This item designed as some kind of "magic fuel". It have 6400 ticks burning time, - x4 more than coal. In "vanila" thaumcraft u need 1 coal and 3\3\3 potentia\chaos\ignis essentia( https://ftbwiki.org/Alumentum_(Thaumcraft_4) ) - so it takes 2+3 coal to get 2 alumentum. 5x1600(coal burning) and 6400x2(alumentum burning) - that makes alumentum a good fuel. At vanila thaumcraft.
In this pack alumentum craft needs 6\3\6 potentia\chaos\ignis essentia. That means 1 alumentum need 4 coal to craft itself - and it's useless as magic-alternative to coal. That's bad, in my opinion.

Please, add some boost to burning value of alumentum(up to 8000 for example) or reduse essentia costs(to 4\3\4 for example).
Wich increase the burnvalue.

12800 is the new Burnvalue . @Cinobi ok?
Looks cool!
i feel its overpowered, make it 7200 and it will be perfect
Default efficiency of alumentum is 125% (burntime of 4 coal while uses 3 coal to craft)
you made it 200% efficient
7200 will make it 112% efficient for its usage, so it both will be nerfed from default, but not useless already
no i think we let it at 125% so will change it to 8000.
me and cin talked about it, so i agree on 125% too, so 8k vote it is from me too
Nice
