Did you know that when a scallop shell is whole (still attached to its mate), the two sections are completely different colors? I didn't. You learn something new every day. The light-to-white top shell is paired with a gray-to-black bottom.
Our collection is mostly soaked and brushed at this point. We found three pieces of sea glass, one of which has smoothed edges but has not been tossing around for anything like 20-30 years. The white piece is the oldest; it has the most burnish to it.
