A Coal Block is a compact way to store coal, which is a common resource used for fueling furnaces or crafting torches. Crafted from nine pieces of coal, it provides a dense storage option or can be used as a decorative block. When broken apart, it returns nine coal, making it an efficient means of transport and storage for large quantities of coal without loss. It also serves as a more potent fuel source, burning for a longer duration than individual coal pieces.
