Primordial crock pots spawn around the world in any plains-like biome. Crocks can craft ore soups which will need 4 ingredients and 2 buckets of liquid stock to get two buckets of soup. The only soup currently craftable is Iron Soup, which is made from a beetroot, 1 raw iron, 1 gravel, and 1 gunpowder. Crocks have a four-slot internal inventory, an input tank, and an output tank. The output tank can be accessed through the front face (indicated by the spout) and the input tank can be accessed by any other face.
Liquid stock is obtained from draining a stock deposit, which are found in sandy biomes like beaches, deserts, and badlands. Stock deposits hold 16 buckets of stock and create one bucket per second. They can be drained using fluid pipes from other mods or any other way of extracting fluids.
Currently neither block supports dispenser input or output, but this is planned if I can figure out how to do it nicely.
Once the Crock is fully implemented, Ore soups can be created by inserting the item ingredients and 2 buckets of stock into a crock that is above a campfire. Two buckets of the ore soup, with the type determined by the recipe, will be created after a short time. To process the soup into ores, simply place the fluid down in the world using a bucket or other method, and wait for it to 'dry up' into an ore block. The drying process can be automated via vanilla redstone (soup buckets can be placed by a dispenser), or via other mods.
