while most buildings in this mod have a nice role to either work as up or sidegrades, i cannot see the point of the smeltrys smelting recipes.
the calcite-less recipes are originally enticing but are much less resource efficient (ranges but around 50% relative to foundries iirc) which is good esp for balance!
however the other melting recipes.. why? i get the idea of melting stuff and recasting it later for whatever needs may come up but take into consideration that 20 molten iron = 2 iron plates in a foundry,
in a smeltry the exchange rate is 40 plates for 20 molten iron, thats an astounding loss rate. if im missing something let me know but i think theres a minor oversight here
other than that loving the mod, the petrochem plant is a god send!!!!!! <3
