This gypsum bas-relief panel from ancient Mesopotamia, now in the British Museum, shows ancient Assyrians using inflated goatskin bladders as floats 3000 years ago.
3000 years carved gypsum? perhaps this form should be used in housing vs the crushed,pressed stuff that lasts some years at best, or only minutes when exposed to running (leaking) water.
