lime pops

Today I learned about cheesy tile. If the lime doesn't get mixed up right before they fire the tile, it makes bubbles that can break when you step on them, or even with practically no excuse at all. This is only an interesting side note until you come across some tile you really, really like, and it turns out to be seconds, so all the tiles have lime pops in them. Then it's really, really annoying, and you have to go back and start the tile hunt all over again.
