ChemicalCraft

This mod adds many things, let's start with what you can get

1. Steel - The material is higher in strength than iron, the strength of the tools is 370 uses and is something between diamond and iron, it is also used to create a block of steel tiles.
2. Cast iron is a decorative material. It is used to create bars, cast iron block, door and trapdoor from it I could tell a lot more, but it spoils the impression of the first opening of the mod, and besides there are too many things to fit here. There are a lot of new ores in the mod, and each ore has its own position, for example, tungsten can not be found in ordinary stone but can be found in deepslate, and sodium can be found on the ordinary stone shores of the oceans.
