Potential feedstock materials for gem-gum factories.
These could come packaged in microcapsules changing their profile in likelihood of and damage by spills strongly.

Special cases

• Acetylene – of particular interest due to it's low hydrogen content.
• Methane – a bit much hydrogen. This will mostly be burned to water.
• Ethanol – big molecule – lots of disassembly needed.
• Carbon Disulfide CS₂ – not environment friendly – water free solvent

Volatile elements right from the air

• Carbon dioxide CO₂ – as a source for carbon (energy devoid)
• Nitrogen N₂ – (energy devoid)
• Oxygen O₂
• Water H₂O – as source for hydrogen (energy devoid)
• Argon – not really a building material but super abundant useful for stabilizing structures by pressurization.

Mundane nontoxic salts

• Salts of carbonic acid
• Salts of nitric acid

• Salts of silicic acid – silicates don't like to be in solution - only with sodium or potassium this works halfway decent (sodium and potassium salts don't like to be unsoluble)
• Salts of phosphoric acid – phosporic acid is quite mundane (is uses in food) – many other phosphor compounds can be quite toxic
• Salts of sulphuric acid – mundane

• Table Salt NaCl

The alkali elements in there (Na,K) that are just added to keep the solution PH neutral (not acidic) are less useful for structural materials. They do not like to form strong directed covalent bonds as they are needed in strong structural high performance materials. So they may remain largely unused. Remnant lye (NaOH, KOH) can be neutralized with actively collected atmospheric CO2.

More toxic salts

• Salts of boric acid
• Sodium aluminates – There is no aluminic acid – just as slilicon aluminium hates to go into solution

Other mundane small molecules that could serve as resource carrieres

• Urea – highly inert and nontoxic nitrogen carriere
• Dimethyl sulfide – sulfur carrier – strong smell (smell of the sea in low doses)
