Summary: Title: Metal marbles. Summary: Introduction of host, with reference to semantic playgrounds. Link to the rust converter recipe, which I found to be cheaper, and more sprayable than buckets of gel or paint-like substances which you might find elsewhere: https://www.canada.ca/en/conservation-institute/services/conservation-preservation-publications/canadian-conservation-institute-notes/tannic-acid-rusted-iron-artifacts.html In case that link moves, search for tannic acid rust converters, then choose your buffers.
