How much charcoal do you actually put in each clay pot?

Yeah, I had that happen on a patio pour. The south facing edge where the sun beat down all day got a few hairline cracks, but the rest was solid. I'm starting to believe fiber just can't fight a bad temperature swing on its own. Now I focus more on the cure, keeping it wet and covered in those hot spots. The fibers are cheap insurance for plastic shrinkage, but they're not a magic fix for everything.

Ever notice how our brains latch onto color way faster than words? I mean my toolbox at home is a mess, but the red tape on the wrench set makes it the first thing I grab. It's like we're all just hardwired for that kind of simple, visual shortcut.

Your "if it ain't broke" instinct is right.

What storage method did you end up choosing?
