found common symbols between ores and bars (iron, copper, gold) and tools (replace iron with steel).
iron, copper, and steel have very similar symbols; they look like something shiny under a hill, followed by another shape. Copper and steel 2nd symbol looks similar, but the shape inside the container is different. Don’t really see similarities between those and iron’s second symbol.
Gold is different entirely. It looks like a little shrine, or a slightly different shape under the hill. No second symbol.
Ore has the shape for stone in it, and the first symbol of the pair symbol for ore is the same as the first symbol for iron and copper: something shiny under a mountain.
glow ring ‘glow’ looks like a thing that’s glowing
Sun. for sunday and Summer have the same shape
