How do I make furnace-like blocks?

I need help making a thing where you can turn an item into another item and it works like a furnace. Although I can make a furnace recipe, it wouldn't make sense for what I am doing since furnace is SMELTING and not CONVERTING. I haven't found any good tutorials and most of the videos are blurry. Please help me!!

Note: I am on 2026.1 so this is where energy and fluid is added into MCreator.

So just make a custom…

So just make a custom furnace, custom block, custom gui, create a procedure on gui tick, find the template for custom furnace of crafting table etc. You get if slot 1 = item1, set slot 2 to item2. Then when item is taken from slot2 clear items from slot1 or remove 1 item from slot1 etc

For a timer, use a number nbt, count it down on block tick, when timer = 0, get item in slot1 = item 1 and set item in slot2 to item2. If no item is in slot 1 set counter to 0.

Then for multiple recipes, you just do more checks for what item is where, you can then amend the time taken
