Yes, I like this. I find so many bowls and pots rifling through the depths of ruins. It would be nice to have a use for them. If they crack and break over time, it gives you a reason to continue to interact with the system. I'd like to add, the broken pottery could still be useful. In real life, fired clay pieces with no glaze that have cracked or shattered can be ground down to make what we call grog. It has a lot of real-world uses, but probably most the important translation to the game would be incorporating grog into wet, unfired clay makes it stronger and less likely to crack. A durability boost, if you will.
