== Mandatory properties ==
Inherits all properties from [[PrototypeBase]].
 
{{Prototype property|icons, icon, icon_size (IconSpecification)|[[Types/IconSpecification|IconSpecification]]}}
 
{{Prototype property|default_temperature|[[Types/double|double]]}}
Also the minimum temperature of the fluid. Has to be lower than <code>max_temperature</code>.
 
{{Prototype property|max_temperature|[[Types/double|double]]}}
 
{{Prototype property|base_color|[[Types/Color|Color]]}}
Used by bars that show the fluid color, like the flamethrower turret fill bar in the tooltip, or the fill bar for the fluidwagon tooltip; and for the pipe windows and storage tank fill gauges.
 
{{Prototype property|flow_color|[[Types/Color|Color]]}}
Used only for pipe windows or storage tank fill gauges.
 
== Optional properties ==
 
{{Prototype property|heat_capacity|[[Types/Energy|Energy]]|"1KJ"|optional=true}}
Joule needed to heat 1 Unit by 1 °C.
 
{{Prototype property|fuel_value|[[Types/Energy|Energy]]|"0J"|optional=true}}
 
{{Prototype property|emissions_multiplier|[[Types/double|double]]|1.0|optional=true}}
Scales pollution generated when the fluid is consumed.
 
{{Prototype property|subgroup|[[Types/string|string]]|"fluid"|optional=true}}
The value of this property may not be an empty string. It either has to be nil, or a non-empty string.
 
{{Prototype property|gas_temperature|[[Types/double|double]]|max value of double|optional=true}}
Above this temperature the <code>gas_flow</code> animation is used to display the fluid inside storage tanks and pipes.
 
{{Prototype property|hidden|[[Types/bool|bool]]|false|optional=true}}
Hides the fluid from the signal selection screen.
 
== Custom properties ==
The base mod reads the following property in data-updates.lua to determine if the fluid should be barreled. The property itself is not read by the C++ part of the game which means that it is discarded by the game when loading finishes.
* auto_barrel - [[Types/bool|bool]] - Optional, defaults to true. Whether the fluid should be included in the barrel recipes automatically generated in data-updates.lua in the base mod.
 
== Example ==
<syntaxhighlight lang="lua"> {
    type = "fluid",
    name = "water",
    default_temperature = 15,
    max_temperature = 100,
    heat_capacity = "0.2KJ",
    base_color = {r=0, g=0.34, b=0.6},
    flow_color = {r=0.7, g=0.7, b=0.7},
    icon = "__base__/graphics/icons/fluid/water.png",
    icon_size = 32,
    order = "a[fluid]-a[water]",
    pressure_to_speed_ratio = 0.4,
    flow_to_energy_ratio = 0.59
  }</syntaxhighlight>
