, Ziselierhammer [kunstvoll] einarbeiten); [Duden, Rechtschreibung der deutschen Sprache 1996].
Amazing, but true there is another domain name inspired from the above quoted sentence of Greil Marcus (but from the english version of the book). I found it recently searching the web for ‘ciselant’. For further information see www.compost-records.com.
