Is This Smeltable?

IsThisSmeltable

Playing a heavy modpack with hundreds of new ores and materials? Tired of guessing which ones can actually go in a furnace?

IsThisSmeltable solves that instantly. Simply open any inventory and press H — every item that can be smelted in a vanilla furnace will light up with a green overlay for 3 seconds, giving you an immediate visual answer with no guesswork required.

Works with every mod automatically. If a mod registers a furnace recipe, IsThisSmeltable will detect it. No configuration needed, no lists to maintain — it just works.

Features:

• Press H with any inventory open to highlight smeltable items
• Green overlay lasts 3 seconds then disappears cleanly
• Works in your player inventory, chests, hoppers, and any other container
• Fully compatible with all mods that use the vanilla furnace recipe system
• Rebindable in Options → Controls
• Client-side only — no server install required

Perfect for modpacks like GregTech New Horizons where hundreds of ores flood your inventory and only some of them belong in a furnace.
