How to make a Copper Golem and sort items with it
Place a Block of Copper (9 Copper Ingots), then put a Carved Pumpkin or a Jack o'Lantern on top of it.

The Block of Copper is the fresh, orange stage. Nine copper ingots make one, and it is the starting point of cut and chiseled copper. Copper ages in four stages, from orange to green, unless you wax it with a honeycomb; an axe scrapes off one stage or the wax.
It is made with the Crafting Table from 9 × Copper Ingot. It is mined with a pickaxe (at least tier stone).
