BalancedClay
Makes clay balanced!
This plugin adds recipes to turn clay into any item! Contains an extensive configuration for disabling certain items as outputs, disabling certain types of recipes, as well as specifying a blacklist or a whitelist.
Currently supported recipe types are:

• Crafting Table (generates a unique shaped recipe for each item in the game)
• - Furnace (Furnaces, blast furnaces, smokers, and campfires will all result in a random item when smelting clay)
• - Blast Furnace
• - Smoker
• - Campfire
• - Smithing Table (smithing tables will allow you to combine any item with clay to turn it into another item)
• - Stonecutter (stonecutters will allow you to turn clay into any item)

Each recipe type can be toggled in the configuration.
