Hydromagnesite (Inventory)/Crinkle Blister
From LagWiki
The Crinkle Blister field should be used to record stations which exhibit cave blisters.
Crinkle Blisters are thin, hollow balls that form on cave walls and other speleothems. Most blisters are made of calcite or gypsum and are rarely more than a few centimeters in diameter. They can sometimes appear as curling flakes. The thickness of the walls can range from half a millimeter to almost one centimeter. They are formed from pasty minerals which have dried. They sometimes appear in blobs like shaving cream.
