FOSS gamedev and creative worlds

i want to make a mod where you need to combine a lot of things. one of these is very expensive, so how would i make it so when you smelt it it gives you two items

example: obsidian+bucket=obsidian filled bucket
smelting obsidian filled bucket= super obsidian AND bucket (it gives you the bucket back

thanks for any help

EDIT: how would i make it so a craft with a water bucket would give you the output but leave an empty bucket in the crafting grid afterwards so you wont have to keep making buckets

I think that the mod (might be moretrees) that has palm trees allows you to craft coconuts with a glass and an axe to get a glass of coconut milk and it gives an axe back. You might want to check that out and see how it accomplishes this. There may be other mods that can do similar things but this is the only one that I have heard of.

K thanks
