Hi,
Has anyone used "iron Out" with siderite nodules? Years ago I collected some Mazon Creek nodules, but although some fossils are present, they are either faint or encrusted with some type of mineral. I was wondering if it was advisable to use an Iron Out solution to enhance the fossils or will they be obliterated? If Iron Out can be used, how long should the nodules remain in the solution?
Thanks,
ODK
