Display MoreSo it looks like special block: Reactor (chemical). It shows a slot to insert materials, slot for output and some scales.
1. Pressure (up to some limit)
2. Temperature (up/down to some limit based on biome)
3. Volume of each material inserted (up so some total limit)
4. pH
5. ...
Pressure can be manipulated by opening hole to release steam.
Heater/cooler can be EU based (battery slot + EU scale + thermostat controls) or item based (slot for ice/water/lava). Also some HEAT exchange possible between nearby Reactors (including Nuclears).
Volume increased by adding something and decreased by removing something. Also pH.
You can add anything into reactor and release any material in six directions.
If released into air, gas disappears, liquid flows away, solid dropped as items.
If released into nearby Reactor, added to other Reactor.
Recipes would be hardest. You need to describe how each material reacts with each in each condition. For example Iron with Coal in right temperature and proportions produce Steel with some rate. You need quite skilled Chemist to describe it all with a slightest sign of realism.
Good luck!
That sounds like a endgame time eater +1
And change steel with iron dust.
