Block of Copper
Copper Block starts as a vivid orange metal and slowly oxidises through four stages to seafoam green — the only block that visibly ages over time.

Description
Copper Block is crafted by filling a 3×3 grid with nine ingots — the largest ingot-to-block conversion in the game. Freshly placed, the surface is a vivid orange-brown that catches torchlight like polished metal. Left alone, copper passes through four random-tick oxidation stages: fresh, exposed (green flecks appear), weathered (mostly green with orange remnants), and finally oxidized — a uniform pale seafoam green that builders often deliberately target for aged or coastal aesthetics.
The oxidation can be frozen at any stage by right-clicking with a honeycomb, which waxes the surface and permanently locks the colour. Conversely, an axe scrape removes one layer (or strips the wax first), and a lightning strike near an unwaxed copper block reverts it fully back to the original orange. This makes copper the most mechanically interesting building material in the vanilla palette: identical blocks placed at different times look different, the wax mechanic gives full control over the preferred stage, and four blocks of any stage decompress back into nine ingots without loss. The same oxidation system extends to cut copper, copper stairs, and copper slabs — every shape ages in lockstep.
