Alabaster

Alabaster – At Antiparos in the Aegean sea, the ancients used alabaster for incense and for funeral urns. If it turned yellow and lost its whiteness, it meant sickness and famine would come.

Church statues made of alabaster are sometimes found to be chipped, in many cases this damage is purposeful. Powdered alabaster was once used to make an ointment for those with bad legs, and some believed that alabaster taken from holy statues had extra restorative power.
