(Very WIP: expect bugs and the like.)
This mod aims to add most, if not all elements of the periodic table to Factorio. Complex new production chains to refine and produce new ores and resources for your growing factory, and delving deeper into chemistry and production chains than a normal vanilla playthrough.

Sift through new "group ores", containing the elements of each separate periodic group (Alkali Metals, Transition Metals, etc) which can be broken down using new fluids or items to get a specific new resource, all in the name of expansion. Of course, not all elements can just be found in the ground; you'll have to sift through air, sea and ground to get everything you need to build further and research more.
