Periostracum or not periostracum ?

[david touitou]

hello,

Everything have been said. I rarely keep a cone shell with it's periostracum. Though if you have several specimens, you could keep from time to time one with and have an original shells. Like for the others, you may use mineral oil to make the periostracum looks like when it was in the water.

Strong bleach solution but I would not say overnight. I mean, when you see that the periostracum have been removed, do not let shells more. I remark that with the ours, the % of bleach in the solution gows down, especially if you have many shells. And if bleach in not enough concentrated, and if you forget your shells in, you will have white marks. Even if mineral oil helps, I prefer not to have these...

happy Shelling,
DAVID
