Enchanted Pottery Fragments

A lot of people are complaining that archaeology seems extraneous, so let's give the pottery some function!  First, make two categories of pottery fragments, mundane and enchanted.  Mundane would be artful only, and let's make the pot function as a flower pot and/or cauldron, as well.

Enchanted fragments would put enchantments on the completed pot.  The most common would have a glowing image on them, maybe the sun or moon, and they would make the pot emit light.  The effect would stack, so a pot with only one glowing sherd would glow dimly, and a pot with all glowing sherds would glow brightly.  

Much rarer enchanted fragments could make the pot give short range status effects, like a baby version of a conduit or beacon. To prevent them from being OP early game, status effect fragments couldn’t stack up or be combined except with glowing and mundane fragments, and the range would be very small, like touching the pot. Their effects might include things like regeneration, weakness, removal of all status effects (like milk does), and they wouldn’t last very long or be high level versions of the enchantment.  Powerful fragments would be rarer.

Having wandering traders sell fragments, sometimes rare ones, would make them more useful, too.  This has a lot of potential for creative, adventure, and survival maps.
