- Not to be confused with the unknown substance.
Unknown materials can appear as a placeholder as the result of bugs - specifically, missing material tokens. They have minimal material properties, typically appearing as a light gray solid unaffected by temperature.

An "Unknown material", as it is listed in building descriptions, normally has no name. It has an internal ID of -1 or [NONE], the same as used in tasks that require items of any or an unspecified material.
Doors and hatch covers in dark pitsBug:6776 and dead civilizationsBug:3478 have been known to generate as unknown material.
Since the material ID of -1 is used as a placeholder value for any material, items made of the unknown material cannot be specifically requested as an ingredient, even in modded reactions.
Organic substances[edit]
[CREATURE_MAT] and [PLANT_MAT] fall back to "unknown creature/plant substance" if they do not have a proper subtype. If solid, they will additionally be listed as "frozen".
Other forms[edit]
Other material categories have fallbacks in addition to their subtypes. Unlike unknown materials, they are functional when obtained.
Inorganic materials without a subtype become magma ([INORGANIC:NONE]), or generic "rock" if solid.
The generic form of charcoal and coke ([COAL:NO_MATGLOSS]) is known as refined coal, which cannot be legitimately obtained.
