Conserving the Ain Ghazal statues

From the Visit Madaba twitter feed, this is an intriguing (if you have archaeology geek tendencies) video on the conservation of the Ain Ghazal statues from Jordan. These wonderful, spooky, atmospheric figures (some of which are in the archaeological museum in Amman, some in the BM and some in the Louvre) are over 9,000 years old and, if memory serves me right, pre-date fired pottery in the area, but are made of some kind of gypsum (like plaster).
