Chem Lib is a simple mod that adds plenty of chemistry related items including:
Chem Lib 是一个添加了许多与化学相关的项目的简单的mod，包括：
All 118 elements；
Ingots for all elements that make sense (i.e. all except for gases, mercury, iron, gold, etc)；
Several dozen chemical compounds, including several "drugs" that have potion effects when consumed。
All of the contents of this mod were originally included in the 1.12.2 version of Alchemistry, but it has been split up so it can be used by Alchemistry, Techemistry (Coming soon?), or by modpack makers without necessarily needing to include any other baggage.
