▸ The reading

interpretive · art

Rhenium rides inside jet engines as single-crystal superalloy turbine blades — spinning at ten thousand rpm while glowing yellow-hot, third-highest melting point on the table holding the line. One of the last stable elements discovered, 1925. The late arrival assigned immediately to the hottest post.
