After seeing https://powdertoy.co.uk/Discussions/Thread/View.html?Thread=21103
I wondered how many elements could be made starting with only two/three and using elements you created with a reaction between the two. For example Neutrons, plant and smoke can create oxygen and wood. How many more elements can be made?

So far I have found
Neut + gun (powder)= dust | dust + Neut = fwrk ||2 new elements
Nitr + Neut = desl | deal + Neut = oil || 2 new elements
@cxi2 Nice job 6 new elements from two
From 2: neut + gun = dust + more neut = fwrk + heat = embr + gun = fire = smke || 5 new elements
From 3: neut + gun = dust + more neut = fwrk + heat = embr + gun = fire = smke + plant (#3) = oxygen and next + plant = wood || 7 new elements
An extention of cxi's reaction:
NEUT + ELEC + heat + pressure + gravity = HYGN + NBLE + CO2 + OXYG + PHOT + PLSM + BMTL + more NEUT + more ELEC + maybe PROT + EXOT = CLFM + C5 = Pressure + PLUT = (STNE + URAN + LAVA + NEUT).
I haven't seen PROT in fusion thorugh.
SPRK can be made to make any element.
