Byne's Disease from storage method of shells

[paul monfils]

No, this is not anything that can affect humans or animals. In fact, it is rather imaginative to refer to this problem as a "disease". It is simply a chemical reaction between acid vapors released from some wood products, and the calcium carbonate of the shells. It can cause the shells to become somewhat dull over a long period of time, or in extreme cases, to develop a fine dust-like residue. If you want to see a greatly accelerated example of this reaction, drop a shell you don't need into vinegar.
