iron dust don't smelt in eletric furnace or vanilla furnace

Sorry about that, another missing recipe. Since Cotton Resources was removed I need to add these recipes myself and I forgot a few. The next update with it fixed should come out sometime this week. A quick solution, if you want, is add another mod that adds this recipe (TechReborn or even Cotton Resources). I'm very sorry.

you could also just throw in a datapack. you cna use https://crafting.thedestruc7i0n.ca/ to make the recipe and datapack for the regular smelter

Fixed as of 1.2.0-BETA which you can download here
