Pyrosium is dumb as heck

[Clarks]

I was able to set up a pyrosium mix that would go off in a predetermined amount of time (the catch
being that the timer is started the instant you take it out of the reagent heater).

How did I even forget to mention that you're tied to the heater. It would be much more useful if it only started heating the moment it came into contact with another reagent; think self-heating cups.
