Instances of crystalline efflorescence were observed on two objects on display at the Oriental Institute Museum. The most spectacular of these instances involved soft, white, needle-like crystals measuring more than 1 cm in length. Different analytical techniques were employed in an effort to identify the crystals including scanning electron microscopy, microchemical testing and x-ray diffraction. The conservation treatment of the efflorescence involved both mechanical cleaning and desalination by poultice.
