Essentia Tube is a block added by the Thaumcraft 4 mod. Tubes can transport liquid Essentia from one place to another.

Machines, which can interact with Essentia will connect to the Essentia Tube when it is placed from the side of the machine that is either Essentia input or output. Tubes themselves do not do anything, but if the tubes connect 2 machines, the machine which wants to output Essentia to this tube, will scan all the machines attached to the tube blocks in the tube network which is connected to the export side of the machine. The nearest machine which can import this essentia in it will be marked as a destination for the essentia. After this the outputting machine will add information to all of the tubes along the travel route that the certain type of Essentia is being currently sent through this tube.

If the other machine sets the route which transports different Essentia which passes throught the same tube block, this tube block will be jammed. This can be recognised by a small Essentia fountain going through the tube to the air, and if left for long, will create Flux. The jammed tube block will send information about it being jammed to both machines which try to send Essentia through it. And then both Essentia types will try to change the route, and untill they succeed, or untill one of the routs is terminated, no Essentia will be transferred. When several routes of one type of Essentia intersect, no problem will be created.

When the route stays stable for 1 second and is not jammed, the Essentia will start to flow through this route. The flow speed can vary depending on the complexity of tube network, but is no more than 20 Essentia per second, which is 1 Essentia per tick. Normally this value is much lower, having 8 Essentia per second in average.

Routing different essentia types to go to multiple outputs can be difficult as these tubes work on suction. Only the highest suction will pass a pipe. This means that if there is 20 ordo suction and 19 perditio suction on a tube, it will take ordo, but not perditio.

Essentia Resonator can show which type of Essentia is currently transferred through each tube, making problem solving much easier.

Essentia Tubes
Transportation of essentia

Research aspects in this block[edit]

Thaumonomicon Entry[edit]

"You have discovered several ways to transport essentia, but none of them has proven useful for large scale alchemical operations - until now.

You have unlocked the key to creating stable and relatively leak-free tubing. While mundane chemicals can be transported in glass, certain types of essentia either dissolve or simply pass right through it. By wrapping the glass in iron and treating it with quicksilver you have managed to protect it from even the most volatile types of essentia. Gold fittings finish off the piping system and make it visually appealing.

The tubes can be connected to all manner of alchemical devices, though warded jars and alembics are their primary targets.

Essentia flows through the tubes whenever something is connected to them that can accept it, like warded jars.

Jars containing different kinds of essentia will only draw their kind of essentia towards them. Tubes however can only draw and transport one kind of essentia at a time - the highest drawing strength will take priority. Without the proper use of valves it is quite easy for a network of tubes to get gummed up. The use of valves is essential.

When you see gasses being vented from a tube, it means different kinds of suction are interfering with each other. The color gives a clue as to the types of suction.

The essentia valve acts much like a normal length of tubing, except it can be turned off by hand or a redstone signal. When this is done the flow off essentia through it will be cut off.

The Essentia Resonator is handy for troubleshooting your tube network. You can use it on a tube or other essentia using device to see what essentia it currently contains and the suction it is applying.

Tubes can be connected and disconnected from their neighbors by clicking on a section of tubing with a wand.

The wand can also be used to click on the central section to rotate certain tubes like the valve."
