I found something to do with all the zinc pennies I have been digging. I have a lot more of ate up ones, but I put the worst ones in this glass block. May try and use it as a bookend or something. Just another goal this year--to fill my glass block.
My collection could probably fill that and then some, been at it for years! I need a solution to stop them from further corroding from the ocean salt, or I will have a container of corroded crud.
