Compacting Drawers

A compacting drawer automatically converts between three forms of the same material: nuggets ↔ ingots ↔ blocks (or planks ↔ logs, etc.). Place one and put any of the three forms in — the drawer recognises the recipe and rebalances the count.

For example, a compacting drawer holding iron will accept iron nuggets, iron ingots, or iron blocks, and show each at the correct ratio (9 nuggets = 1 ingot, 9 ingots = 1 block). Pulling out an ingot can decompose a block; pulling a nugget can decompose an ingot. No more "I have iron blocks but I need nuggets" hunts.

Compacting drawers work best for materials with the standard 3×3 recipe chain — most metals, gems, redstone, lapis, glowstone, and wool.
