Hydromagnesite (Inventory)/Powder
From LagWiki
The Powder field of the Hydromagnesite section should record any observation of the powdery form of moonmilk.
The powdery form of moonmilk can be any of a number of minerals including hydromagnesite, dolomite, huntite, calcite, aragonite, and others. The powdery form is usually white and looks like talcum powder. It is basically dehydrated moonmilk or corroded calcite. Any observation of powdery moonmilk should be recorded in this field as it is difficult to determine the specific mineral content without testing. The powdery form of moonmilk is usually found on the floor or shelves as it does not adhere well.
