Copper Bulb block in Minecraft
The Copper Bulb is the fresh, orange stage. A copper bulb toggles its light on or off with each redstone pulse, and shines less as it oxidizes: 15, 12, 8, then 4. 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 Blaze Rod, 3 × Block of Copper and Redstone Dust. It is mined with a pickaxe (at least tier stone). It gives off light up to level 15, depending on its state.
