Smelting Clusters into Ingots and Nuggets

Clusters to Ingots

Every metal Cluster smelts into its ingot. Put an Iron Cluster, Copper Cluster, Tin Cluster, Silver Cluster, Lead Cluster, Nickel Cluster, Aluminum Cluster, Osmium Cluster, Platinum Cluster, Gold Cluster, or Poor Gold Cluster into a furnace or blast furnace fuel slot setup and pull out the matching ingot: Iron Ingot is not in the list, but Aluminum Ingot, Lead Ingot, Nickel Ingot, Platinum Ingot, Silver Ingot, and Tin Ingot are. Gold Cluster yields Gold, and Poor Gold Cluster yields Poor Gold. Use blasting for faster results where the recipe is available.

Nuggets

Several ingots break down into Nuggets for compact storage and trading: Aluminum Nugget, Copper Nugget, Lead Nugget, Nickel Nugget, Platinum Nugget, Silver Nugget, and Tin Nugget. Craft nine Nuggets back into one Ingot, or one Ingot into nine Nuggets, matching the standard metal pattern.

Coal and Coke

Coal-type blocks process through smelting and the coke oven. Lignite, Bituminous Coal, and Anthracitic Coal each have a coke oven recipe producing Lignite Coal Coke and Bituminous Coal Coke respectively. Peat is a fuel block you can burn directly. Keep a stack of coke for blast furnace runs and reserve raw coal blocks for torches and crafting.
