Staffor ornemanist
Under the name of staffor ornemanist hide in fact several distinct trades, but having all the joint fact of employing the plaster and the Filasse (vegetable binder).
Most widespread is that which consists in creating objects of decoration of interior or outside like the Rosace S, the Pilastre S, the Corniche S, the Coupole S (Valley of Europe), the coffered ceilings (Museum of orsay http://www.musee-orsay.fr), the decorative Plafond S or of simple plasterboards armed with oakum, and posing them. There are thus workmen with the workshop and others which are specialized in the installation (they are seldom the same ones).
The staffor can also reproduce objects as Statues (there is for example a workshop of staffor to the Musée of Louvre), reproduce or restore whole or part of ornaments (museum of the French monuments http://www.citechaillot.fr), produce prototypes (there is a workshop of staffor to the style Peugeot vélisy and Renault guyancourt), manufacture decorations for televisual animations or the laminate cinema (workshop of the decoration of the SFP with Bry on Marne), to make models worked by modelling or cutting (Corinthian capital, cornices etc), to mould alive models thanks to the Alginat, to transform an actor into old man but too to create monsters or animals finally raliser of the low-size moulds thanks to the Latex, to repair old executives out of wooden covered with a fine layer of Carton hones by grinding the missing parts and to replace them by resin polyurethane or plaster mouldings, finally to patinate the mouldings plasters some (see with moulage" in plâtre").
Technical To obtain a cornice which can be posed, the way is long…
Staffeur initially will cut out in a plate of Zinc (1) the opposite profile which the cornice will have, it will drown zinc in Plâtre (2) to prevent it from becoming deformed. Then, on a marble plate, it will create a “wood sledge” (3-4) which it will maintain using " bolsters of plasters and oakums (5). Once the dry sledge, it will pour plaster in front of and will push it (6), which will format the plaster. Once finished one obtains a mould (7). the dry mould, one coats it “Barbotine” to prevent the plaster from sticking, and one it “staff”, which means that one soaks the brush to be constructed in staff (8) in the liquid plaster, and of an epic of the hand, one projects the plaster on the mould; once the first finished layer one will place a layer of oakum, and over another layer of plaster using a Couteau to coat (9) or of a Riflard (10); the surpluses will be withdrawn. It does not remain any more which the test has to unmould and to start again with the n°7.
