"Ability to smelt two different items in one

I suggest adding a new furnace feature that allows players to smelt two different items at the same time to create advanced or combined materials. This would work like a dual-slot input system where, for example, combining sand + iron might create reinforced glass, or sand + copper could result in a new decorative or strong building block. This system could be used for: Creating new building materials with unique textures or properties Introducing more complex crafting recipes, making the game more engaging Improving the usefulness of the furnace and giving players more reason to experiment This would make Minecraft feel deeper and more creative, especially in late-game or technical builds. It also gives a new reason to collect and combine materials in smarter ways.
