Thermite Array: Ball

Requested by , this is part of a series. Her request was a transmutation circle that caused a thermite reaction (a reaction between aluminum and iron under massive heat) that causes an explosive reaction.

This thermite array creates an "Orb" of thermite above the array. Once the orb is to size (whatever size you want), you can use the array to "launch" the orb. If you draw the array on your hand, you can launch it with accuracy.
The way the array works is like a mini sun, almost. The reaction wont occur until the transmutation is complete. It causes the dense, superheated material to react as it becomes unstable.

PLEASE NOTE!!! Those are nuclear reaction arrays, but I amped them up to work differently. They build up an element hydrogen atom by hydrogen atom. Its like this: X=1: X+1→X: X is the current atom. Once X equals the needed atom, it starts over after spitting out the atom.
I'm quite happy with how these turned out, but if I can find a better way, I will let you all know.
