Tin, bronze and steel are added as ores, ingots, blocks and nuggets, with full sets of tools and armor built from them. Copper and bronze blocks gradually change color over the years of play, though the change proceeds two to three times more slowly than in vanilla. Raw tin, ore storage blocks and textures based on older designs are included as well.

The Crucible Furnace is a new station that handles alloying. It needs 4 durability points from a Crucible to run and takes only certain fuels: coal, charcoal, coal blocks and lava buckets. Smelting in it runs two times slower than a regular furnace. Alloy recipes combine one tin with three copper to make three bronze ingots and one coal, and three iron with one coal to make three steel ingots.

Beyond the metals, the mod expands vanilla with functional fletching, garden tables and woodcutter blocks, a steel golem, luck potions, anvil repairs and new villager professions. Recipes for several vanilla items are rebalanced. The mod runs on Forge for 1.20.1 only, and the server and every player need it. It is released under the MIT License and is not open source.
