The Rosetta Stone

These two tiles identify which type of wood is used for each group of elements (for example, the Rare Earth Metals are Red Oak).
By the way, I call them Rare Earth Metals instead of just Rare Earths because they are metals, and by including that in the name it makes it clear that almost every group on the table is one form or another of a metal, a metalloid, or is defined in terms of not being a metal, which is interesting.
I use the obsolete term Metalloid because I like it.
