Moonmilk
From Wikipedia, the free encyclopedia
Moonmilk is a white, cheese-like substance found inside caves. It is similar to other deposits, but its unique quality is that it does not harden or turn to stone. Analysis of the material has revealed a variety minerals.
Hypotheses about the origin of moonmilk are mixed. Some scientists think it is a bacterial action rather than a chemical one. In this theory, it is thought to be created by the bacterium Macromonas bipunctata. Certain bacterial actions are known to be capable of breaking down stone to form this semiliquid "milk".
It was originally (c. 16th century) thought to be created by "moon rays."
