akkamaddi's Classical Alchemy

The refined base metals are Cuprum Stannum, which are refined forms of copper and tin. Combining one ingot of each yields Pyropus Bronze, sometimes called Red Bronze, which uses the same catalysts as regular bronze and takes enchantments well. Fusing Pyropus Bronze with gold ingots using redstone dust as the catalyst yields Pulchrum Bronze, which keeps a sharp edge and reaches harvest level 3, enough to harvest obsidian. A third alloy, Tomb Bronze, is found in dungeon chests and on undead monsters.

The metal progenitors work much like steel and iron. Coal or charcoal as a catalyst produces a small chunk, bonemeal a medium chunk and gunpowder a large chunk. The mod requires SimpleCoreLib, SimpleOres2 and Fusion, and it can optionally use akkamaddi's Arsenic and Lace, which adds Tomb Bronze to the mix. Classical Alchemy is client and server, so the server and every player need it.
