Will get details on the main page shortly, but as far as I can tell, the basic operation works as follows:
- Feed it foods to learn techniques
- Salt with powders to change which technique you learn
In order to get the "Hopefully that'll all break down into Ecofuel", you need to feed it .2 gang stash worth of food at once (so 10 ancient candy bars, or 5 protein bars, or 2 acidic sushi). It took getting the "Hopeful' message 8-14 times to learn a technique. (data points: 8, 12, 14)
- Agar Powder = Ecofuel Fire
- Processed Sugar = Ecofuel Fire
- Sulphur = Acidic Ecofuel
- Red flakes = Ecofuel Fire
- Hound Dust, Dehydrated Eyedrops = Crystallized Ecofuel
- Gold powder = Glittering Ecofuel
- Rinsed squid eyes = Flowing Ecofuel
- Nova = Acidic Ecofuel
That covers all the categories listed on powder pouring except ashes of memory and achromatic powder which I don't have.
