It would be nice if it were possible to synthesize complex elements using simpler ones. This could open up room for more factories. (Yes, I did suggest this earlier, but I didn't want to revive an old topic.)
@The-Con(View Post) Not sure I have seen many saves that got direct contact between coal and salt or any of the others. I think it's quite a good idea opening up some chemistry to tpt
@Catelite did seem to support adding more reactions but she preferred more complex reactions. @Randalserrano mentioned a reaction involving BREL and I think BRMT that will form THRM.
