Quote from @mDiyo 's stream:

Imelchori: blaze reeds? that would be an awesome plant for the nether in natura. they >grow on lava lakes and instead of shugar, you can turn them into blaze powder

So basically, a sugar cane nether equivalent, can be turned into blaze cane powder (?) and 4 or 9 of them into 1 blaze powder. Also this powder can be turned into blaze paper which is oreDict paper (if that's possible) and it can be used e.g. (quoted from #tinkersconstruct IRC)

Fractuality: Also, blaze paper can be used in other fun things, like if you make a book >out of it, it can be named, etc, and then when read, it explodes

or

Vexatos:Like Blaze paper armor
Vexatos: 10 durability :D
Vexatos: No protection
Vexatos: yet fire resistance
Fractuality: Or, instead of fire resistance, it just lights you on fire

or

Fractuality> Blaze paper can be used be place on the ground/walls to light things on fire
Fractuality: When they walk over it, they get lit on fire, paper breaks

Opinions?
