Infinite mixing

Some liquids can be infinitely mixed (produced from themselves in any quantities using Liquid Mixer or by throwing the components into the lake), and are therefore easy to produce. Other liquids can't.

Because Water can be produced anywhere with a Well, any liquid that consumes Water during mixing is still considered "infinitely mixable".

Infinitely mixable liquids

 * Bio-Ooze (Healing Water + Bio-Ooze). Also exists in infinite quantities on some Gas Giant worlds.
 * Black Tar (Sulphuric Acid + Organic Soup), (Blue Grav-Liquid + Black Tar)
 * Blood (Water + Blood). Also exists in infinite quantities on most Atropus Sea worlds.
 * Blue Grav-Liquid (Water + Blue Grav-Liquid)
 * Coconut Milk (Salt Water + Coconut Milk)
 * Contaminated Water (Water + Contaminated Water)
 * Healing Water (Water + Healing Water). Also exists in infinite quantities at the core of some (but not all) Gas Giant worlds.
 * Liquid Irradium (Organic Soup + Liquid Irradium), (Black Tar + Liquid Irradium)
 * Liquid Protocite (Black Tar + Liquid Protocite), (Pus + Liquid Protocite); some Atropus Sea worlds have infinite Pus for in-world mixing.
 * Organic Soup (Poison + Organic Soup)
 * Poison (Water + Poison). Also exists in infinite quantities on Toxic worlds.
 * Salt Water (Water + Salt Water). Also exists in infinite quantities on Ocean worlds.
 * Sulphuric Acid (Water + Sulphuric Acid)
 * Swamp Water (Water + Swamp Water)

Liquids that are only infinitely mixable in some biomes

 * Essentia Obscura (Pus + Essentia Obscura, in Mixer only) - infinitely mixable only on Atropus Sea worlds, where Pus exists in infinite quantities.
 * Plasmic Fluid (Pus + Organic Soup, in Mixer only) - infinitely mixable only on Atropus Sea worlds, where Pus exists in infinite quantities. Also exists on Strange Sea worlds in infinite quantities.

Liquids that can't be infinitely mixed

 * Aether (exists in infinite quantities on Aether World oceans)
 * Beer
 * Caliginous Gas (exists in infinite quantities on some Gas Giant worlds)
 * Crimson Honey
 * Dark Water (exists in infinite quantities on Tidewater planets)
 * Exspiravit Honey
 * Frozen Honey
 * Helium-3 (exists in infinite quantities on some Gas Giant worlds)
 * Lava (exists in infinite quantities on Magma worlds, as well as in the core of most worlds, including the first Garden planet)
 * Liquid Deuterium
 * Liquid Erchius Fuel (exists in infinite quantities at the core of some Gas Giant worlds - only ~5% of Gas Giants have that)
 * Liquid Iron
 * Liquid Metallic Hydrogen (not mixable, but can be smelted from Metallic Hydrogen, which exists in infinite quantities on some Gas Giant worlds)
 * Liquid Nitrogen (exists in infinite quantities on Nitrogen Sea worlds)
 * Liquified Crystal
 * Mech Fuel
 * Mercury
 * Oil (not mixable, but can be centrifuged from Black Tar)
 * Orange Grav-Liquid
 * Pure Honey
 * Pus (exists in infinite quantities on Atropus Sea worlds)
 * Slime
 * Unrefined Fuel

Note that mixing is not the only way to produce liquids. For example, Liquid Nitrogen can be extracted from Nitrogen, which can be extracted from infinitely mixable Healing Water.
