Although it has some drawbacks and requires thoughtful storage and care, many antique and vintage items made from this early plastic are highly collectible.Early experimentation with celluloid or French ivory focused on the manufacturing of a substitute for costly natural ivory billiard balls.During the late 1990s and early 2000s more ivory figurines of animals and birds, all dating from the Aurignacian culture of the Upper Paleolithic, were found at various sites in the region.
The woolly mammoth figurine - the first of the dozen or so Paleolithic Stone Age figurines discovered in Swabia to be recovered intact - measures 3.7 centimetres in length and weighs only 7.5 grams.
Sculpted in exquisite detail using stone tools, it has a slim form, pointed tail, powerful legs and arched trunk.
Extreme heat and cold, along with high humidity or direct sunlight, can damage French ivory.
Oils, alcohol-based perfumes, makeup and other chemicals should be kept away from items made from celluloid.
Billiard balls made of it were said to break occasionally on contact, and the material is highly flammable. It also is easily stained by perfumes and oils, making French ivory jewelry and accessories less durable that those made from the natural materials that this substance mimicked.
Along with producing celluloid that resembled ivory, colors were created to mimic tortoiseshell, coral and amber, which also are expensive natural materials. Beads, broaches, fancy hair combs, hatpins and other accessories made of ivory-colored celluloid are readily found in antique markets and collectible vintage jewelry shops.
A less-harmful test involves holding the piece in hot water for several seconds, and if it gives off a camphor smell, like mothballs, it probably is celluloid.
This early plastic also can be identified by its light weight and translucent nature when held to the light.
The Swabian Jura, a plateau in the German state of Baden-Württemberg, is home to a large number of prehistoric caves and rock shelters (including Vogelherd, Hohlenstein-Stadel, Geißenklösterle and Hohle Fels) that have attracted the interest of Paleo-anthropologists and archeologists ever since the early 20th century.
Several were successfully excavated in the early 1930s by the Tubingen archeologists Gustav Reik and Robert Wetzel - see, for instance: the Lion Man of Hohlenstein Stadel (c.38,000 BCE).
All the artifacts were found at the site of the Vogelherd Cave in the Swabian Jura, in southern Germany.Tags: Adult Dating, affair dating, sex dating
